Gowerite - Sold

Gowerite is a rare calcium borate formed by alteration of colemanite and priceite. Erd et al. (1959) originally described the mineral from several localities in Death Valley, also remarking that this locality (Hard Scramble) produced the best specimens. The mineral name honors Harrison P. Gower (1860-1967), manager at the U.S. Borax Corporation. This is very rich in gowerite, with needles to 2 mm, forming radiating clusters. This specimen is friable and fragile, but with careful packaging should ship without issue. There is minor gypsum present. Quite rare!
