Several Topaz crystals constitute this specimen. Most are in excellent condion, though a few are obviously broken. Those that are intact have excellent orthorombic prismatic form and are topped by steep pseudohexagonal pyramidal terminations that are truncated by small basal faces. These unbroken crystals have a pale golden coloration with a hint of pink, a vitreous luster, and are transparent with excellent clarity. Their internal perfection is spoiled, though, by internal fractures, veil-like inclusions, and other flaws. The largest of these crystals measures 1.0 x 0.4 x 0.3" (2.5 x 1.0 x 0.8 cm); the other crystals are considerably smaller than that. The host rock on which they rest is made up mostly of large, broken Topaz crystals that have a cream color and vitreous luster, but are opaque. I tried to put this specimen into a thimble box, but that one crystal was simply too large for it to fit.
