Rosenbuschite was first described by W. C. Brøgger ( 1887 and 1890) from a nepheline syenite pegmatite on the tiny island Skudesundskjær in Langesundfjord in Southern Norway. Langesundfjord remained the only locality for rosenbuschite until it was reported by A. E. Törnebohm (1906) as an accessory mineral in the nepheline syenite at Norra Kärr in Sweden, and it has later been found also in a few other places, always in nepheline syenitic rocks.
