Pearl Jewelry: Basic Knowledge

by Vasiliki Spyropoulou |

Pearls are a symbol of good luck, timeless elegance and youth. They provide optimism, well-being, health, longevity and strength. They have a unique property: the more you wear them, the more they shine ... the pearl is a living organism.

1. How They Are Created

Growing pearls is a work of love. Exact details vary from farm to farm and from species to species. For example, oysters can be harvested and the period of care before pearl is implanted varies.

2. Pearl varieties

The wonderful variety of pearls makes them even more unique. These sea gemstones vary in luster and color, depending on the type of oyster that produced them. Here's a guide to understanding the wide range of pearls.

Freshwater: Produced mainly in the lakes and rivers of China which is a pioneer in this genre. Freshwater pearls are grown in mussels, not oysters. Ten to fourteen freshwater pearls can be grown in mussels. Perfect round freshwater pearls are extremely rare.


Akoya: Awarded for their brilliant shine and rich color, Akoya pearls are a traditional symbol of elegance and beauty. Produced from Akoya oysters in Japan, they are the most popular of all pearl types. Depending on the size of the mother oyster, they range from 3-10 mm. Akoya pearls are typically white, some may possess golden or silvery-blue undertones.


Black South Sea: The stunning color of these natural black pearls is produced by oysters in the waters of Tahiti, French Polynesia and Okinawa. Sizes start at 8mm, in round and other shapes. Although the main color is black, the rich, dark colors vary from gray, silver, green to shades of green or blue colouring.


White South Sea: These treasures are typically the largest and most expensive variety of pearl. Part of their mystique is the fact that they are grown in the infamous “coral triangle” – a section of treacherous water that lies between Australia, Indonesia, and the Philippines. South Sea pearls range in size from 8-20mm, with pearls larger than 15mm going for tens of thousands of US dollars. Depending on the type of oyster they form in, they can be a silky white (similar to an Akoya), a sleek silver, pastel pink, or a rich gold.


3. Qualities of Pearls

Luster: Luster the amount of light that a pearl reflects both from its surface and from the deep reflection of its inner light. The better the quality of the pearl, the higher its luster. We provide high quality pearls with strong luster. Within a pearl type, when other quality factors are equal, the higher the luster, the more valuable the pearl.


Surface: Like colored stones, most pearls never achieve perfection. Some might show abrasions that look like a series of scratches on the surface, or a flattened section that doesn’t affect its basic shape, or an irregular ridge that looks like a crease or wrinkle. If surface characteristics are numerous or severe, they can affect the durability of the pearl and severely depress its value. Surface characteristics have less effect on the pearl’s beauty and value if they are few in number, or if they are minor enough to be hidden by a drill-hole or mounting.


Color: Pearls vary greatly depending on the type of oyster that produces them. The rarer the shade, the more valuable the pearl. Colors range from cream (white), pink and lavender to black or gray. White and pink are among the most popular colors in freshwater pearls. In addition to freshwater pearls, we provide Akoya and South Sea pearls. Both Akoya and South Sea are considered the top qualities of pearls. While color choice is a matter of personal preference, always look for rich color, evenly distributed throughout the pearl.


Size: While size does not affect the quality of cultured pearls, it does affect the price. Large pearls are more difficult to cultivate and their rarity makes them more valuable. Pearls are measured in millimeter increments relative to the diameter of the pearl.


4. How to Buy Pearls

Genuine pearls (natural or cultured), with the exception of high quality pearls, have many defects due to their formation. Since pearls are formed by a natural process in an oyster, it is very difficult to find perfect pearls. Most pearls have some surface spots (blemishes) that indicate a genuine pearl.
