A 2cm Uraninite crystal perched nicely on the top of this specimen. The crystal is dull and imperfect perhaps as a result of chipping away the surrounding matrix to expose the crystal. The matrix is a pinkish yellow color with swirls of deep purple Fluorite.
Ex. Wiliam Pinch with label.

A choice specimen of black Uraninite crystal group. The original label said it was Euxenite and from Mitchell, North Carolina. It is metamict and tested out to contain U & Pb by EDS. I believe it is Urananite and from the Swamp quarry.

This is an oldie from the David London collection. In the photos are seen black Uraninite crystal grains with dark green Dickinsonite and pinkish Natrophilite with Microcline. It was originally a specimen that belong to George J Brush. Brush was a famous mineralogist during the mid 1800's and served as the editor of the American Journal of Science and a professor at Yale University. His label is shown in the provenance tab.
