Physical properties

Hardness: 6.5-7 on Mohs scale; Color: Red to brownish-red; Luster: Vitreous to dull; Crystal structure: Trigonal/Microcrystalline; Cleavage: None; Specific Gravity: 2.58-2.91

Formation & geological history

Formed via the deposition of silica from hydrothermal solutions or in sedimentary environments. Its red color is derived from high iron content incorporated during formation.

Uses & applications

Widely used for ornamental carvings, jewelry (cabochons and beads), and as a healing stone in metaphysical communities.

Geological facts

Jasper is an opaque variety of chalcedony. The name originates from the Greek word 'iaspis', meaning 'spotted stone'. It is known as the 'Supreme Nurturer' in folklore.

Field identification & locations

Identifiable by its deep red color, opacity, and smooth, waxy feel when tumbled. Unlike carnelian, it is typically opaque even when held to light. Found globally with major deposits in India, Brazil, and the USA.
