Blue-and-white opalite sphere

Opalite (commercial synthetic or glass-based imitation; not true opal), typically silica glass or synthetic opalescent material

AI-generated identification · may be incorrect

Translucent milky white with blue opalescence, vitreous luster, and no visible crystals or cleavage; hardness commonly about 5–6 Mohs if glass. The perfectly spherical polished shape indicates lapidary processing; composition cannot be confirmed visually.

Physical properties

Formation & geological history

Usually manufactured by melting and opacifying glass, then cutting and polishing it; therefore it has no natural geological age or formation environment. Natural common opal is hydrated amorphous silica (SiO₂·nH₂O), but this appearance is commonly sold as imitation opalite.

Uses & applications

Used for inexpensive spheres, beads, carvings, spiritual décor, and costume jewelry. It has modest collector value compared with genuine precious opal.

Geological facts

Opalite’s blue glow is an optical effect from internal scattering and surface reflections, often strongest against a dark background. It is frequently mislabeled as “moonstone” or “sea opal.”

Field identification & locations

Check for perfectly uniform color, glassy bubbles, and lack of natural matrix; these favor synthetic opalite. Genuine opal is also amorphous but commonly shows play-of-color, irregular patterns, or natural host rock.
