Hyalite Opal - Namibia

Hyalite opal from the Erongo Mountains in Namibia. In daylight these translucent, pale pieces appear subtle and glassy, but under UV light they glow with an intense green fluorescence — a signature property that makes hyalite opal so fascinating to collectors and cutters.

This material is ideal for experimenting with unique cabochons, carving projects, or simply adding to a reference collection.

Known for its strong UV response, Erongo hyalite is among the more distinctive opals found worldwide
