Fluorite (M969)
China
LOCATION
Yaogangxian, Hunan, China
SIZE
67 x 44 x 42 mm
DESCRIPTION
The main crystal is 31 mm across, it is complete and well developed all around. The matrix is Quartz coveredd with tiny Muscovite crystals and some micro crystals of Pyrite. It is from Yaogangxian and from Yaogangxian we know sharp terminated cubes, no rhombs at all. Only from Shangbao we know the combination of cube and rhomb, but also co complete rhombs. The habit of this crystal is almost unique for the locality and even for entire China, which really produce lot of Fluorite. In fact - the only other locality I know, that produce almost complete rhombic Fluorite crystals is Dalnegrosk. The only thing which is still part of the cubic habit is a tiny face - not even 1 mm on edges - at each end-point. Ex Robert Brandstätter coll.
