Natural Amblygonite

Amblygonite is a collector stone occasionally clean enough to be faceted. The most important sources for amblygonite are the deposits in Sao Paulo and Minas Gerais, Brazil. Amblygonite forms in large rough triclinic crystals with a tabular habit and perfect basal cleavage. The mineral is a fluophosphate which like topaz, has the fluorine replaceable by the hydroxyl group.
