Brandburg quartz - double terminated smoky quartz twinned crystal, with excellent skeletal layering to faces and terminations. One termination is very good, the other is incomplete and shows key features where it has been extracted from groundmass. One half of the crystal is of excellent clarity with visible layering within, which reveals a very small double terminated manifestation crystal. The crystal also has many small air bubbles within and lots of darker areas of singeing, which are classic for its type.
