Iolite

Raw Iolite Jewelry, Handmade in Japan

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

Iolite (cordierite) is a magnesium-aluminium silicate, Mg₂Al₃(AlSi₅O₁₈), orthorhombic, Mohs 7–7.5. Its great distinction is very strong pleochroism — the color shifts clearly with the angle, from deep blue-violet to gray to pale yellow-brown. Its other name “dichroite” reflects this, and “water sapphire” its sapphire-like blue. With a legend that Vikings used it as a “sunstone” to find the sun through cloud, it is a modern March birthstone.

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