1" Lustrous Black Bixbyite Crystal on Matrix - Utah
This is an incredibly lustrous black bixbyite crystal, collected from the Thomas Range of Utah. A small topaz crystal can be found along one edge of the matrix. It has been mounted to an acrylic display base with mineral tack.
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.
It's named after Maynard Bixby, the American mineralogist who discovered it.
