Physical properties
Opaque reddish-brown, polished spherical beads with subtle coppery sparkle; glassy luster and no natural crystal structure. Hardness is about 5.5–6.5 Mohs; composition and specific gravity vary by recipe.
Formation & geological history
Manufactured by heating silica-based glass with copper particles and cooling it under controlled conditions; it has no geological age or natural formation environment.
Uses & applications
Used in jewelry, beads, ornaments, and decorative objects.
Geological facts
Despite its name and glitter, goldstone is not gold-bearing rock or a naturally occurring gemstone; its sparkling effect comes from metallic copper crystals in glass.
Field identification & locations
The uniform bead shapes, drilled holes, and consistent color identify this as processed material. It is often sold as red goldstone or aventurine glass.
