Brandburg quartz - an interesting clear quartz formation comprising 3 main crystals with additional drusy crystals and some groundmass. The main crystal is a double terminated self healed crystal with a window face: one end of the crystal is much smaller than the other, where a pair of bridge crystals grow out of the side near the self healed markings. All the crystals are of good clarity and have good terminations.
