2.9 x 1.8 x 1.1 cm. Aikinite is a relatively uncommon lead, copper, bismuth sulfosalt. This representative toenail is richly covered with metallic-bright, lead-gray, layered sheets of aikinite microcrystals and is from the much less common for the species Nevada locality of Cucomungo Spring in Esmeralda County. Ex. Carl Davis Collection.

Aikinite with bismutite on quartz. Associated minerals, not in the photograph, include, conichalcite, connellite, gold, kettnerite, and mixite. This specimen has not been analzyed. The identification is based on the associated minerals. I collected this specimen from the 30' level of the mine. Brent Thorne specimen and photograph.

These crystals reach about 0.75 mm. Only two specimens were found, the opposite sides of a cavity. ID via Tony Kampf. This specimen is in the possession of the Los Angeles County Museum, CA. The other specimen was lost by a different mineralogist, so this is the only known specimen of aikinite from the Sweet Home.

5.2 x 2.3 x 2.3 cm. Aikinite is a relatively uncommon lead, copper, bismuth sulfosalt. It is very rare from this obscure molybdenum mine, where specimens of any species are rare.

Although this metallic grey crystal looks single-phase, SEM-EDS analyses of an adjacent, visually identical crystal revealed a microscopic intergrowths of aikinite (chemically pure) and bismuthinite partly containing trace amounts of Cu, Sb and/or As. These two minerals and the accompanying, fine-grained chalcopyrite are grown on a thin fissure in ...

Aikinite crystals (blackish-silver) and orthoclase pseudomorphs after aikinite (dull greenish) in massive quartz. The aikinite crystals are often partly (or sometimes, completely) altered to orthoclase which is tinted slightly greenish, probably due to traces of copper from the aikinite. Raman analysis and a separate SEM scan show the altered ...
