This interesting thumbnail specimen consists of 5 or 6 Bixbyite cubes that are partly embedded in a topaz crystal. The cubes do not exceed 0.1" (3 mm) but are in excellent condition and have excellent form. All have the standard gray-black color and submetallic luster, though most are dulled somewhat by tiny crusts of rhyolite. The topaz crystal is also in good condition and has moderately good form due to heavy rhyolite inclusions. It has a pale brown color but is only transparent at its termination, due to the aforementioned rhyolite. The piece is affixed to an octagonal acrylic base with an adhesive putty.
