Gemstone: Tahitian Keshi Pearl
A Tahitian Keshi pearl is formed by accident, as a byproduct of cultured pearls—pearls from Tahiti are beloved for their grey to black hues. Keshi pearls are formed without a nucleus, so their shapes are skewed, organic, and pure nacre. Like all pearls, Keshi pearls are formed when an irritant becomes trapped in a mollusk. The mollusk secretes a fluid, called nacre, which coats the irritant layer upon layer until a pearl is formed.
MOHs Hardness: 2.5-4.5
Origins: Saltwater farms in Tahiti
Care: Keep Tahitian Keshi pearls away from chemicals. Contact with cosmetics, oils, acids, etc., can discolor or ruin the texture of pearls. To clean, use warm water with mild soap. Do not use an ultrasonic or steam cleaner. Strands of pearls should not be washed. They should be wiped down with a soft clean cloth before storing. Wetting the silk can cause stretching.
