Opalite is known as a trade name used for several different types of synthetic or treated stones that are meant to resemble natural opal.
The term “opalite”was first used in the late 19th century to describe these types of opal imitations. It is a soft and subtle dynamic iridescent man-made glass resin composed primarily of the mineral dolomite fused with metal to produce an opalescent appearance.
Opalite in its natural form is a stone that comes from opalised volcanic ash which rarely happens. It can usually be found in Africa and Brazil.
Opalite is an artificial or man-made material, so it does not occur naturally. It is produced by various methods, including heating or irradiating natural stones like chalcedony, glass, or synthetic resin materials.
Opalite is primarily used as a gemstone and ornamental material. It is used to create jewelry, decorative objects, and various craft items. It is popular due to its resemblance to natural opal, but has a lower cost.
Opalite may display an opalescent play of color, similar to natural opal. However, the patterns and colors are usually less complex and varied than in natural opal. Opalite is often translucent to opaque, with a vitreous or waxy luster. Its hardness is typically in the 5-7 range on the Mohs scale.
Opalite has a relatively low global value compared to natural gemstones. It is mass-produced and widely available and so it is generally inexpensive.
The prices for opalite jewelry or specimens defers depending on the size, quality, and any additional treatments.
Opalite does not have the rarity or collector value of natural opal, so its global market presence and financial worth are relatively modest. It is primarily used as an affordable opal substitute or decorative material.
