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.
