Opalite is a synthetic substance designed to resemble natural opal. Usually made from glass and resin, it may contain additional metals to improve its hue and opalescent qualities. Commonly utilized as a cost-effective substitute for genuine opal in jewelry and decorative pieces, opalite lacks the distinct play-of-color found in precious opal. Nevertheless, it can display a variety of shades such as white, blue, green, and purple, often showcasing an iridescent or milky look.
