Classic calcite on sulfide and dolomite matrix from the great discoveries at Shullsburg. Esthetic and well presented, the calcites reach 3.2 CM. The backside isalso displayable. The front display face appears damage free (magnification finds micro nicks)there is contacting on the reverse but all in all it looks pristine. These are well respected as great and distinctive specimens, this is a good affordable example.
A big, bright blue sparkling specimen with Azurite crystals densely packed on the display faces. The copper deposits in this area of Anhui province have been mined for thousands of years, probably the longest continuous operation on earth. Small scale mining lets specimens escape the huge crushers that are used elsewhere. Very attractive and affordable.
Super deep rich color, no damage and large size from mining in the late 1950's. These are already cherished classics for their color and luster. Much more green than the usual blue color, displays well and a very good value
