Physical properties
Hardness: 6.5-7 on Mohs scale; Color: Black and white or dark brown and tan stripes; Luster: Vitreous to waxy; Structure: Microcrystalline quartz; Cleavage: None; Specific Gravity: 2.6-2.65
Formation & geological history
Formed from sedimentary processes where layers of clay or mineral-rich silt solidified over millions of years, often associated with ancient seafloors or riverbeds.
Uses & applications
Primarily used for decorative purposes, jewelry (beads, cabochons), carvings, and as a popular stone for tumble polishing and metaphysical collecting.
Geological facts
Despite its name, it is technically a form of chalcedony rather than a true jasper in some classifications; it is often called the 'stone of balance' due to its contrasting colors.
Field identification & locations
Identify by its distinctive high-contrast banding resembling zebra stripes. Commonly found in India, Russia, and Africa. It is a very durable stone suitable for daily-wear jewelry.
