Physical properties
Hardness: 5.5-6 (Mohs scale); Color: Deep indigo blue with glittery reflecting inclusions; Luster: Vitreous (glassy); Crystal Structure: Amorphous (non-crystalline glass); Specific Gravity: ~2.5
Formation & geological history
Created in a low-oxygen reducing atmosphere; blue versions use cobalt or manganese combined with copper/silica. Originally popularized in 17th-century Venice (Murano glass).
Uses & applications
Primarily used in jewelry (rings, pendants), beads, figurines, and healing crystal collections.
Geological facts
Despite its name, it is a synthetic glass and not a natural stone. The 'gold' name comes from the glittery effect produced by metallic inclusions through a process called aventurescence.
Field identification & locations
Identify byIts intense, uniform 'galaxy' glitter effect and lack of natural mineral inclusions. It is found in stores worldwide rather than geological field sites.
