Exceptional cube of the rare niobium-containing species Lueshite, with good metallic luster and typical back-silver color. What makes this so grand is the size and, most especially, the sharpness of the crystal. I am told that these came out only sporadically, and mostly 20-plus years ago. This is the largest I have had for sale out of several over the years. It is a significant example for the species.
