This slab comes from largest piece of Ruggles material that I have been lucky enough to acquire. Upon taking the risk of cutting this, I was overjoyed to see that the orange Gummite is prominent over a large portion of the piece. There is some minor UV reactive Autunite that glows along with dark unconverted Uraninite. The dendritic orange Gummite is a classic for this location.
