This small thumbnail specimen consists of tiny (nearly microscopic) crystals of the mineral schrockingerite on matrix. Under a loupe, tiny crystal faces may be seen, but no details of the triclinic form can be distinguished. This specimen fluoresces a bright yellow-green under both short and long wave ultraviolet light-an indicator of uranium. This specimen shows no damage. Schrockingerite is named for the Austrian geologist J. von Schrockinger.
