Opalite is a type of synthetic glass often mistaken for a gemstone due to its alluring translucence and the play of colors similar to those seen in opals. Unlike natural gemstones, opalite is man-made, primarily from dolomite and metal to create its distinctive shimmering and milky appearance. It typically exhibits a soft, opalescent sheen with a blue or orange glow when light passes through it, making it popular in jewelry and decorative objects.(geologyscience.com)
