Fluorite, Quartz, Schorl and Muscovite Crystals on Matrix – NERF 037

Fluorite, quartz, schorl and mica crystals on matrix





Measurements:  52 x 36 x 30 mm

Description:  Small, green fluorite crystals share a schorl and mica matrix with quartz, small schorl and muscovite crystals. Some of the quartz crystals have schorl crystal inclusions. 

The largest quartz crystal has a nick close to the termination point, along one of the termination ridges. Some of the fluorite crystals have damage to their edges.

The specimen displays well on a flat surface, with all around being display sides.
