Feldspar var. Moonstone from Namalulu, Tanzania [db_pics/pics/J810e.jpg]

Blocky, grey/white Felspar crystals from a recent (and seemingly one time) find of crystallized moonstone from Tanzania. This is the single best specimen I've seen with both quality, well formed crystals and good color. The main crystal is 4.1cm wide and displays a satiny blue color across the end surfaces. This 'Schiller effect' is seen when you turn the crystal under lighting. Good color can be seen on a number of the other smaller crystals too. Moonstone crystals are rare!
