Impressive combination piece featuring Tennantite, Wulfenite, Malachite, and Quartz. The sharp Tennantites have an extensive oxide coating, and they range up to 4 cm on edge. There are numerous Wulfenites on the Tennantites. The butterscotch Wulfies have good luster and classic modified pillow habit. They range up to about .8 mm on edge. A number of them are sprinkled with micro spheres of vivid green Malachite, which is actually quite showy on that small scale. Overall, this is an excellent, fascinating combination piece from Tsumeb, in a rare larger size.
