Well isolated Dioptase crystals to 8mm on white rhombic Calcite crystals. There is a second generation of Plancheite (?) or possibly tiny Calcite atop the Dioptase crystals. The label indicates that the mineral on the Dioptase is Plancheite.
ST567 - Prehnite with Graphite sold
Merelani Hills, Arusha, Tanzania
Miniature - 5 x 4 x 2.5 cm
Rare blue Prehnite crystal cluster from the Merelani Tanzanite mines. The blue Prehnite from this locality is far less common than the yellow and displays a color change (two different shades of blue) in indoor versus outdoor lighting. The Prehnite is undamaged though there are some cleaves of Calcite on the left side. This is a great example I've held onto for about 10 years or so and also has small Sphalerite, Diopside, and even a bit of Tanzanite attached, along with the black Graphite.

Miniature - 3.8 x 3 x 2 cm
