Item Description

Silver globules, some crudely crystallized, are richly and dramatically visible on both sides of the large sawed and polished slab of the mostly dolomite matrix. Rich and shiny patterned silver ore. Specimens of this richness and sculptural quality are rare from this less well-known old extinct New Mexico silver mine. Mass is 109 grams. Classic and very seldom available material from the collection of New Mexico specialist Chris Cowan.
