A neat combination piece, thin platy caramel colored crystals of wulfenite to 1.5 cm across a set on this matrix that is mostly coated on all sides by white micro crystals of willemite. Crystallized calcite are scattered throughout. This is in good condition. The specimen comes with a previous label from the collection of Ray DeMark.The Erupcion Mine, located in the Los Lamentos mountains of Chihuahua, Mexico, was discovered and opened around 1920, with primary commercial operations winding down by the late 20th century though intermittent specimen recovery occurred later. Geologically, the mine consists of replacement deposits formed within Cretaceous limestone, where hydrothermal activity and subsequent oxidation led to rich secondary mineral zones. It is globally famous for producing world-class wulfenite specimens, characterized by thick, tabular, highly lustrous crystals with vibrant orange, yellow, and brown hues.
