This thumbnail specimen consists of a single Zircon crystal that is not quite complete but is in excellent condition. Its doubly-terminated tetragonal prismatic form is a bit rough but still quite good, and it has the red-brown color that is common for its species. The crystal is dimly translucent due to intense internal fracturing and has a slightly dull adamantine luster. When bathed in longwave ultraviolet light, it glows a noticeable yellow.
