Physical properties

Mohs hardness 5-5.5, translucent to transparent, pearly to vitreous luster, amorphous structure, conchoidal fracture. Exhibits a milky white to pale blue color with a luminous or opalescent glow.

Formation & geological history

Man-made synthetic glass, intentionally manufactured to resemble opal or moonstone. Does not form naturally in geological environments.

Uses & applications

Primarily used in inexpensive jewelry, decorative items, and metaphysical crystal healing practices.

Geological facts

Often misidentified or misleadingly sold as 'moonstone', 'sea opal', or 'opal'. Its characteristic blue glow is due to the Tyndall effect from microscopic particles suspended in the glass.

Field identification & locations

Identified by its uniform, flawless appearance, presence of tiny gas bubbles (sometimes visible under magnification), and lack of natural crystalline structure or true play-of-color seen in precious opal.
