Collection: Zircon

Raw Zircon Jewelry, Handmade in Japan

Explore TROZO's raw zircon rings — each built around a real, uncut zircon 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.

Zircon (ZrSiO₄) is a zirconium silicate, tetragonal, Mohs 7.5. It comes in many colors — colorless, blue, yellow, red, brown, green — and blue zircon is the most popular, making up about 80% of the market. Zircon is special because it is the oldest mineral found on Earth: grains from Jack Hills in Western Australia are about 4.4 billion years old. It is entirely different from synthetic cubic zirconia (ZrO₂), and a modern December birthstone.

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