Gemstone: South Sea Pearl
South Sea Pearls: Like all pearls, South Sea saltwater 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. South Sea saltwater pearls are beloved for their luster and in some cultures the traditional pearl (with its spherical shape) connotes the moon.
MOHs Hardness: 2.5-4.5
Origins: Saltwater farms in the South Pacific Ocean
Care: Keep 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.
