The akoya pearl is a saltwater cultured pearl from the akoya oyster (Pinctada fucata martensii).

Akoya are considered to be the classic pearl used for necklaces and other pearl jewelry,

with perfect round shapes, bright mirror-like luster and neutral colors.

An interesting piece of akoya pearl trivia is that the akoya oyster is the smallest commercially farmed, pearl-producing oyster.

An average akoya pearl is only 7 mm, while an average South Sea pearl is in the 12 mm range.

Akoya pearls are currently being harvested in sizes from as small as 1 mm

up to the very rare 10-11 mm. pearls, unless color-treated, have neutral colors and overtones.

Most pearls are white to grey, with pink, green, or silver overtones.

Occasionally, akoya pearls are blue with silver and pink overtones, but these colors are extremely rare.
