OPAL9

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 is a neat miniature, where the opal seems to have "percolated," up on the chalcedony matrix. Mounted on black acrylic base. Pictures show both sides.

Without damage.
