7idceis ((CYLINDRITE, BISMUTHINITE?)) $25 MINIMUM BID, Uncia, Bolivia, 9 x 6.5 x 5.5 cm, Cabinet, | |
Here is a specimen from the Philadelphia Academy of Natural Science. It is #20937 with the label. This has Bismuthinite written on the label. I am not sure if the specimen or majority of the specimen is Bismthinite but those round crystals are definitely great Cylindrite crystals rarely seen as such fine single standing crystals. They are not large probably 3 MM. ex Collectors Edge, ex Phila Academy, ex William Vaux |
