Much shattuckite has come out, and often you can get beautiful drusy carpets of the crystals, which look like blue velvet, on thin plates. Sometimes you get nice pockets, but not always of this top quality. This is TOP quality for condition, color intensity, and a rolling 3-dimensional surface inside. It screams out in color, and is one of the best such pockets I have seen in the few years of trickling production out of here. There are really few colors in nature so intense. This vug is nearly 2 inches across, and the crystals within are pristine and protected. Again, if you think you have seen TOP color for this material, I can only say that this piece is another 10% beyond, in color, anything I have seen for sale on a general basis.
