About Tortoiseshell
Tortoiseshell is an organic gem material derived from the scutes (plates) of the hawksbill sea turtle, displaying a warm translucent amber to brown base mottled with darker brown and black patterns that have been prized for decorative use since ancient Rome. Once extensively used for combs, hairpins, eyeglass frames, jewelry, and inlay work, the trade in natural tortoiseshell is now banned worldwide under CITES as the hawksbill turtle is critically endangered. Modern 'tortoiseshell' items are made from acetate or synthetic resins.
