Description

A doubly terminated quartz crystal with a thicker and a second crystal on the side. The crystal is full of tourmaline inclusions and has a vividly textured face. That's the reason why the quartz is so dark. The single enclosed crystals are clearly visible and also grown on the faces. An undamaged, doubly terminated floater quartz with respectable size and interesting inclusions!
