Physical properties
Hardness: 5.5-6 (Mohs scale); Color: cobalt blue with internal metallic foil/glitter; Luster: Vitreous; Structure: Amorphous; Cleavage: none (conchoidal fracture).
Formation & geological history
Formed through a synthetic melting process where copper or other metallic elements are crystallized in a cooling melt of glass; modern geological age (anthropogenic).
Uses & applications
Primarily used in jewelry making, fashion accessories, and decorative beadwork due to its aesthetic appeal and low cost compared to natural gemstones.
Geological facts
Also known as Blue Goldstone, this material was originally discovered by accident in 17th-century Venice by monks or alchemists attempting to make gold.
Field identification & locations
Identify by looking for uniform glittery internal reflections (aventurescence) and smooth, rounded surfaces without natural crystalline growth patterns; found in craft and jewelry markets globally.
