Superb crystal pair of the rare manganese oxide Bixbyite, in Rhyolite matrix, from the well-known Wah Wah Mountains of Utah. The mirror-like cubes of Bixbyite have complex, and super-attractive, edge modifications, with the largest crystal being a significant 8 mm in size. Associated with these is a large amount of highly fluorescent Hyalite Opal. A very aesthetic, high-quality miniature.
