20hhgd.is ((VESZELYITE, QUARTZ with probably DUFTITE coating)), Pictured on mindat.org $35 MINIMUM BID, Black Pine Mine, Philipsburg Mining District, Granite Co., Montana, USA, 3 x 2 x 1 cm, Thumbnail | |
I accidently cropped the full specimen pic. This is a Lavinsky specimen pictured on mindat.org with the description of a very rare copper, zinc phosphate species with the best specimens from the Black Pine Mine. Description further states it is an extremely rare combination with Veszelytite and Quartz with a copper oxide coating. I think it is probably Duftite. The blue Veszelyite crystals are small 1 to 2 MM double terminated bowtie shaped crystal clusters. ex Glenn Davidson collection |
