Formation & geological history

Man-made via a process of melting silica together with metals and minerals to imitate the play-of-color in natural opal. It is not found in nature; it is a purely synthetic material produced in laboratories.

Uses & applications

Primarily used for decorative purposes, jewelry (pendants, rings, spheres), and in the metaphysical community for crystal healing and meditation tools.

Geological facts

Opalite is often mistaken for moonstone or opal by beginners. It is specifically designed to exhibit a milky blue glow when viewed against a dark background and a warm amber hue when light passes through it.

Field identification & locations

Identify by the lack of natural inclusions and the presence of tiny gas bubbles when viewed under magnification. It is perfectly uniform in a way natural stone rarely is. Collectors should note it is distinct from high-value 'natural opal'.
