Cavansite is a recently discovered mineral. It was named after it's elements: Calcium, Vanadium, Silicate. The color of the Cavansite is what I look for when selecting this mineral. the color of this Cavansite is incredible. It's bright blue, sparkly and has wonderful little white Stilbite crystals that accent the "run," of Cavansite on the matrix. This will really add both color and aesthetics to your collection. On the back top of the Cavansite is a little contact spot (doesn't detract from the appearance).
