Description

A nice specimen of beige-yellow powderized Bismutite with Beyerite, from the Meyer's Pegmatite, in Fremont County, Colorado.

The specimen comes with a copy ( not the original!) label from Eberhardt W. Heinrich (of Heinrichite fame).  The specimen was also in the collection of the University of Michigan Geology Department, as noted on the label

The measurements provided are for the micro centrifuge acrylic case

Note:  around 2007 the mineral Grayite was discovered to be at this mine, most likely associated with the minerals provided.  It may be present in the powder, but we could not determine for sure
