6T87BS4: Good specimen of this rare vanadate of lead and bismuth, from its type locality. (Pottsite has only been found at three localities in the world, two of them in Nevada). It is associated with another rare bismuth vanadate, Clinobisvanite, relatively easy to distinguish from Pottsite due to its reddish color and its fluorescence under shortwave ultraviolet light.
