Pyromorphite For Sale

Pyromorphite is a mineral species composed of lead chlorophosphate. It forms small, hexagonal crystals ranging from glowing green to yellow, orange, and red-brown. These minerals pop from whatever their association may be in a spray of vibrant, flatly terminated crystal clusters. Pyromorphite is found almost everywhere, but the most eye-catching specimens come from China, Australia, and along the Rocky Mountains in the United States.

What Is Pyromorphite?

Pyromorphite is the mineral lead chlorophosphate (Pb5(PO4)3Cl), a member of the hexagonal mineral apatite group. This mineral forms small, hexagonal, prismatic crystals that are often terminated horizontally. The lead in this mineral is responsible for the range in color from vibrant greens to oranges, yellows, and red-browns. In the past, this mineral was used as an ore of lead if the amount was significant enough for extraction. The structure and formula is extremely similar to that of the mineral mimetite, except that mimetite contains arsenate instead of phosphate. This difference becomes apparent in natural pyromorphite formations where portions of the mineral are partially replaced by mimetite.

Where Is Pyromorphite Found?

Pyromorphite is found in lead deposits across the globe. Interestingly, locality has been known to inform color, shape, and size. While specimens from Germany exhibit squat, barrel-shaped crystals in a classic brownish color, specimens from China form in larger barrel-shaped crystals that flash an alien apple-green color. These Chinese specimens are some of the most sought after of all the pyromorphite on the market. The U.S. currently produces some of the most astonishing globular masses of crystals that range from green to orange and all blends in-between.

How Is Pyromorphite Formed?

In oxidation zones of lead ore deposits, pyromorphite will form as a secondary mineral when phosphate is introduced to the deposit. Crystals form as waters seep in and chemically alter the lead that has been exposed to heavy winds and abrasion.

Is Pyromorphite Toxic?

The lead in pyromorphite can be harmful if absorbed into the bloodstream by inhalation or ingestion. The crystals won't pose a health hazard just sitting on a shelf, but we recommend washing your hands after handling.

Common Associations

Pyromorphite often forms associations with other lead-based minerals, including wulfenite, galena, vanadinite, and cerussite. Its most common association is with mimetite, which often replaces pyromorphite. Both minerals are easily confused for one another, but aside from mimetite’s yellow color and occasionally hollow crystals, in-depth analysis is usually needed to determine which species is which.
