Calcite with Pyrite (ex. John Marshall)
stock #0292-JM-3826
Shullsburg, Lafayette County
Wisconsin, United States
9.4 x 6.8 CM (cabinet)
price: $240


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.
Azurite with minor Malachite
stock #4.2-539-.2
Tongshan Copper-Iron Mine, Guichi City
Anhui, China
7.4 x 6.7 CM (cabinet)
price: $140


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.
Smithsonite (Deep green, ex John Marshall Collection)
stock #0287-JM-455
Kelly Mine, Magdelena district
New Mexico, United States
9 x 6.6 CM (cabinet)
price: $875


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
