Physical properties

Hardness: 6.5-7.0 (Mohs); Color: Multicolored (green, red, cream, lilac); Luster: Vitreous to waxy; Texture: Fine-grained, opaque; Fracture: Conchoidal

Formation & geological history

Formed from the deposition of silica from water in sedimentary environments, often replacing organic materials or filling cavities. The distinct colors are caused by iron oxides and other mineral impurities.

Uses & applications

Used primarily for lapidary work, including cabochons, beads, ornamental carvings, and 'worry stones' because of its high polish and durability.

Geological facts

Jasper has been used as a gemstone since antiquity and is mentioned in many ancient texts. The name 'Fancy Jasper' specifically refers to specimens with a mottled mix of multiple colors across the surface.

Field identification & locations

Identify by its hardness (it cannot be scratched by a steel knife), smooth texture, and colorful patches. Commonly found in major deposits in India and South Africa.
