Quartz var. Smoky Quartz

A superb, ex-matrix, single crystal of Smoky Quartz from the Grimsel area in the Hasli Valley, Bern, Switzerland. To one side of the base, the first 2.3 cm is partly included with opaque chloritic and granular milky Quartz, remnants of the former matrix. At the opposite side, one prism face extends 7.3 cm to the full length of the specimen. Apart from the odd hair-like internal filament, the crystal is perfectly transparent and of a completely uniform mid-clove brown. Its optical clarity is superb, resulting in the ability to read very small print through any two opposite faces with great ease.
