Feldspar var. Moonstone (Ref: P610)

Namalulu, Tanzania
35mm x 30mm x 25mm
$500
Miniature sized specimen of crystallized moonstone from Tanzania. Individual crystals to 2.5cm that display a satiny blue color when turned under lighting. This 'Schiller effect' of color is seen at different angles on the different crystals and was therefore not possible to catch in still photos and these are therefore more colorful and attractive in person. Moonstone crystals are rare! Though not the largest, this was the finest quality example from a find approx. 10 years ago.
Data last checked on 18th Oct 2025 - specimen may no longer be available
