Bunker Hill Mine, Kellogg, Coeur d’Alene District, Shoshone County, Idaho, USA
In the mid 1990s, Bunker Hill in Idaho produced a pocket of unique pyromorphites. The rounded, botryoidal crystals ranged from yellow to orange to a deep sienna color. The very best of these had a shining, wet appearing luster. Chemical analysis showed the tan to yellow crystal were polysphaerite – a calcium bearing variety of pyromorphite. The darker orange crystals were found to be arsenian pyromorphites. This specimen has an extremely intense wet and silky luster with both the yellow and orange crystals well represented. The plate is well balanced with the darker crystals in the center giving way to the lighter yellow crystals on the edges. The piece is in good condition with minor wear at the plate edges and great coverage of matrix with gorgeous crystals.
