Item Description

These are some of the most well-known specimens from the western United States. Bixbyite is at its best when it comes from Utah with the classic large, black crystals that show beautiful modified / comples crystallization. This piece hosts a very sharp, highly lustrous, jet black colored cubic crystal of Bixbyite with classic trapzeohedral modifications on the corners sitting on rhyolite matrix with associated sherry colored Topaz crystals. The Bixbyite has a partially interrupted growth where it essentially grew around the surrounding white rhyolite to create an interesting effect. No real damage that I can see with the naked eye. From the worldwide thumbnail / miniature collection of Irv Brown. Valued at $450.
