Physical properties

Formation & geological history

Man-made via a specialized glass-making process that involves creating spheres of silica to mimic the play of light in natural opal. Though it is synthetic, it is chemically similar to volcanic glass like obsidian but with added optical effects.

Uses & applications

Used extensively in fashion jewelry, beadwork, sculpture, and as a pocket stone for spiritual/holistic practices.

Geological facts

Opalite is often mistaken for natural opal or moonstone, but it is actually a human-made glass. Despite its synthetic origin, it is highly popular in 'healing crystal' communities where it is known as the 'Stone of Eternity.'

Field identification & locations

Identify by its perfect clarity, consistent glow, and the way it turns blue against a dark background and orange/honey-colored against a light background. Commonly sold at gem shows and metaphysical shops.
