This specimen is a rarity, as it is a crust of meisserite with minor bluelizardite on a matrix of coalized wood and uraninite. 
After inheriting some unidentified vintage collection pieces, this one called out to me when examining it under the microscope, so I had it tested. 
Both of these minerals have Blue Lizard Mine as their Type Locality and are very rare with only this ONE location in the entire world!! It does not get rarer than that. This is a very good size and a well-presented specimen.
