1.3" Bright Orange Wulfenite and Mimetite Cluster - Rowley Mine, AZ

This is a cluster of small, bright orange Wulfenite crystals on matrix from the Rowley Mine in Arizona. The specimen is 1.3 x 0.8" in size, and is very eye catching. Most of the crystals have some chipping and damage, however this is pretty typical due to the delicate nature of this mineral. The botryoidal mimetite cluster can be identified by the shift of colors from orange on one side of the specimen, to yellow-orange on the other, where the mimetite is located.

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.

About Mimetite

Mimetite is a rare lead arsenate chloride mineral, often found in shades ranging from bright yellow to orange, brown, and occasionally green. Its crystals form in a hexagonal structure, typically appearing as prismatic or rounded barrel shapes, though they can also form in botryoidal or globular clusters. This mineral belongs to the apatite group and is closely related to pyromorphite and vanadinite, with which it can sometimes be found in mixed forms. Mimetite's vibrant colors and crystal formations make it a popular specimen among mineral collectors, as it is often highly aesthetic and eye-catching.

This mineral is usually found in the oxidized zones of lead ore deposits, commonly associated with minerals such as galena, wulfenite, and cerussite. It can be found in notable deposits worldwide, including locations in Mexico, Namibia, and Australia, where large and well-formed specimens have been unearthed. Mimetite crystals are relatively fragile due to their lead and arsenic content, requiring careful handling. Despite its appeal, mimetite is not used in jewelry or as a decorative stone because of its toxic elements, making it mainly a collector's mineral.
