Bromellite occurs in hydrothermal calcite veins and veinlets in skarn (Mindat).

At Langesundsfjord, Norway, bromellite occurs in vugs in natrolite, hydrothermally altered from nepheline, in syenite pegmatite associated with natrolite, diaspore and chamosite (HOM).

Near Ekaterinburg in the Ural Mountains, Russia, bromellite has been found in an emerald mine associated with phenakite (Dana).

At the type locality, Långban Sweden, bromellite occurs in hydrothermal calcite veins in a calcite-hematite skarn associated with swedenborgite, richterite and manganophyllite (Dana, Mindat, HOM)

Bromellite has been reported in skarn south of Sierra Blanca, Hudspeth County, Texas, USA (Dana).
