Yellow crystals of the extremely rare Th-U mineral althupite from the type and only known locality worldwide in Kobokobo (Kobokobo Pegmatite, Mwenga, South Kivu, DR Congo). Vandenbroucke Museum collection from Waregem, Belgium.

Althupite (IMA symbol: Ahp[1]) is a rare aluminium thorium uranyl phosphate mineral with complex formula written as AlTh(UO2)7(PO4)4O2(OH)5·15H2O, from a granitic pegmatite. It is named after its composition (ALuminium, THorium, Uranium, and Phosphorus).[2][3][4]
