BIXBYITE SPECIMENS

Bixbyite is a rare, lustrous, metallic, dark black, iron manganese oxide mineral. It's often found in hydrothermal veins and cavities, metamorphic rocks, and lithophysal (felsic volcanic rock) cavities in rhyolite. It can be found naturally associated with beryl, quartz, spessartine garnet, hematite, pseudobrookite, hausmannite, braunite, and topaz. The bixbyite and topaz combination is considered one of the more desirable associations.
