AU867 - Feldspar var. Moonstone sold
Namalulu, Tanzania
Small Cabinet - 8.5 x 3.5 x 3 cm
New find of crystallized moonstone from Tanzania. Individual crystals to 5cm that display a satiny blue color when turned under lighting. This 'Schiller effect' of color is seen at different angles on the different crystals. These have been found here in the past, but this new find has much higher quality, porcelain-like lustrous crystals than those found previously. Moonstone crystals are rare!
