Pearls have long been prized throughout the world for their grace, versatility, and eternal beauty and maintenance. But not all pearls are the same. Akoyas have an unparalleled lustre while Tahitian and South Sea pearls have a more exotic appeal-they all differ in their characteristics, shapes, and colours. This particular guide will lead you on an intriguing journey that will help you understand the types of pearls, the skill behind their shaping, and the different colors that differentiate them. Whether you are a collector or just someone with an interest in these natural wonders, this article will give you the vital information necessary to appreciate and understand the wonderful array of pearls.
Understanding Pearl Types
Pearls are typically classified based on their origin and process of formation. The chief varieties include natural pearls, cultured pearls, and imitation pearls.
Natural Pearls: These occur inside mollusks without human interference and are very rare and valuable.
Cultured Pearls: These are the most encountered pearls in the market, made by different controlled processes dependent on the environmental and genetic conditions of the mollusk.
Imitation Pearls: Made by man from materials such as glass or plastic, they remain a more cost-effective alternative to real pearls but lack luster and durability.
Knowledge of such types will help you recognize and select pearls that best meet your preferences and needs.
What is a Pearl?
A pearl is a tough and glossy object that is created inside the flesh of a mollusk such as an oyster or a mussel. Pearls are primarily made of calcium carbonate in the form of aragonite or a combination of aragonite and calcite and form when an irritant, like a grain of sand or a parasite, gets into the shell. The mollusk secretes layer upon layer of nacre around the irritant to appease it, and the result is a pearl. It takes anywhere from months to years, depending on the species of mollusk and environmental factors.
Natural pearls are far too rare, having never been cultivated and developed without human intervention. Today, most of the pearls making their way into the market are cultured pearls; that is, pearls grown on farms with human aid by deliberately stimulating an internal formation by inserting a nucleus into the mollusk. The worldwide pearl cultivation market was valued at around $10.7 billion in 2022 and continues to grow steadily. Akoya, Tahitian, South Sea, and freshwater pearls are among the most common types, valued according to their sizes, colors, and luster properties.
Thanks to recent developments in pearl-farming technology, the sustainability of production was further enhanced so that its environmental impact is kept to a minimum. Many pearl farms follow eco-conscious principles, as mollusks act to filter water and assist in maintaining the health of marine ecosystems. This dual identity of pearls as a precious luxury item and as a remarkable product from nature nurtured by human hands is truly fascinating.
Classification of Pearl Types
Pearls are named according to their origin, color, size, luster, and climatic conditions. Below are basic pearl types with the latest information:
Akoya Pearls
These pearls are famed for their perfectly round shape and radiant mirror glare. They are mainly produced in Japan and China. Akoya pearls are generally smaller in size, ranging from 6mm to 9mm, and are commonly found in white, cream, or light pink shades. It is understood that recent developments reflect how some Akoya pearl farms have now been able to successfully cultivate slightly larger Akoya pearls of better quality, so-called “Hanadama” grade.
South Sea Pearls
The South Sea pearls take pride in being the biggest and the most precious pearls, hence given the title “The queen of pearls.” They are mostly found in warm-water areas lying between Australia, Indonesia, and the Philippines. Usually, these pearls are about 10mm to 16mm and vary in white, silver, and golden colors. Recent information suggests that sustainable methods in the cultivation of South Sea pearls have brought in better quality, which has stoked higher interest in the golden South Sea pearls.
Tahitian Pearls
Black pearls are well-known under the umbrella term Tahitian pearls for their dark and exotic color spectrum-black to green, blue, purple, and many others. Most commonly, they are conjured in the offspring waters of French Polynesia, size 8-14mm. From 2009 to 2013, the growing trend of jewelry design was focused on their unique baroque (non-round) forms, which enjoy an inordinate demand among designers in contemporary days.
Freshwater Pearls
They are cultivated in freshwater rivers and lakes, mainly in China. A wide variety of these deposits exhibit various shapes, colors, and sizes. The freshwater pearls have been less priced than salt pearls, and colors like white, peach, lavender, and pink are common variants. Technology has successfully produced larger and better-quality pearls up to about 15mm.
Keshi Pearls
Being a sort of byproduct of pearl cultivation, Keshi pearls are nacreous, hence bearing exquisite lusterworthiness. They are present in many shapes and bear high values for their unique forms, which are all-natural. These are becoming popular now because of their rarity.
Mabe Pearls
Mabe pearls are hemispherical pearls formed inside the mollusk’s shell, mostly used for earrings and pendants. These pearls come in various colors and are appreciated for their affordability and suitability for statement-type jewelry.
Global Production Trends
The year 2023 sees an increase in worldwide demand for pearls, with a greater stress on being eco-friendly in the industry. The major producers continue to be Japan, China, Australia, and French Polynesia. Sustaining techniques in aquaculture are well on their way to replacing traditional methods, as these make sure pearl farming retains a balance between market demands and safeguarding marine ecology. Recent market data would put the cultured pearl industry value at roughly $10 billion per annum, growing steadily on luxury consumer trends.
Natural vs. Cultured Pearls
Natural pearls exist as a wonder of nature, where a strange particle makes its accidental entry into an oyster or a mollusk. Such pearls are incredibly rare and have traditionally remained much sought after, often fetching enormous value in the market. It is deemed that only 1-out-of-10,000 wild oysters produces a natural pearl, thus giving natural pearls somewhat of an exclusivity aura in the jewelry sector. Only a tiny percentage of pearls by share belong to the global pearl trade, which is led by the rare natural pearl.
Cultured pearls, on the other hand, are produced under strictly controlled farming methods. In actuality, some irritant (whether it is a bead or tissue) is deliberately introduced into the mollusk to give it nacre, thereby forming a pearl. More recently, advances in aquaculture have allowed cultured pearls to be more uniform in size, shape, and color, meeting consumer demands for pearls that are of high quality yet relatively inexpensive. The market of cultured pearls covers many well-known varieties, such as Akoya, Tahitian, South Sea, and freshwater, while also being a driving force for industrial growth. For instance, South Sea pearls with their large sizes and golden colors are ranked extremely high among cultured pearl types.
Another recently published pearl industry data set goes on to emphasize that the majority of pearls sold globally today are cultured pearls, which account for 95-99%. Simultaneously, cultured pearl farming has been innovated so that modern cultured pearl production has the least possible environmental impact, thus meeting the demand for ethical and environmentally conscious luxury goods. This dichotomy between natural and cultured pearls provides the consumer with several options, which cater to different price tags, tastes, and values.
Freshwater Pearls
Freshwater pearls are produced in mussels mostly in lakes, rivers, and ponds. They are sought after for their variety in shape and colors and the fact that they are relatively inexpensive when compared to their saltwater counterparts. Generally speaking, the freshwater type is less expensive but very good in quality and fairly hard. This makes it very popular in jewelry for almost all occasions. They are readily available and used in many versatile designs that can accommodate casual and formal attire.
Characteristics of Freshwater Pearls
One might say freshwater pearls offer every conceivable shape and size, and thus, backdrop every jewelry setting. Saltwater pearls favor the round and look for symmetry, whereas freshwater pearls have plenty of irregular shapes, such as baroque, oval, teardrop, and button. Contemporary farming methods have helped in raising the quality to such an extent that many freshwater pearls now stand neck and neck to calculated saltwater pearls in surface luster and thickness of nacre.
They are found in white, pink, lavender, and peach in their original state, but colors abound for dyed pearls. Freshwater pearls are said to be between 5mm and 12mm, with the bigger and finer ones being the rarest and costly. Freshwater pearls currently make up roughly 90% of pearls produced annually, making up most of the world’s pearl market, according to recent market data.
One of the defining traits of freshwater pearls is their durability. Since they consist of almost pure nacre, they cannot easily chip or peel, as opposed to their counterparts that matured around a nucleus, as in many saltwater pearls. They are even less expensive than many saltwater varieties, which makes them desirable for use in both everyday and expensive jewelry.
Common Shapes and Colors of Freshwater Pearls
Freshwater pearls are celebrated for the countless varieties in shape and color, appealing to every preference and style. Generally, freshwater pearls are not cultured around a nucleus, as opposed to marine pearls, which gives them the chance to develop diverse shapes. The most common definitions for the shapes are round, oval, button, drop, and baroque. Perfectly round pearls are rarely available and are more expensive, whereas baroque pearls are appreciated for their artistic and one-of-a-kind appearance owing to unique irregularities in shape.
In terms of colors, freshwater pearls offer an inspiring palette. Naturally, they range in color from white to pink, peach, lavender, and cream. With the improvement in cultivation technologies, certain types of freshwater pearls are also subjected to treatments to attain colors that are much brighter and exotic, such as deep purples, metallic gold, or multi-colored overtones. White pearls are still a classic choice, symbolizing elegance and purity, with other shades like lavender or peach being trendy choices.
The global demand for colored freshwater pearls has grown steadily in recent times, especially in the worlds of fashion and customization. Many jewelers are taking to incorporating uniquely shaped pearls into their contemporary designs, which is a reflection of this trend toward uniqueness and self-expression. More to the point, the diversity in shapes and colors stands behind the worldwide appreciation for freshwater pearls as a versatile and classic choice.
Value and Uses of Freshwater Pearls
These wonderful pearls are admired for their value, versatility, and variety. In comparison to the common saltwater pearls, freshwater pearls are from mussels instead of oysters, hence spawning more and opening up a greater spectrum of sizes, shapes, and colors. This accessibility makes them kind of a choice for both high-end and everyday designs.
According to recent research, the global pearl jewelry market was valued at approximately $11 billion in 2022 and is expected to grow at a CAGR of more than 5% between 2023 and 2030. Growth is being driven by the increasing consumer preference for sustainable and natural materials in fashion. Consequently, the freshwater pearls are marked as deserving their respect because they are environmentally friendly in their culture methods and even benefit aquatic ecosystems.
Freshwater pearls are combined in varieties of classic designs, such as necklaces and earrings, as well as impromptu designs for fashion accessories. Many modern designers also choose to incorporate pearls into mixed media designs, combining them with gemstones, gold, or silver to satisfy the contemporary operation of gems and metals appearing more subdued nowadays. Symbolically and culturally, freshwater pearls carry great significance-cliff-edge, love, and calm. The price of pearls, alongside the versatility of design, has cemented freshwater pearl jewelry as an eternal and cherished entity.
Cultured Pearls
Cultured pearls are produced when a small bead or piece of tissue is implanted into a mollusk to stimulate the formation of a pearl. The process itself is very meticulously controlled to produce pearls of uniform quality and size. They can be found in different shapes and colors and include Akoya, Tahitian, South Sea, and freshwater types. Cultured pearls constitute the greater part of pearls available in the markets today, thus presenting an opportunity for the layman to appreciate that level of elegance.
Overview of Cultured Pearls
Cultured pearls present an excellent example of human creativity combined with natural beauty. Recently, it has been stated that more than 90% of the global pearl market has been composed of cultured pearls, owing to their availability and uniform quality. A few major countries that culture pearls are Japan, China, French Polynesia, and Australia, which make up a sizable chunk of their economies.
The four main types of cultured pearls can be distinguished by their species’ distinctive features:
Akoya Pearls: Considered the most symmetrical and having superior luster, Akoya pearls are mostly cultured in Japan and China. Measuring from approximately 6 mm to 9 mm in diameter, these pearls are favored for their classic white or cream coloring, often with a rose or silver overtone.
Tahitian Pearls: Tahitian pearls originating from French Polynesia are very much desired for their uncommon shades of black, green, blue, and purple. They usually measure 8 to 15 mm, with larger pearls being rarer and more valuable.
South Sea Pearls: Cultured in the warm waters of Australia, Indonesia, and the Philippines, South Sea pearls are the largest and most lustrous of all cultured pearls, generally measuring from 9-20 mm. They come in very attractive colors such as white, champagne, and gold.
Freshwater Pearls: Mostly produced in China, freshwater pearls are appreciated for their lower price and wide variety. They are available in myriad shapes and sizes and present in natural shades such as pink, lavender, white, and peach, with sizes generally ranging between 4 mm and 14 mm.
With the strengthening demand for sustainable yet prestigious jewelry, the worldwide pearl industry, valued at $13 billion by 2023, is growing further. Cultured pearls stand as the epitome of sustainability, with a near-nil environmental impact cultivated through improved farming practices that take into consideration the health of oysters and their ecosystems. Technological intervention has further resulted in improved nucleus insertion techniques to enhance the quality and longevity of cultured pearls, thus is to the continued advancement of their adoration through future generations.
Akoya Pearls: The Classic Choice
Akoya pearls are acknowledged for their timeless elegance and exquisite quality and therefore are a forever classic in jewelry. Predominantly from Japan and China, these pearls are produced by the oyster called Pinctada fucata and are cited for their perfectly round shape, high lustre, and gleaming white or cream base colors with soft overtone shades of rose, silver, or gold.
The size of Akoya pearls is smaller compared to that of other types, ranging from 6 to 9 millimeters, but their consistent charm and symmetry have made them favorites for necklaces, earrings, and other finery. Japan is the premier exporter of Akoya pearls, the best of the crop, and the industry itself is a healthy share of the global cultured pearl market, which was worth more than $13 billion in 2023. According to recent reports, due to improvements in pearl farming, water quality management, and precise cultivation methods, the climate for Akoya pearl quality and sustainability has been severely improved.
Akoya pearls have also attracted interest due to their environmental sustainability. Pearl farmers have found ways to ensure ecologically sound measures for keeping the oysters alive and their ecosystem intact. Enhancing a little more to the value of Akoya pearls is the longevity and durability of such pearls, hence cementing their status as worthy ageless gems capable of staying alive to inspire and cast their charm down onto future generations.
Tahitian Pearls: The Unique Colors
The colors of the Tahitian pearls were said to be their best contrasting advantage from other types of pearls. These were unlike regular white pearls-one black in color with iridescent shades of greens, blues, silvers, or even peacock-like overtones. This coloration occurs because of the black-lip Pinctada margaritifera oyster of French Polynesia, which thrives in the warm lagoons.
Around 18-24 months is taken by a single Tahitian pearl to form, with the color varying according to the oyster’s shell color, the quality of water, and the environment of pearl cultivation. Tahitian pearls are still highly demanded in jewelry markets today, especially the peacock-hued pearls that are considered rare and most valuable. Their average size ranges from 8 mm to 15 mm, hence making them larger than Akoya pearls and smaller than South Sea pearls.
Taking the view of their color diversity as well as the cultural significance was considered luxurious and mystical, and in Polynesian culture, they were perceived as blessings from the moon and sea. Today, these pearls continue to arouse interest among collectors and jewelers alike, owing to their beauty and the industry’s environmentally conscious cultivation methods that help preserve their ecosystems.
Unique Types of Pearls
Akoya Pearls
Generally recognized for their classic beauty, Akoya pearls are usually small, round, and of high luster. More often, they’re colors of white or cream with subtle overtones of rose, silver, or ivory.
South Sea Pearls
Among the largest pearls, these are prized for their satin-like luster and hues varying from white and silver to golden. They are grown mostly in Australia, Indonesia, and the Philippines.
Tahitian Pearls
Known for their exotic dark hues, Tahitian pearls are naturally found in colors of gray, black, and green. They are mainly cultured in French Polynesia.
Freshwater Pearls
Made by freshwater mussels, these pearls are highly versatile, presenting various forms, sizes, and colors. They tend to be more affordable while still offering aesthetic appeal.
Baroque Pearls: Beauty in Imperfection
Baroque pearls are pearls of unique shape, celebrated merely for their irregular, asymmetrical contours, defying any attempt at describing them in normal terms, let alone the classical spherical pearl. They are formed when, during the formation process, conditions such as uneven nacre deposition or the position of the pearl within the mollusk may confer some special shape. Baroque pearls typically take an oval, teardrop, and abstract form, hence making them a favorite with designers wanting to come up with bolder or unconventional looks.
In recent times, growth in baroque pearl demand has been witnessed by the luxury market because of their one-of-a-kind appeal. They are yet cultivated by other saltwater and freshwater mollusks, with South Sea and freshwater pearls being especially notable producers. These pearls are usually favored by those who cannot afford perfectly round pearls but enjoy their exotic charm. With their dramatic look, baroque pearls have gained popularity, especially among designers for statement pieces in pendants and earrings that resonate with modern fashion trends.
Value considerations include luster, surface quality, dimensions, and that all-important distinctive shape. Certain baroque pearls, notably the gigantic, lustrous South Sea kinds, can be sold for large prices, which is what makes these unique yet moderately priced pearls interesting for collectors as well as ordinary buyers.
Round Pearls: The Ideal Shape
Round pearls were and still remain a typical embodiment of classical elegance in the pearl world. These pearls, having a perfect spherical shape, reflect light evenly, imparting a breathtaking luster so much desired for all time. Almost 70% of those who purchase pearl jewelry opt for the round type, according to industry sources, due to its symmetry and awesome appeal.
They are more difficult to cultivate, thus increasing their price in the market. According to studies, less than 10% of all pearls harvested are truly round, hence considered rare and desirable. In particular, there is a huge demand for brilliance and perfectly round shape of cultured Akoya pearls, whose typical size is from 6mm to 8mm. South Sea and Tahitian round pearls are considered rarer and therefore exhibit high premiums, especially when sizes are from 9mm to 16mm.
With their consistent shape, round pearls are preferred as heirloom-quality necklaces and earrings that add elegance to both formal and informal attire. Round pearls are mostly joined with gold or platinum so that their beauty may be further amplified and then there is just no limit to the kind of stunning designs which can be created.
Comparing Different Unique Types of Pearls
The most precious pearls always differ slightly in their origin, nature, and value in the jewelry market and cultural aspects. We will take a deeper look at some of the more preferred types of pearls:
1. Akoya Pearls
Akoya pearls are prized for their round form, great luster, and classical white or cream colors that have overtones of silver, rose, or ivory. Mainly produced in Japan and China, they range from 6 to 9 millimeters in size. Akoya pearls signify an old-world charm with a touch of elegance and are classic choices for strands. Market reports show that Akoyas derive their price attributes from the uniformity of size and color, pure surface quality, and brilliant luster, with good strands fetching food prices.
2. Tahitian Pearls
Tahitian pearls have their own rarity in that they go by natural dark colors, ranging from charcoal gray to black, splashed with attractive overtones of peacock green, aubergine, or blue. The pearls are farmed in French Polynesia-MS9999-imitate, and their exotic look must have contributed immensely to their fame and demand. With sizes ranging from 8 mm and 14 mm, these pearls stand quite tall among others, with some superior ones standing much taller. They become scarcer and rarer with the rise in demand, with the asking good price, especially for those with crystalline surfaces and vibrant overtones.
3. South Sea Pearls
Often called “The Queens of Pearls,” South Sea pearls lie among the largest and very rarest cultured pearls in the world. Nurtured mainly in Australian, Indonesian, and Philippine waters, these pearls come in white, silver, and gold shades with a size range of 9mm and above, reaching 16mm. Their silky luster and naturally milky satin appeal to pearl-lovers. Due to their rarity and large size, South Sea pearls shine with super premium prices, with strands selling for north of $10,000.
4. Freshwater Pearls
Freshwater pearls are cultivated in rivers and lakes and mainly in China, known for their great diversity in shape, color, and affordability. Unlike other types, they tend to have irregular or oval shapes, although now round freshwater pearls are increasingly common because of new farming techniques. They come off as 5mm to 12mm in sizes with natural hues as well as dyed ones, offering great flexibility in options for present-day jewelry designs.
5. Keshi Pearls
The key value of Keshi pearls is their complete natural origin: they are but a byproduct of the process of culturing pearls. These pearls own renowned luster; freeform, irregular shapes with sizes and colors are varied. These pearls would be quite rare and sought after for artistic and organic statements for jewelry.
Latest Market Trends
Reports indicate a growing interest, especially for larger pearls of South Sea and Tahitian varieties, spurred by issues of rarity and aesthetics of a higher order. Further, pearl farming sustainability is at the core of concern, with buyers probing the ethical aspects of eco-friendly farming practices. Freshwater pearls, on the other hand, remain a favorite for their cheaper option and unlimited color array, endorsed heavily by the younger generation.
Understanding those special features and traits of these pearl types allows buyers to look more tangibly into their buying decisions, factoring in preference, budget, and motive behind the jewelry piece.
Characteristics of Pearls
Pearls are valued for their natural beauty, natures of luster, and variety. The following are some basics:
Shape: Pearl shapes range on different scales from round, oval, baroque, and near-round. The round ones have been considered the most classic and valuable type.
Color: Pearl colors are anything from whites and creams to pinks, lavenders, or blacks, and they can present overtones that add much to their actual appearance.
Luster: Luster is the ability of a pearl to reflect light directly and thereby plays a great role in indicating a pearl’s quality; in the best pearls, the luster is bright and mirror-like.
Surface Quality: Most pearls have some natural imperfections or blemishes, though depending on fewer marks make a pearl far more precious.
Size: Pearls come in different sizes; most sizes are measured by millimeters, and bigger pearls are sometimes more valuable.
Types: These are the types of pearls: freshwater, akoya, South Sea, and Tahitian; each has variances in purity, shape, and price.
The selection depends upon the taste and requirement you want; so it helps when you know much about these details.
Color Variations in Pearls
Pearls showcase a stunning array of colors: each influenced by the type of mollusk producing them, the cultivation environment, and even by the thickness of the pearl’s conchiolin layer. Colors observed usually include white, cream, yellow, gold, pink, silver, and black. Sometimes, there are also overtones, which are faint secondary hues of colors such as rose, green, or blue, adding to the possibility of beauty and rare uniqueness offered by the pearl.
In fact, Akoya pearls have been widely known for their traditional white hues with a faint hint of rose or silver overtone, thus making them much sought-after for traditional jewelry. While Tahitian pearls, principally cultivated in the French Polynesian waters, are best known for their exotic, darker colors, with shades ranging from peacock green to glowing gray and purple. Similarly, South Sea pearls grown in Australian and Philippine waters are bestowed with luxurious golden or silvery colors due to the types of oysters within these waters. Meanwhile, Freshwater pearls, abundantly grown within China, flaunt pale tones of peach, lavender, and pink at comparatively lower prices.
Speedy colors would affect a pearl’s worth tremendously. For instance, rare natural colors of black and gold are highly sought after. Along with the considered technique of pearl cultivation, treated pearls and dyed varieties have come up, able to create bright colors out of the usual shades and cater to a wider aesthetic spectrum. Choosing pearls based on colors might consider skin tones, style, and favored overtones as guidelines toward solutions.
Factors Affecting Pearl Shape
Pearl shape depends on a variety of factors, mainly arising from the natural and environmental conditions during its formation. One of the main factors is the kind of mollusk used for pearl cultivation, with each species producing pearls peculiar to its anatomy. Akoya oysters would, for example, produce round, lustrous pearls, whereas freshwater mussels would commonly give baroque or irregular shapes.
The size and shape of the nucleus or irritant that is introduced within the mollusk during the process of cultivation constitute another big factor. A perfectly round nucleus would more often produce a round pearl, whereas an irregularly shaped nucleus would result in baroque or otherwise uniquely shaped pearls. Approximately 30 percent of cultured pearls are almost round, while only 1 to 5 percent are truly round, making the latter more valuable.
Water quality, temperature, and stress factors on the mollusk are some other variables that enter the picture. Enhanced symmetry and good formation happen when pearls grow under superior conditions, but any disturbance during cultivation can cause the dots to give odd-shaped pearls. Freshwater pearls undergo changing conditions more frequently than saltwater pearls.
With the refinement of the techniques in pearl farming, some of these variables can be controlled better now. However, since there is still much natural variance in the growth process, every pearl is truly one-of-a-kind. Whether they are aimlessly round or intricately baroque in design, these factors together dictate the charm and shape of the pearl.
Understanding Pearl Luster and Quality
One of the most defining aspects that ranks a pearl would be pearl luster, as it describes how light interacts with the surface of the pearl and with its inner layers. If a truly good pearl possesses bright, sharp, and mirror-like reflections, it is often termed “brilliant.” A pearl seeming dull, chalky, or duller in reflections would be lower in value.
The luster depends on the nacre thickness and quality, that is, the organic substance secreted by mollusks and deposited layer by layer around a nucleus to form a pearl. For natural pearls, the nacre layers tend to be thicker, giving them remarkable luster and depth. Similarly, enough time must be given to cultured pearls to build adequate nacre layers so that the techniques involved in pearl farming and the species of mollusk can produce pearls with stunning luster.
Luster is consistently considered one of the most crucial factors in these grading systems, such as the AAA-A grade scale, for freshwater and saltwater pearls alike. Pearls given a grade of AAA show the finest luster, which is crisp and most reflective. Comparatively, those given a grade of A have deteriorating luster with less sharp reflection.
In assessing the quality of pearls, one should not fail to look at the cleanliness of the surface, overtone, which is the faint color overlay on the base color of the pearl, and its symmetry. All such parameters complement the luster and, hence, the general look. Buyers of pearls should keep these points in very close view, whether buying for investment in jewelry or for mere amusement.
Advancements in pearl farming technology are now providing pearl farmers more control over environmental factors affecting pearl luster. Improvements in water quality management and mollusk healthcare are tilting the scales toward consistently producing pearls with radiant luster worthy of the market’s demand for top-grade gems. Another important factor is educating the consumer about the luster and quality of pearls, which has begun to empower buyers to make more educated purchase decisions.
