“Specimen is 4.1 x 2 x 3.2 cm A gift to Howard Zeller from, and presumably found by Bill Sharp. From Dr Zeller's personal collection. I am assuming this is the original label. It was from a box of miscellaneous radioactive minerals all from Dr Zeller's collection, which was bought at the Colorado School of Mines. The color of the actual mineral is a little more yellow, and I tried editing the photo to get it as close as I could.”
