2.8" Orange Wulfenite and Botryoidal Mimetite - La Morita Mine, Mexico
This is a gorgeous formation of orange wulfenite crystals and botryoidal mimetite on matrix, collected from the La Morita Mine in Chihuahua, Mexico. The wulfenite crystals exhibit a wonderful luster. The largest crystal is .5" wide and the entire specimen measures 2.8 x 1.7".
Wulfenite is a lead-based molybdate mineral with a chemical formula Pb(MoO4). It forms as a secondary mineral in the oxidation zones of hydrothermal lead deposits, its color ranging anywhere between yellow to bright orange and red and occasionally brown. Typically forming as tabular, stubby, or pyramidal crystals, this unique mineral can be both brilliantly transparent and opaque.
While these crystals are safe to hold, due to the fact that they are lead-based we strongly recommend washing your hands after handling.

Mimetite is a lead chloro-arsenate mineral with the chemical formula of Pb5(AsO4)3Cl. Depending on conditions during formation/replacement, arsenate radicals (As04) can be replaced by a phosphate (PO4) or vanadate (VO4) radical. This alteration is what leads to the formation of pyromorphite and vanadinite, hence why they are typically found associated with each other. Often red to yellow in color, mimetite can occur in a variety of structures, from small prismatic clusters and crusts to incredible hexagonal crystals both thick and thin.
