This sample has, for me, both a collection and scientific interest. It is a sample of cinnabar "veins" in its host rock, which has been perfectly polished to be able to see the structures of this breccia. Intense red colors of cinnabar snaking between fragments of quartzite impregnated with cinnabar, isolated crystals of pyrite and veins of dolomite. A true curiosity from Almaden to study under the magnifying glass.
