This is particularly exceptional for a Chinese azurite-- the best way to describe it is probably this: if mineral specimens could reproduce, this would be the product of crossing a Liufengshan piece with one from Milpillas. The luster is almost wet, and the crystal size is substantially larger than that seen in the usual "blue geodes" lined with small azurites (for example, see specimen CNAZ28). The display face is also damage free, a result of its very slight convex shape.   

It really is a good piece, I'd say better in person than in the photographs.   Even Dr. Liu's "Fine Minerals of China" book doesn't have one this good (in my opinion), and compared to the old, ball-like Shilu clusters, I think this comes out quite far ahead, not necessarliy on shape but certainly on luster and depth of color.  I don't typically emphasize things like this so much, but again, this is really really good for China, and it would be quite hard (I think) to come across a better one.
