2" Wulfenite & Botryoidal Mimetite - La Morita Mine, Mexico

 
 
 
This phenomenal specimen contains pristine orange wulfenite crystals that formed in association with yellow, botryoidal mimetite, collected from the La Morita Mine in Chihuahua, Mexico. The wulfenite crystals are in excellent condition and exhibit a wonderful silky luster. The botryoidal mimetite ranges from yellow to orange in color and is scattered throughout the specimen.

This is a high quality crystal association and would be an excellent addition to any mineral collection.

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, with coloring 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 their being lead based, washing your hands following handling is strongly suggested.

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're typically found associated with each other. Regularly ranging between red and 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.
