Nissonite - Sold


Nissonite is a hydrated copper magnesium phosphate. Mrose et al. (1966) named the mineral in honor of William H. Nisson (1912-1965), amateur mineralogist and mineral collector of Petaluma, California, USA, who found the mineral and recognized its unusual chemistry by micro-chemical testing. This specimen consists of a schistose rock, with a coverage of sparkly green-blue microcrystals.

This specimen was part of the personal collection of Ralph Merrill, proprietor of the prolific mail order business Minerals Unlimited. Merrill obtained the piece from a co-author of original description, John Alfors, in 1967. Merrill's collection card and label ship with the specimen.
