Formation & geological history
Man-made via a process of melting silica and other additives to create a simulated opal effect. Unlike natural volcanic or sedimentary rocks, this is a synthetic product designed for aesthetics.
Uses & applications
Used extensively in jewelry, ornamental carvings, decorative sculptures, and the metaphysical/holistic healing community.
Geological facts
While frequently sold alongside natural crystals, Opalite is a type of glass. It is known for its 'Schiller effect' where it appears blue against dark backgrounds and orange/gold when light passes through it.
Field identification & locations
Identify by its perfect uniformity, absence of natural inclusions, and the distinct orange glow when held up to a light source. Commonly sold at gem shows and metaphysical shops.
