Bi-Pyramidal Wulfenite with Green Mimetite - Mexico

This specimen contains pristine orange, bi-pyramidal wulfenite crystals, protruding from matrix containing green, botryoidal mimetite, collected from the Qjuela Mine in Mapimi, Mexico. The green mimetite can be found between wulfenite terminations, as well as imbedded within the matrix.

This specimen comes with an acrylic display stand.

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.
