1.55" Epidote Crystal Fan with Adularia - Pakistan

This is a cluster of dark green epidote crystals in a fan shaped aggregation that's associated with white adularia crystals. The specimen was collected from Balochistan, Pakistan.

Epidote is a green, silicate mineral that is commonly found in regionally metamorphosed rocks. It often forms lustrous, elongated and interconnected crystals that are highly coveted by collectors. While nearly all epidote is green it may take on many different shades and tones from yellowish to deep green.

Adularia is a variety of feldspar that had the chemical formula KAlSi3O8. It's found most often as colorless to white aggregations within metamorphic rock, with one example being formation within cavities of crystalline schists. The crystals are commonly twinned, glassy and prismatic in structure, and in some cases they display opalescent characteristics. Adularia is very similar to orthoclase, even baring the same chemical formula, however it has a different crystalline structure and reacts differently to various tests.
