The relatively rare pyramidal or "4 sided pointed chisel tip" termination is well displayed on this stibnite and the matrix is almost pure cubic Fluorite included by stibnite. Some stibnites display a brassy and blue irridescent alterations. The largest crystals are perfect but there is minor damage elsewhere and a broken stib near the center that can be seen depending on the angle of display. That said it is still very displayable, esthetic and shows a rarer crystal form and a great association.
Stibnite and Barite
Dehegou Mine, (Zhangergou, Lushi) Lushi County
An outrageous mineral! A large Stibnite (12 cm long, crudely terminated)) grows through a large sharp translucent to transparent rhomb of Barite. Stibnite is coated in part with alteration minerals (probably Stibiconite or Valentinite) that add a color contrast. Impressive from many angles, the Stibnite has some dings on one edge that can be hidden depending on the angle selected for display. This is a truly fine piece!
