Sunstone

Raw Sunstone Jewelry, Handmade in Japan

Explore TROZO's raw sunstone rings and ear cuffs — each built around a real, uncut sunstone 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.

Sunstone (also heliolite) is the name for plagioclase feldspars that hold flakes of metal or oxide minerals and throw a metallic flash with the angle of light. Triclinic, Mohs 6–6.5. Its flash, “aventurescence (schiller)”, comes from aligned platelets — native copper (Cu) or hematite — reflecting incoming light specularly. Oregon sunstone, named Oregon’s state gemstone in 1987, holds native copper plates in labradorite formed in basalt. It is the feldspar-group counterpart to moonstone — “sun” to its “moon”.

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