Pearls

Mystique of the ocean.

A pearl is one of the few precious gems that come from a living organism. From a grain of sand or a mother-of-pearl bead within an oyster, pearls are born from the patient accumulation of nacre layers. Carson Jewelers offers pearls in a variety of sizes, shapes and colors. Some of the basic varieties include Akoya cultured saltwater pearl, freshwater cultured pearls, South Sea cultured pearl and Tahitian Black cultured pearls.

Most pearls are graded based upon size, color, shape, luster, nacre, number of blemishes, and matching. When judging pearls, it is best to lay them on a light (white or gray) color background and compare strands or individual pearls with each other.

Size

The size of the pearl is determined largely by the size of the implanted nucleus. All other things being equal, the larger the size the more rare and valuable the pearl. South Sea and Tahitian Black pearls are known for their large size ranging usually from 10 to 19mm. Akoya cultured pearls tend to be 10mm or smaller.

Color

Pearls come in a variety of colors including white, cream, pink, yellow, gold and black. Cultured pearls often have a secondary color referred to as overtone, which is traditionally rose or green in Akoya pearls and pink, blue, green, silver or gold in Tahitian black pearls. Generally speaking, Akoya pearls with a silver-white body color and rose overtone are most prized.

Shape

Perfectly round pearls are rare. The shape of a pearl can range from baroque, which is very asymmetrical, to round. The more round the pearl the greater the value, all other things being equal.

Luster and Nacre

Luster refers to how well the light reflects from a pearl back to the eye. The sharper the reflection the higher the luster. The luster depends primarily upon the thickness and the quality of the nacre. The oyster in colored waters produces higher luster. Also the longer the pearl is left in the oyster, the thicker the nacre. All other things being equal, the higher the luster the greater the value.

Number of blemishes

This refers to the quality of the surface of the pearl. Small pits and imperfections on the surface are referred to as blemishes. They can be best examined by rotating the pearl slightly. The fewer number of blemishes the higher the value.

Matching

A strand of pearls is valued based in part upon how well the pearls are matched with respect to the attributes listed above. It is important that the pearls are well matched in terms of size, color, shape, luster and blemish.
