Let me start off by saying that this is a truly fabulous combination piece consisting of excellent examples of both species. The gemmy Cerussites all have excellent clarity and luster, and the largest is 3 cm in size and sharply twinned! The drusy Duftite matrix has excellent color and superb luster, as well. The large crystal is pristine save for one tiny ding in a crevasse on a back face. The large Cerussite twin is freestanding and complete all around, otherwise. The one contacted Cerussite (shown in the upper-right photo on the far right side of the piece) suffers very little for it and is trivial anyhow, as you can see in the other three display angles. A terrific specimen Purchased from the Zweibels in 1978.
