A fine combination specimen from the Tsumeb Mine. The very vuggy, sculptural matrix is richly covered with two varieties of willemite: larger, translucent, "wet-look," sea-green botryoids; and smaller, grayish-green, lustrous botryoids. The willemite is fabulously accented with swirling bands of powder-blue plancheite, a rare secondary copper silicate. Outstanding and seldom seen combination material from this renowned locale. Ex. Rob Smith Collection.
