Calcite over Stibnite
Quincy Mine, Hancock, Houghton County
7 x 5.2 x 6.2 CM (cabinet)
An odd, strangely attractive specimen with an interesting form, This is a series of fingerlike growths studded with scalenohedral calcite crystals. These have grown over slender crystals of Stibnite which are now completely covered by the reddish calcite. It is possible to see on the bottom where this was broken off the Stibnites remain.
A top quality example from a small recent (2008) find of rhombohedral calcites included by lustrous stibnite. A few of these were sold in Munich last year but nearly all had damage. We were fortunate to obtain at the source a few fine, esthetic and quite pristine pieces. There have been no more since. These are far more delicate and rare that the material found at Nandan in 1998, I expect these will also become modern classics and quite sought after. The glassy, tranlucent to transparent rhomb is 5.5 CM wide and has no eye visible damage. Magnification shows only a few rough spots on edges. The stibnites are clearly visible inside the calcite. Esthetic and displayable from several angles.
A fine gemmy calcite well included by shining Stibnites. A very good example from this important small find. The sharpness and clarity are excellent, and the calcite is the largest complete crystal I have seen from this find.

A single gemmy flattened rhomb sits on matrix and shows well the stibnites included and protruding from the crystal. Very sharp, nice color with no noticable damage but some very minor roughness to edges and contacts on back. Esthetic and eye catching!
