I can count at least 9 complete Topaz crystals on this specimen. All are in excellent condition, with no human-induced damage, and have generally good form, though a few are somewhat warped and have incomplete terminations. Almost all of them have an orthorombic prismatic form and are topped with pseudohexagonal pyramidal terminations that are truncated with small basal faces. Their color ranges from a pale gold with a hint of pink to a deeper, almost rusty orange. All have a vitreous luster and are transparent, though the deeper-colored crystals tend to be slightly cloudy, whereas the paler crystals are quite clear. They also have minor internal flaws and/or veil-like inclusions. The host rock on which they rest is cream-colored, and seems to be partially composed of similarly-colored, broken Topaz crystals. There are also probably many tiny crystals growing on its surface, as it sparkles lightly. It is affixed to the inside of a plastic domed thimble box for display.
