One fact I have to mention first: "This beautiful specimen is MUCH BETTER IN PERSON". Anyhow, I was unable to convey the fine clarity, richness of faces and great luster in the photos. The cuboctahedral crystals here are so clear that you can look through them and see the matrix. The luster is great as mentioned before and the overall aesthetics superb. Small imperfection at the periphery, the rest of the entire display face is pristine. A great piece.
