Physical properties
Mohs hardness 7; translucent blue body with vitreous luster, conchoidal fracture, and no true cleavage. The strong iridescent/gold surface sheen suggests a metallic coating rather than natural coloration; crystal form appears distorted or rough-terminated.
Formation & geological history
Quartz forms in hydrothermal veins and cavities, commonly from Paleozoic to younger geological settings. Aqua-aura specimens are natural quartz crystals treated in a vacuum with vaporized metals, commonly titanium, producing the blue-iridescent coating.
Uses & applications
Used mainly as a mineral specimen, ornament, or metaphysical collectible; untreated quartz is important in glass, ceramics, electronics, and abrasives. This piece has limited jewelry value unless well-faceted and durable.
Geological facts
Quartz is among Earth’s most abundant minerals and has a trigonal crystal structure. Coatings can wear or flake and may create colors not present in the original crystal.
Field identification & locations
Identify quartz by its glassy luster, hardness, lack of cleavage, and inability to scratch with a steel knife; blue aqua-aura coatings are uneven and strongly reflective. Common sources include Brazil, Arkansas, Madagascar, and China.
