This beautiful stone comes from a mine located in Central America. Likely Honduras.
Please view all of the pictures. I have noted what kind of light I am using in three of the photographs. The stone looks its best in bright light. In low light it has less fire but the purple base color shows more prominently.
There is also a video below, shot using high indoor lighting.
The back of the stone still has some host rock attached. This would be sanded smooth before setting in jewelry.
