2" Wulfenite & Green Botryoidal Mimetite Association - Mexico

This specimen contains pristine orange wulfenite crystals that formed in association with green, botryoidal mimetite, collected from the Qjuela Mine in Mapimi, Mexico.

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.

About Wulfenite

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.

Safety: 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 The Ojuela Mine

Ojuela is not one mine but a complex of multiple mines in the same general area, located just northwest of Mapimi, Mexico. It was established in 1598 after the discovery of an old abandoned silver and gold mine. As mineral production increased and the mineral potential was confirmed, the town (Ojuela settlement) adjacent to the mine, along with the city of Mapimi, began to grow as well. The mining settlement was such a success that it contained a post office, warehouses, stores, saloons, a church, and housing for the miners. Once minerals were collected, they were processed in Mapimi, which also played a role in the rapid development of the city. Around the start of the 20th century, most of the mineral deposits were exhausted, resulting in the abandonment of the mines and settlement.

The mine is well known by mineral collectors for its aresenate minerals and a variety of other mineral species: approximately 117 have been identified from the area. Some of the most popular minerals include adamite, austinite, hemimorphite, scorodite, platternite, aurichalcite, rosasite, calcite, wulfenite, mimetite, iridescent goethite, and fluorite.
