It comes from Siberia, the only place in the world it's found, near the river Chari. These earrings are set in sterling silver, in a setting hand made by our jewelers for your enjoyment. 4 cm long. Wonderful Shades of Purple mixed with White Chatoyant lines that shimmer and "move" when held in the light.
