Description
Coral is an organic gem, composed of the external skeletons of coral polyps. Formed from calcium carbonate with no crystal structure, coral has been prized in jewelry for over 30,000 years — from prehistoric times to the present day. Today, supply is limited due to pollution and environmental protection efforts, making quality coral increasingly rare and valuable.
This Alaskan Gem Coral is sourced from deep cold water tree coral found 1,000 meters below the surface in the Gulf of Alaska. Classified as aragonite, this coral is cut and polished in the USA with no treatments applied, offering jewelers and metalsmiths a genuinely natural, untreated material for high-end jewelry design and resale.
Due to its natural softness, coral should be worn and handled with care. Avoid exposure to chemicals, heat, and abrasion. Clean only with warm, soapy water. Do not use ultrasonic or steam cleaners.
