Hyalite Opal | Mexico | UV Reactive Collector Mineral Specimen

This authentic Hyalite Opal from Mexico is a rare variety of opal prized for its exceptional clarity and intense ultraviolet (UV) fluorescence. Under UV light, the specimen emits a vivid green glow due to trace uranium content — a hallmark feature of true hyalite opal.

In natural light, hyalite opal appears colorless to milky-clear with a subtle glassy luster, often forming botryoidal or crust-like growth on matrix. Unlike common opal varieties, hyalite is valued primarily for its optical properties and fluorescence rather than body color.

Mexican hyalite is especially sought after for its strong reaction under UV and clean formation, making it a favorite among advanced mineral collectors and fluorescent mineral enthusiasts.

This specimen is completely natural and unaltered.
