This comes from a recent discovery of a small-scale mining operation around Durango, Mexico. Some of the pieces I looked at still had roots on them, indicating a deposit relatively close to the surface. The opal itself is remarkably clear and intact. The fluorescence is extreme under both long wave and short wave (short wave pictured). 

This piece has crystallized on a brownish chalcedony matrix. It comes mounted on a black acrylic base. It's in great shape, without any dings.
