(ARA) – Diamonds may get the credit for being “a girl’s best friend,” but humanity’s love affair with pearls has been going on for 4,000 years -- about a millennium longer than we’ve been digging diamonds out of the dirt.
What’s more, pearls are the only “green” natural gemstone; they are a renewable resource and are harvested, rather than mined. And consider what it says about Americans’ vision of exemplary womanhood that June Cleaver and other iconic pop culture moms wore strands of pearls, not drapes of diamonds.
While you may have heard about the basics of diamond buying, few consumers are as educated about the nuances of pearl purchasing.
“As with any other purchase, consumers should educate themselves before buying pearls,” says Jeremy Shepherd of PearlParadise.com. “Knowledge can mean the difference between buying a lackluster strand of overpriced imitations and getting quality pearls at competitive prices.”
Before you buy pearls, here’s what you should know:
Types and Sources of Pearls
Four types of pearls are available today and they come from all over the world.
* Freshwater pearls, known for their off-round shapes, fancy colors and affordability, are almost exclusively produced in China. Prices range from as little as $20 for a strand of low-grade freshwater pearls up to several thousands for gem-grade freshadama pearls.
* First cultured and sold in Japan nearly 100 years ago, akoya pearls are the type most people think of when talking about pearls. While China and Japan are the two largest producers of akoya pearls, Vietnam, Korea and Australia also produce limited quantities.
* Although they’re also known as “black pearls,” Tahitian pearls actually come in every color of the rainbow. They are prized for their large size and exotic colors. The Tahitian Islands are the main producers, but some production also occurs in the Cook Islands, Fiji, Micronesia and parts of southern Japan.
* The most valuable of all cultured pearls, South Sea pearls are renowned for their large size and satiny luster. A large perfect strand of these white, golden or silver pearls can cost millions of dollars. Australia is the primary producer of the white and silver pearls, while the Philippines and Indonesia produce golden pearls.
How to Evaluate a Pearl’s Quality
Just as you would look at the clarity, cut and carat of a diamond to determine its worth, pearls have value indicators as well. They are: luster, surface, nacre, matching, color and shape.
* Luster – When dealers price pearls, the single most important factor in their decision is the luster. Pearls should have a sharp, reflective quality. You should be able to see your reflection in a high-quality strand of pearls.
* Surface – The pearls should be free of marks, abrasions, cracks, pits or any other imperfections that mar the surface of the gemstone.
* Nacre – The thickness of the nacre – the “coating” of pearl that surrounds the bead that was inserted into the oyster – is important when dealing with saltwater pearls, especially akoya pearls. If the coating is too thin, the pearls will be chalky and will not last more than a few months to a year. If the pearls are chalky, or you can see a bead through the surface, the nacre is too thin.
* Matching – Whether you are buying a strand of pearls, a pair of earrings, a bracelet or an earring and necklace set, each pearl in the set should match in size, color and luster. For a set of earrings, the size should match within a tenth of a millimeter; for strands, pearls should match in size between half a millimeter to two millimeters. If you’re buying a strand, the pearls should also be matched from either side of the strand as it drapes.
* Color – Another important value factor, color is heavily dependent on preference. While classic white pearls will always be prized, some colors are more commonly preferred than others, such as peacock-color Tahitian pearls or rose-overtone akoya. These colors will often cost more than others.
* Shape - Pearls come in many different shapes, from wings and potato to rice crispie (or baroque) and round. The more perfectly round a pearl is, the more valuable the strand is if all other value factors are equal.

The ‘Green’ Gemstone
(ARA) – When you think of “green” gems, do emeralds come to mind? Think again.
“Pearls are the only truly ‘green’ gemstone in that harvesting them has far less negative environmental impact than mining other stones,” says Jeremy Shepherd of PearlParadise.com. “Saltwater pearl farms’ success depends on the preservation of a pristine environment. Farmers grow their own oysters and are responsible for the preservation of many different species, some of which were on the verge of extinction before pearl farming began.”
“Their sustainable harvesting practices could be one reason why pearls are riding a popularity wave unlike any in the history of the gem,” Shepherd says. “Pearl prices in general have dropped enough to make pearls affordable for all ranges of income. The variety of colors, shapes, sizes, styles and price points mean you can find pearls to match virtually any taste or wardrobe.”
