Item Description

An excellent small cabinet combination from this well-known extinct As-Cu-Au-Pb-Ag-Zn-W-Ba (baryte) mine, closed in 1945. This is an important, large, display quality specimen from the locality. This mine is famous for an assemblage of secondary minerals of copper and other metals (MINDAT). Green-yellow, translucent, adamite botryoids and botryoid sections are aesthetically set in the sculptural vug on the sturdy gossan matrix. The large botryoid is 1.7 cm across. Striking sprays of glassy Austinite spikes are artistically set on the adamite botryoids as a fine contrast and complement. Lime-green adamite fluorescence under both LW (stronger) and SW (fainter) UV light. The piece displays beautifully without aid. Ex Chet Lemanski Collection No. 01559CL and acquired in 1989. His label says the colorless spikes are Calcite, but we believe they are Austinite after reviewing MINDAT and confirming it doesn't fluoresce. This is an educated guess but, after all, the Gold Hill Mine is the Type Locality for Austinite. Fine and uncommon adamite, with the bonus association of colorless austinite, from Gold Hill.
