Collection: Coral

Natural Coral Jewelry, Handmade in Japan

Explore TROZO's natural coral jewelry — handmade in Japan from real coral, chosen for its natural character rather than a uniform machine finish. Every piece is one of a kind.

Coral is one of humankind’s oldest organic gems — the polished calcareous skeleton of colonies of the soft-coral order, marine cnidarians. It is about 85–92% calcium carbonate (CaCO₃, mainly aragonite), 4–10% organic matter (the protein conchiolin and carotenoid pigment) and 1–3% water, soft at Mohs 3.5–4. Its history as a gem reaches back to 8000 BC. Japanese red coral (Corallium japonicum) is held the world’s finest, called “TOSA” by European buyers — the byword for beautiful red coral. It is March’s birthstone and the gift for a 35th “coral” wedding anniversary.

TROZO sets each coral so its natural colour and form lead the design — handmade in Japan, and no two pieces alike.
