Collection: Spinel

Raw Spinel Jewelry, Handmade in Japan

Explore TROZO's raw spinel jewelry — each built around a real, uncut spinel rather than a cut and polished stone. Every piece is handmade in Japan, and as one-of-a-kind raw stone it is truly unique.

Spinel (MgAl₂O₄) is an oxide mineral, isometric (cubic), Mohs 8. Its colors span red, pink, purple, blue, green, yellow, brown, colorless and black, and red spinel was long confused with ruby. Until the French crystallographer Romé de l’Isle distinguished it from ruby in 1783, many of the world’s royal “red gems” were in fact spinel — including the 140 ct Black Prince’s Ruby and the 361 ct Timur Ruby. It is a modern August birthstone.

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