Physical properties

Formation & geological history

Formed through the deposition of silica from hydrothermal solutions or in sedimentary environments. Its red color is derived from high iron/hematite content during the mineral's formation in volcanic or metamorphic processes.

Uses & applications

Used primarily as a gemstone for jewelry (cabochons, beads), decorative carvings, and as a landscaping stone. It is also a popular lapidary material for rock tumbling.

Geological facts

Red Jasper has been used since ancient times for amulets and seals. It was referred to as the 'warrior stone' in various cultures, believed to provide physical strength and protection.

Field identification & locations

Identify in the field by its deep red color, opaque transparency (light does not pass through), and smooth, waxy feel when water-worn. Commonly found in riverbeds, gravel pits, and desert regions globally, especially in India, Brazil, and the USA.
