A very WEIRD specimen with sharp dendrites of native copper erupting from and going back into a very strangely-colored smithsonite which has yellowish color and waxy luster to it (the first picture is more accurate for color). I've never seen the like, and neither had the Sussmans. This specimen comes from the Heini Soltau collection, and was purchased directly from him in Africa. 8 x 6.5 x 4 cm
