This beautiful polished stone necklace appears to be Charoite from the research that I've done. The necklace is cold to the touch and the stone has many different colors, purple, orange, white, blue, and cream swirled into it. It has a 925 lobster clasp closure. This necklace is approximately 14 1/2 " inches long. It is a very small choker style necklace. -Charoite Choker style necklace -approximately 14 1/2" in long -925 lobster clasp closure -please check measurements as this is a very small choker style necklace -pre-owned condition
