Physical properties

Formation & geological history

Synthetic creation manufactured by melting silica and other minerals in a furnace to simulate the opalescence of natural stone. It is essentially an industrial glass product.

Uses & applications

Primarily used for holistic healing practices, decorative carvings, jewelry beads, and as an affordable alternative to natural opal and moonstone.

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.
