Physical properties
Hardness of 6.5-7 on the Mohs scale, vitreous to dull luster, opaque white to grey with complex brecciated patterns.
Formation & geological history
Formed through the silification of clay or volcanic ash in sedimentary environments, often millions of years old.
Uses & applications
Primarily used for cabochons, decorative carvings, and lapidary display collections.
Geological facts
Also known as white jasper or porcelainite, it features a smooth texture resembling unglazed porcelain when cut.
Field identification & locations
Identify by its porcelain-like fracture and microcrystalline hardness. Commonly found in arid regions and riverbeds worldwide.
