Balcoll Mine, Falset, Catalonia, Spain
Miniature, 5.0 x 3.1 x 2.8 cm
Partially etched out of massive white calcite, this plate of mostly brilliant silver is composed of spinel crystals, to .5 cm across. There are also a few matte black acanthite crystals, to .2 cm across, perched on silver. The overall effect is that of a hedgehog. Hefty specimen!
