1.9" Descloizite on Wulfenite Crystals - Los Lamentos, Mexico

This specimen contains brown wulfenite crystals on a sparkling matrix. It was collected from the Los Lamentos Mountains of Chihuahua, Mexico and measures 1.9 x 1.65".

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 the fact that they are lead-based, washing your hands following handling is strongly suggested.

Descloizite has the chemical formula PbZn(VO4)(OH) and is often found as a secondary mineral in the oxidation zone of multi-metallic complex ore deposits.

The lead in the descloizite can be harmful if absorbed into the blood stream by inhalation or ingestion. The crystals won't pose a health hazard just sitting on a shelf but it would be recommended to wash your hands after handling.
