A beautiful single crystal so sharp that it looks like it has been carved, with razor sharp edges and faces. The luster is so great, its like mirror finish as much as an azurite can. These crystals have the near-metallic, almost translucent surface sheen of blue for which this mine will someday be famous, caused by a thin secondary generation of azurite deposited over a velvety malachite pseudomorph underneath (the light shines through the thin blue, reflects off the underlaying malachite, and comes back out that shimmering blue you see hints of in these photos). MUCH MUCH BETTER In PERSON! Minor, very minor, edge wear on the back face and left side-rear-edge; otherwise pristine and complete 360 degrees around and very starkly geometric in form. For such a large crystal, this is half the price a comparable-looking piece from Tsumeb would run, in my opinion.
