den07-24 - Cuprotungstite XLS on Scheelite - $ 950 SOLD Gold Hill District (Clifton District), Deep Creek Mts, Tooele Co., Utah, USA thumbnail, 2.0 x 1.8 x 1.6 cm ex. Philadelphia Academy of Natural Sciences ex. William Vaux
SHARP, definite crystals to 3 mm of the rare species Cuprotungstite are here perched atop an altering scheelite crystal (that is itself now partially Cuprotungstite ), on this amazing rare species piece from a very old US locality. Not much to look at, except dark green micros on a brown octo, but a very significant little treasure nonetheless. Sold by Cahn around WWI, judging by the address on his label.
MD-240579 - Cuprotungstite - - Archived Gamsberg, Khomas Region, Namibia small cabinet, 5.2 x 3.4 x 3 cm.
5.2 x 3.4 x 3 cm. A very fine specimen of the rare (for this location) Cuprotungstite. These clusters are composed of olive green tabular microcrystals. This is the first time I have seen this species even mentioned from Gamsberg. Often, Cuprotungstite is found after Scheelite, but since there is no Scheelite, I wonder if these exceptional pockets are primary. Either way, a strange locality for Cuprotungstite. Ex.
