Hyalite Opal - San Luis Potosi, Mexico

Macro photos of glassy botryoidal hyalite on matrix. The textures are remarkable in white light, and LW produces a very bright green fluorescence. SW, not pictured, yields the same color. The field of view shown is 20-25mm.

Lit by a 365nm flashlight. Specimen is 70 x 64 x 56mm.
