Physical properties

Formation & geological history

Opalite is a man-made variety of glass. While some 'natural opalite' exists as a form of common opal, the trade name usually refers to synthetic opalescent glass created by melting sand (silica) and adding trace metals or minerals to create the 'Tyndall effect' glow.

Uses & applications

Primarily used in the jewelry industry for beads, pendants, and carvings. It is also popular in holistic healing, meditation practices, and as a decorative collector's item due to its visual appeal.

Geological facts

Opalite is often mistaken for moonstone or genuine opal, but it is distinguishable by its uniform color and lack of internal 'fire.' It exhibits an 'inner glow' that appears blue against dark backgrounds and honey-orange when light shines through it.

Field identification & locations

Identify by looking for small bubbles (common in glass) and a very consistent, smooth texture without natural imperfections. It is not found in nature; it is manufactured in factories. It is commonly sold in metaphysical shops and bead markets.
