Thomas Range, Juab County, Utah, USA
52mm x 31mm x 33mm
A super sharp bixbyite crystal and several topaz crystals are well exposed on the side of this rhyolite matrix. The bixbyite crystal is pitch-black and shows sharp indentations caused by modifying faces. It does have one corner missing but otherwise is amazing! As well, there are a couple of doubly-terminated topaz crystals on the same face as the bixbyite. Classic Thomas Range!
