Polished & Natural Hyalite Opal Cluster – UV Reactive – Zacatecas, Mexico – 1.8 oz

This remarkable Hyalite Opal cluster from Zacatecas, Mexico weighs approximately 1.8 oz and measures 1 in x 1.25 in x 1.5 in, featuring a beautiful combination of natural and polished surfaces that highlight the specimen's exceptional clarity and fluorescence.

The specimen displays the glassy, water-clear appearance that makes Hyalite Opal one of the most distinctive varieties of opal. Under normal lighting, the material exhibits a smooth, transparent to translucent luster, while exposure to 365nm UV light reveals its famous bright green fluorescence, creating a dramatic transformation that collectors highly prize.

The combination of natural formation and polished surfaces allows both the raw geological character and the optical qualities of the Hyalite to be appreciated. Material from Zacatecas is especially sought after among fluorescent mineral collectors due to its strong UV response and attractive crystal formations.
