Hambergite (Be2BO3OH) is a beryllium borate mineral named after Swedish explorer and mineralogist Axel Hamberg (1863–1933). The mineral occurs as white or colorless orthorhombic crystals.[3][4][2]

Tabular, terminated crystal from the Gem Hill, Mesa Grande District, San Diego County, California (size: 1.5 × .8 × .5 cm)

Occurrence

Hambergite occurs in beryllium bearing granite pegmatites as a rare accessory phase. It occurs associated with beryl, danburite, apatite, spodumene, zircon, fluorite, feldspar and quartz.[2]

It was first described by mineralogist and geographer W. C. Brøgger in 1890.[5] The type locality is Salbutangen, Helgeroa, Langesundsfjorden, Larvik, Vestfold, Norway where it was found in a pegmatite dike of nepheline syenite composition.[3][6]
