Description

A doubly terminated quartz crystal with a thicker and a thinner termination. The crystal is clear in the upper part; the lower part is full with tourmaline inclusions. That's why the quartz is so dark. The single enclosed crystals are clearly visible. An undamaged, doubly terminated floater quartz with respectable size and interesting inclusions!
