For nearly 100 years, akoya pearls grown off the coast of Japan have been the classic pearl of choice. When one pictures a round strand of white pearls, they are usually thinking of akoya.
Although rare baroque shapes and natural colors like silver-blue and gold do exist, akoya pearls are best known for their perfectly round shape and sharp, reflective luster.
While exceptions do exist, most akoya pearls produced today range in sizes from 4 to 10 mm.
If you are looking for a classic strand of round, white pearls, you are probably looking for a strand of akoya pearls.

Selecting a Pearl
One of the most important considerations in selecting a piece of pearl jewelry is determining the type of pearl that is best suited to your budget and preference. There are two basic varieties of cultured pearls; freshwater and saltwater. Freshwater pearls are grown primarily in man-made lakes and reservoirs in China. Saltwater pearls, which include akoya, Tahitian and South Sea, are grown in bays, inlets and atolls in many places around the world. Saltwater pearls are considered more valuable than freshwater pearls, although rare and very high-quality freshwater pearls can be exceedingly valuable.
Pearl grading is one of the most difficult aspects of pearl selection to understand. There is no officially recognized, standard system for grading pearls, except in the case of Tahitian pearls, where grading and export is controlled by the French Polynesian government. For that reason, it is important to understand the grading used by the company from which you purchase. A detailed explanation of luster, surface, shape and color is necessary to make an educated purchase decision.
