Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/ab113c.jpg]

Stunning bi-color Tanzanite crystal of yellow over vivid purple/blue. This crystal has superb luster and unusually uniform shape, retaining an even 7mm thickness all the way from the base to the termination. There are two chips, including one on the back termination, but the sheer pizzaz and dramatic coloration greatly overcomes it, it's that pretty and unique. The best bi-color Tanzanite I've ever had. Weighs 13 grams.

Large, thick somewhat pinwheel formation of translucent yellow Brucite on a bit of matrix from recent finds in Pakistan. Undamaged and good from both sides, this is a very thick formation.
