Incredibly old crystals formed only a billion years after the big bang! Estimated by petrologists to be approximately 3,400 million years old, these perfectly formed pinkish zircon crystals have remained unchanged with time. Only a few millimeters long, these doubly terminated crystals exhibit scientifically perfect angled facets and because the mineral zircon in one of hardest gemstones, there are no scratches on the facet faces. They are shinny and clear.
Formed in the uplifted metaphoric rock which composes much of the Beartooth Mountains of Wyoming and Montana, these tiny crystals were weathered from host rock and washed into drainage streams. One creek head watered in the range is Ruby Creek, it is located just north and west of Clark, Wyoming. During normal panning for gold and heavy minerals these beautiful crystals can be collected and, because zircon is a high density mineral, the crystals pan out easily with any gold and other heavy minerals.
One technique used in gemstone identification is fluorescence. These crystals fluoresce yellow when exposed to short wave ultraviolet (UV) light.
