Description

An excellent floater! The crystal is highly lustrous and attachted to a thin plate of matrix. Tiny sparkling quartz crystals are scattered on this matrix. Chlorite inclusions and a layer of Chlorite backside are responsible for the dark green color and for the amazing phantoms. The main crystal is waterclear, you see the chlorite on the backside and the matrix underneath. Hard to photograph, much better in person and undamaged.
