Simply stated, this is a superior specimen! An elegant, curving cluster of cavansite balls, displaying the deepest royal blue color and almost iridescent luster, has grown across drusy, tan stilbite crystals. The largest ball of cavansite is over 2 cm across. In addition, the base of the specimen has a group of lustrous, doubly terminated stilbite crystals, to 1.5 cm. The color contrast of minerals and the 7 cm long, linear cluster of cavansite, easily make this specimen very desirable and FAR above the crowd.
