Durbachite: The Rare Lead Phosphate Mineral with a Vitreous Luster

Durbachite is a rare mineral, with the chemical formula Pb5(PO4)3Cl. It was discovered in 1867 in the Durbach mine in the Black Forest of Germany, hence its name. It is a lead phosphate mineral that contains chlorine, and it crystallizes in the monoclinic crystal system. It is typically found in the oxidized portions of lead deposits, often associated with other lead minerals such as galenite and cerrusite.

Durbachite is a relatively soft mineral, with a Mohs hardness of around 3.5 to 4.5, and it has a vitreous luster. It is usually colorless or white, but it can also be found in yellowish or brownish shades. It has a high specific gravity of around 6.7, which means that it is relatively dense for a mineral of its size.

Durbachite is not a well-known mineral, and it is not commonly found in many mineral collections. However, it is an interesting mineral for collectors who specialize in rare and unusual minerals. It can be found in some mineral shops and online marketplaces, but it may be difficult to find in large quantities or in high-quality specimens.
