1.8" Orange Hexagonal Mimetite Crystal Cluster - Thailand
This is a cluster of small yellow-orange hexagonal mimetite crystals on rock from the Guatomo Mine of the Yala Province in Thailand. This specimen comes with an acrylic display case for presentation.
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.
