Nice specimen of glassy Fluorapatite crystals from the famous Panasqueira mine. Displays tabular crystals to 7mm. They are colorless with light green hue and vitreous luster. Fluorapatites are hexagons, transparent and gem. Some Muscovite is seen too. The base is formed by lustrous Arsenopyrite, seen on the back side.  For references see the 2014 issue of The Mineralogical Record vol. 45, # 1. In good condition – some nicks and contacts.

Perfect Fluorapatite!
