Prehnite -well crystalized
stock #18.1-587
Merelani, Umba Valley, Lelatama Mountains, Arusha Region
Manyara Region, Tanzania
5.7 x 3.9 x 3.2 CM (cabinet)
price: $300
Dec 2018

Radiating cluster of fine terminated Prehnite crystals from the famed Merelani Hills best known for its Tanzanite. In fine condition by naked eye, some very minor bruising is seen with magnification, but overall the visual impression is pristine. This is also a color-changing Prehnite and can look green to a gray-blue depending on the light source. Some of the crystals also show slight rotation or twisting like some of the classic European Alpine specimens.
Diopside on Graphite
stock #17.1-885
Merelani, Umba Valley, Lelatama Mountains, Arusha Region
Manyara Region, Tanzania
2.9 x 2.2 x 2.3 CM (small miniature/ large thumbnail (toenail))
price: $390
Pre Holiday 2017

The gem Diopside crystals from Merlani are modern classics and can have brilliant form as seen here. The color is a yellow to pale greenish hue and the crystals are complete all around, undamaged and statuesque. The contrast with the Graphite adds a nice balance and the complex modified terminations are very distinctive. Good luster with gem clear areas but more translucent than transparent overall.
Dravite (unusual gem clear crystal)
stock #14.1-049
Namalulu, Simanjiro District
Manyara Region, Tanzania
3.8 x 1.1 x .8 CM (miniature)
price: $340


From recent finds of Dravite in Tanzania, this is a very sharp, lustrous and surprisingly gemmy single crystal. Deep red brown color in excellent condition this glows with a backlight, in normal lighting it looks darker, more like the photos shown here.
