Akoya pearls, unless treated with dyes, are of neutral colors and tones. Most pearls range from white to gray in color, with secondary shades of pink, green, or silver. Sometimes some bluish with silver and pink hues appear, but these colors are extremely rare. Black Akoya pearls can also be found, thanks to radiation treatment with cobalt-60 or with an organic dye.

How is an Akoya pearl grown?

This shape, combined with the high brilliance of premium Akoya pearls, and their relative rarity compared to freshwater pearls, give Akoya pearls a higher perceived value.
