K463 - Prehnite SOLD Merelani Hills, Arusha, Tanzania miniature - 4.5 x 4 x 3.5 cm Rosette shaped group of translucent yellow Prehnite crystals. Great color and large crystals, this is one of the finest specimens from a large lot of recently mined and purchased Prehnite specimens from the Merelani Tanzanite mines. The main rosette is 4cm tall and sits nearly vertically for display. The larger crystals appear to have grown from a central sphere of Prehnite. The bottom is somewhat flat where it grew against Graphite. It's pristine except for light chipping on some crystals and a contacted backside. ©2010-2018 Marin Mineral |
