Rare Mineral Rammelsbergite: Discovery, Properties, and Uses
Rammelsbergite is a rare mineral, with the chemical formula Pb2(Fe2+,Fe3+)2(PO4)2(OH)2. It was discovered in 1869 in the Rammelsberg mine, near Goslar, Germany, and is named after this location. It is a member of the phosphate family of minerals and crystallizes in the monoclinic system.
Rammelsbergite is typically found in oxidized lead-bearing deposits, often associated with other minerals such as galena, sphalerite, and pyromorphite. It is a soft, brittle mineral with a Mohs hardness of around 2.5, and can be easily scratched or crushed. It has a white to pale yellow color, with a vitreous luster.
Rammelsbergite is not well known for its use in jewelry, as it is relatively soft and not very durable. However, it is sometimes used as a collector's item, particularly by mineral collectors who are interested in rare and unusual minerals.
