Geological Facts

Opalite is often mistaken for moonstone or opal by beginners. It is distinctive because it turns blue against dark backgrounds but glows with an orange or amber hue when light shines through it.

Field Identification & Locations

Identify by the presence of tiny air bubbles under magnification and its characteristic orange 'sunset' glow when held to a light source. It is never found in nature and is strictly a manufactured material.
