Opalite
Synthetic Opaline Glass · Decorative Stone / Simulant
Crystal System
Amorphous (Non-crystalline) glass structure; typically processed into rounded cabochons or tumbled stones.
Mineral Group
Artificial Glass (Man-made material)
Chemical Formula
Mainly SiO2 with additives (Na2O, CaO) and micro-dispersed particles
Formation Process
Industrial manufacturing: Molten silica glass is combined with metal ions or fluorescent compounds to create the opalescent effect.
About This Crystal
A semi-translucent to milk-white material with a distinct bluish glow when light is reflected, and a golden/orange hue when light is transmitted. It features a vitreous (glassy) luster and a smooth, uniform surface.
Physical Characteristics
Color: Bluish-white to clear; Streak: White; Cleavage: None; Fracture: Conchoidal (shell-like); Specific Gravity: ~2.4 - 2.5; Fluorescence: Often exhibits a faint greenish or yellowish glow under UV light.
Optical Properties
Singly refractive (isotropic); exhibits a distinctive opalescence due to the Tyndall effect; refractive index typically ranges between 1.47 and 1.51.
Hardness & Durability
Origin Region
Produced in factories globally, primarily in China and India; not a natural geological find.
Hardness & Durability
Mohs hardness: 5.5 to 6. Brittle toughness; moderate stability but can be scratched by quartz or steel. Susceptible to rapid temperature changes.
Care & Maintenance
Clean with warm soapy water and a soft cloth; avoid ultrasonic cleaners and harsh chemicals. Store separately from harder stones to prevent surface scratching.
Rarity & Value
Common; very inexpensive. Often sold as a bulk tumbled stone or mass-produced jewelry components. Not rare as it is produced industrially.
Special Characteristics
Tyndall Effect: Light scattering makes the stone appear blue against a dark background and orange when light passes through it (allochroism).
Lore & History
In modern crystal healing, it is often associated with the Crown and Third Eye chakras, used for transitions and overcoming fatigue. Historically, it is a 20th-century creation marketed as a less expensive alternative to natural Moonstone or Opal.
