Collection: Tourmaline

Raw Tourmaline Jewelry, Handmade in Japan

Explore TROZO's raw tourmaline necklaces, rings, ear cuffs, earrings and bracelets — each built around a real, uncut tourmaline rather than a cut and polished stone. Many are set in sterling silver. Every piece is handmade in Japan, and as one-of-a-kind raw stone it is truly unique.

Tourmaline is a group of more than fifteen minerals. The representative elbaite is Na(Li,Al)₃Al₆(BO₃)₃Si₆O₁₈(OH)₄, trigonal, Mohs 7–7.5. Its great distinction is the widest range of color of any gem — from colorless to black, with two colors (bicolor) or three (party-color) in a single crystal, and the pink-center, green-rim “watermelon”. Paraíba tourmaline, found in Brazil in 1989, is one of the world’s three rarest gems. It is October’s birthstone (with opal).

TROZO works every tourmaline unpolished, setting it so its natural colour and form lead the design — handmade in Japan, and no two raw stones alike.
