Phlogopite Mica (rare gemmy crystals)

Item Description

Excellent example of the fine, lustrous Phlogopite crystals found in the marbles of Pein-Pyit in Myanmar (previously Burma). The sharp, pseudo-hexagonal, gemmy, golden-brown crystals are set aesthetically in white marble, and the contrast in color is quite attractive. Such gemmy ,translucent crystals are rare for any mica species, particularly from Burma. Old material, from the 1990s or ealry 2000s. The largest crystal reaches 1.9 cm and, with just the right lighting, the gemmy crystals glow and you can see deep down almost to the matrix. Excellent and uncommon material from this locality. For reference, see the 2001 issue of The Mineralogical Record, Vol. 32, # 1, and Volume 53, #1. Formerly in the extensive collection of W & A Cook.
