Hambergite is a mineral that belongs to the borate mineral family, which is primarily found in boron-rich environments. It contains boron, oxygen, and calcium as its main chemical components and has an orthorhombic crystal system. Alternative terms used for hambergite include calcium borate or calcium pentaborate hydrate, but these terms are not commonly used. It is sometimes associated with other minerals such as colemanite, ulexite, and boracite, which are all borate minerals as well. Some collectors and hobbyists may refer to this mineral simply as "hamberg," but this term may not be widely recognized within scientific or mineralogical communities.
