Hambergite Minerals

Hambergite is a beryllium borate mineral with the chemical formula Be₂BO₃(OH,F), known for its rarity and gem-quality crystals. It typically forms in granitic pegmatites and hydrothermal veins, often associated with other beryllium minerals like beryl. Hambergite usually occurs as prismatic, colorless to pale yellow or grayish crystals, although it can also appear white or transparent. The mineral has a vitreous to greasy luster, and its transparency can range from translucent to nearly transparent in gem-quality specimens. It has a Mohs hardness of 7.5, making it relatively hard, and a specific gravity of about 2.35, which is notably low for a mineral of its hardness. Hambergite exhibits a perfect cleavage in one direction and is brittle, breaking with a conchoidal fracture. This mineral is named after Swedish mineralogist Axel Hamberg, and its crystals are highly prized by collectors for their rarity and brilliance.
