Physical properties
Hardness of 6.5 to 7 on the Mohs scale, translucent blue-gray color, waxy to vitreous luster, and a microcrystalline trigonal structure with botryoidal surface formations.
Formation & geological history
Formed by the precipitation of silica-rich fluids in volcanic rock cavities at low temperatures.
Uses & applications
Popular among mineral collectors and used for ornamental cabochons in jewelry.
Geological facts
The unique botryoidal texture creates optical reflections resembling water droplets or soap bubbles.
Field identification & locations
