Physical properties
Hardness: 5-5.5 (Mohs scale), Color: Translucent to milky blue/amber, Luster: Vitreous to pearly, Crystal structure: Amorphous (non-crystalline), Specific gravity: 2.4-2.5
Formation & geological history
Produced by humans in industrial glass-making facilities. It is created by melting silica together with small amounts of metals (like copper or magnesium) to create a scattering effect similar to the Tyndall effect.
Uses & applications
Primarily used in decorative jewelry, beads, figurines, and as a pocket stone for metaphysical collecting.
Geological facts
Opalite is often mistaken for natural moonstone or opal. It exhibits an amber/orange glow when light passes through it (transmission) and a bluish glow when light reflects off it (scattering).
Field identification & locations
Identify by its uniform clarity, occasional internal swirl marks from glass cooling, and lack of natural inclusions. It is found in gift shops and gem trade markets worldwide.
