One of the richest specimens remaining from a rare lone pocket that was harvested long after the rest of the material was turned into nukes. Highly collectible. Secondaries from Mi Vida tend to be quite rare and not so grand. The Uraninite has altered into bright yellow Uranopilite and Natrozippeite which react under UV lighting. Accented with Gypsum crystals. Very fair price for such historic material. The mine is a death trap and remediation with no more ore presently accessible.
