Several products of the oxidation of stibnite and jamesonite have been found as earthy aggregates.
Crystals filled by fine jamesonite needles have also been found.

Between and scattered upon the large crystals of these species are small needles of rutile, little gray rhombs of calcite, monazite and apatite microcrystals, and (oddly) tiny hairs of metallic black jamesonite
