This is charoite in an 10mm round cabochon. In the past I've stocked this and it's been hard to find nice quality, well-cut, well-polished material - I've sold this by having my own ones cut, and very nice they are too. Lovely purple striations with the occasional areas of chatoyancy. A gorgeous stone with a limited supply that is likely to become harder and harder to find.
