- Hyalite Opal
- Small Cabinet, 7.5 x 5.3 x 4.7 cm
- Electric Opal Claim, Zacatecas, Mexico
Three islands of green, fluorescent Hyalite Opal adorn the matrix on this piece from Zacatecas. The largest of the Opals is 2.1 cm, and, of course, it has terrific fluorescence. These fluoresce in the natural sunlight, just holding it outside!
