Description
Blue Quartz is probably the rarest variety of this species and the deep blue color is caused by inclusions of Magnesioriebeckite. And here we have nice and highly lustrous, slightly deformed crystals up to 0,7 cm. Good material is now rarely offered because the site no longer produces good pieces. This locality has been known since the late 18th century. Located in the upper Grabenbach valley, about 5 km NE of Golling.
