- Tanzanite with Prehnite on Calcite
- Large Cabinet, 18.0 x 15.0 x 11.0 cm
- Block D, Merelani Hills, Arusha Region, Tanzania
The photos tell the story here, but for a bit of context: Few large matrix tanzanites exist, particularly in this size. The single crystal is 17 cm tall and perched in calcite. It is an astonishing and rare example of tanzanite with unusual pseudocubic crystals of prehnite, just as a bonus to the huge impact of the intense blue tanzanite crystals themselves. No repairs or damage. Truly a "major national museum specimen," for the display impact, if ever there was one. The piece weighs 6.6 pounds. From a private collection. Comes with custom base, Joe Budd photos.
