A number of factors affect the appraisal of pearl quality. We recommend that customers learn the basics of selecting fine pearls to make pearl buying an enjoyable experience and to ensure a sound investment.

Pearls Size
Pearl size is mostly determined by two factors: the size of the implanted nucleus and the thickness of the nacre that grows layer upon layer around the nucleus. A large cultured pearl that lacks nacre thickness has a low value, and tends to discolor and crack fairly easily. A pearl with a thick nacre coating will retain its luster and beauty for a lifetime when properly cared for. For pearls of similar quality, the most important other determinant of price is the size of the pearl. The size is generally measured in millimeters.

Pearls Shape
Perfectly round cultured pearls are the rarest. Although most cultured pearls are nearly round, only about 1% is perfectly spherical. To check a strand for roundness, roll it across a flat surface. The strand should move evenly and smoothly.

There are three main types of cultured saltwater pearls: akoya, Tahitian, and South Sea. Pearls can be cultured in fresh water as well. Each type has distinct characteristics, and each is very beautiful in its own way. Like with most things, individual tastes determine pearl preferences. Or you may have a taste for every pearl variety! The following is a look at the main types of cultured pearls.

Akoya Cultured Pearls
Timeless and popular, the akoya cultured pearl probably comes to mind when you think of pearls. (Because akoyas are easier to match than other pearls, they are a popular choice for bracelets and necklaces.) These saltwater beauties are typically small (they range between 2mm and 11mm; average is 6mm-7mm), and are most commonly white or cream-colored.

Akoyas are produced in the akoya oyster, or P. fucata, the smallest of the saltwater pearl oysters. The main animals used for saltwater pearl culturing in Japan, these small oysters typically reach only 8cm to 13cm in diameter, but they can accept multiple nucleations—up to five at a time. (If a larger pearl is desired, however, only one bead is inserted.)
Akoya pearls were the first round cultured pearls—called “spherical” in the jewelry trade—that were produced. Approximately 70%-80% of a given akoya crop is spherical. Typically white or cream with rosé or green overtones, akoyas typically grow from eight months to two years before they’re harvested. A jewelry staple, the simple and classic white akoya strand is a popular choice for brides.

Tahitian Cultured Pearls
If you think of black pearls, you probably picture a peacock-blue-sheened Tahitian. This is a desirable hue for a Tahitian cultured pearl, but they can also be black, gray or brown with hues of blue, green, and purple and overtones of rosé, green or blue. Marketed just since the 1970s, Tahitians are revered for their exotic colors and large sizes, and, as you may have noticed, their large price tag reflects their relative rarity.

Tahitian pearls are produced mainly in French Polynesia in the so-called “black-lipped” oyster, P. margaritifera, a large saltwater mollusk that can grow up to 12 inches in diameter, weigh up to 11 lbs. and live up to 30 years. These oysters produce pearls that reach 8mm-14mm in size in a growth period that takes about two years.

Tahitian cultured pearls typically show fair to excellent luster, and achieve this by natural means, unlike akoyas and freshwater cultured pearls, which require treatment—usually bleaching—to bring out their sheen. When Tahitians are harvested, farmers wash them in fresh water, dry them and lightly buff them, usually by tumbling the gems with ground salt and bamboo chips.

P margaritifera can be nucleated, or implanted, several times over its lifetime, but in general, the first harvest produces the finest quality pearl. Unlike its smaller cousin, the akoya, Tahitian cultured pearls are spherical less than half the time. For this reason, it may take years to find just the right pearls to match for a necklace. This is one of the reasons why a matched strand of Tahitian cultured pearls is so costly. Because they can often come in unique shapes, however, Tahitians are used by many jewelry designers in pieces that feature a single pearl. These pieces are uniquely beautiful and can be as breathtaking as a costly Tahitian strand.

The luster of pearl jewelry is enchanting. Whether it’s a pearl necklace or a pair of pearl earrings, you can’t help but admire their glow. Whether you’ve purchased your pearl jewelry or received it as a gift, it’s important to take care of it to ensure it lasts a lifetime.

Density of Pearl Jewelry

Diamonds, which have been compacted for eons deep in the earth, are the hardest gemstone in the earth. Pearls, on the other hand, are cultivated within the shells of oysters. These creatures of the water produce the nacre of the pearl, the lustrous coating that gives pearl jewelry its luminosity. Unlike diamonds, pearls are soft, so you want to take the steps necessary to keep these gems looking their best.

Pearl Jewelry Isn’t for Every Occasion

Although a simple gold wedding band will withstand the rigors involved in working with your hands, your pearl ring won’t. The same holds true for your pearl necklace and pearl earrings. So don’t wear your pearl jewelry when you engage in physical labor, work in the yard, or work out at the gym. The dirt and perspiration will shorten the life of your pearls. Similarly, even though the pearls come from the ocean, it doesn’t mean that your pearl jewelry will thrive when you swim in the ocean, surf, or scuba dive. Pearls certainly don’t have to be locked away and work only for special occasions, but you should take care that they aren’t damaged by the elements.

You may wonder what is the amazing thing behind Pearls? Well, Pearls are a complex object, to start the iridescence that pearls display is caused by the overlapping of successive layers, which breaks up light falling on the surface. In addition, pearls (especially freshwater pearls) can be dyed yellow, green, blue, brown, pink, purple, or black. I love Black Pearls, they are amazing.

This was the main reason why pearls fetched such extraordinary prices in the past. Imitation or fake pearls are also widely sold in inexpensive jewelry, but the quality of the iridescence is usually very poor, and generally speaking, fake pearls are usually quite easy to distinguish from the real thing.

You need to understand what sort of pearls you are buying, if you buy Pearls that come from Pearls farms you need to understand how they are picked up, these sort of pearls are carefully selected from long-established pearl farms. And then range in size from under 1mm to 20mm giants. Usually this farm pearls are harvested in the cooler winter months, after about two years of cultivation.

Like natural pearls, cultured pearls grow inside of a mollusk, but with human intervention. Cultured pearls are sold by their size in millimeters. Saltwater pearls originate within a saltwater mollusk. Saltwater pearls can be either natural or cultured.

Obviously it is not a surprise for anyone to understand that natural pearls are more expensive and if you are really interested in getting the best pearls in the world, well, you need to Travel all the way to Japan.
