Physical properties
Mohs hardness of 7, white to clear color, vitreous to sugary luster, hexagonal crystal system, specific gravity of 2.65.
Formation & geological history
Formed when silica-rich water precipitates within rock fractures or cavities, often in hydrothermal environments.
Uses & applications
Used in decorative items, jewelry making, and collected as mineral specimens.
Geological facts
Druzy forms as countless tiny crystals grow on a parent rock surface, creating a glittering texture.
Field identification & locations
Easily identified by its sparkling sugar-like crystal coating and resistance to scratching; found worldwide in geode cavities.
