Thomas Range, Juab County, Utah, U.S.A.
This small crystal is rather unusual due to its flattened orthorhombic prismatic form and its termination. It grew into a piece of the rhyolite host rock, disturbing its development, and causing the termination to split into two smaller terminations that rest alongside each other. Otherwise, it is in excellent condition and has very good form. Its pale brown color and vitreous luster are standard for the locality, and it is transparent and very clear where the rhyolite is not included. The piece is attached to a square acrylic base with an adhesive putty.
