Rare Gemstone Mineral Abderite - Lead, Iron, and Phosphorus Crystals

Abderite is a rare mineral species that belongs to the class of phosphate minerals. It is composed of lead, iron, and phosphorus, with the chemical formula PbFe3(PO4)3. It was first discovered in 1832 in the town of Abdera, in Thrace, Greece, hence its name.

Abderite crystallizes in the monoclinic system and typically forms tabular or prismatic crystals with a vitreous luster. It is usually found in oxidized lead-zinc deposits, often associated with other minerals such as galena, sphalerite, and pyromorphite.

Abderite is considered a rare mineral, and its occurrence is limited to a few localities around the world, including the type locality of Abdera, Greece, as well as in the United States, Australia, and South Africa. It is highly sought after by collectors due to its rarity and distinctive crystal formations, and it is often used as a gemstone.
