Charoite

Murun mountains, Siberia, Russia

A rare purple stone with swirling marbled grain, found in only one place on Earth.

Where it comes from

Charoite is mined exclusively from a small region in the Murun mountains of eastern Siberia. It was only formally identified as a distinct mineral in 1978, which makes it one of the youngest named stones in jewelry circulation. The single-source geography means total global supply is limited.

What makes it distinctive

A complex silicate with vivid lavender to deep purple coloring and a distinctive fibrous, swirling grain. Patterns often look like brushstrokes or wind-blown marble. Not turquoise, but striking in jewelry where purple complements sterling silver or pairs with turquoise for color contrast.

How to identify it

Look for the unmistakable purple swirl. No other stone in commercial jewelry rough has charoite's specific fibrous patterning. Hardness sits around Mohs 5 to 6, so charoite is best in earrings, pendants, and protected settings rather than rings or cuffs that take heavy daily wear.
