Pearls

The most coveted shape for a pearl is round -- perfectly round. And, as perfectly round pearls are as rare as totally unblemished ones, those that do exist command exorbitant prices. Usually, one finds pearls ranging from "all round" to "mostly round." With Tahitian pearls, which are extremely rare and expensive when discovered in perfectly round form, the industry standard for the average Tahitian pearl is termed, "slightly off round."

Pearl Colors

Mollusks create pearls in a palette of colors, from white to black and almost everything in between. Pearl color refers specifically to the color of the pearl's body, considered the fundamental color of the pearl.

Colors generally range from cream, to silver-white, to black. But there are also color overtones reflected across a pearl's surface. In fact, the color of a pearl more often than not is a meld of its body color and its overtone, just as the term "white-rose" will describe a white pearl with a rosy-colored hue.

Akoya Pearls

Akoya cultured pearls are white lustrous pearls with usually cream or rosé colored overtones. These are the classic pearls most often used in pearl strands. Classic Japanese Akoya cultured pearls come in shades of white, the most valuable shades being rosé and white. The other shades are white-rose, silver-white rose, greenish-white rose, and greenish-white.

Freshwater Pearls

Freshwater pearls come in various pastel shades of white, pink, peach, lavender, plum, purple, and tangerine.

South Sea Pearls

South Sea cultured pearls come in shades of lustrous white, often with silver or rosé overtones. They are larger in size than the Akoya pearl and are also used in the creation of fine pearl strands and ropes.

Black Pearls

Black pearls are known as Tahitian pearls, and come most often in shades of black and gray. While a Tahitian pearl has a black body color, it will vary in its overtones, which most often will be green or pink. Tahitian cultured pearls differ
from other pearls in one important respect. Yes, they are cultured, as opposed to natural -- but their black color is naturally produced by the oyster, which makes them "naturally black" cultured pearls.
