Physical properties

Hardness: 6.5-7 (Mohs); Color: Dark green with lighter green or white banding; Luster: Vitreous to waxy; Structure: Microcrystalline (Trigonal); Cleavage: None; Fracture: Conchoidal

Formation & geological history

Formed from compressed volcanic ash or silica-rich sediment. The banding is created by the rhythmic precipitation of different minerals, primarily iron or manganese oxides, over millions of years.

Uses & applications

Used primarily for ornamental purposes, jewelry (beads, cabochons), carvings, and as a popular collecting stone for its unique patterns.

Geological facts

Despite being called 'Jasper', it is technically an opaque variety of chalcedony. It is often referred to as 'The Stone of Balance' in metaphysical circles due to its contrasting bands.

Field identification & locations

Identify by its distinct opaque bands and high hardness (it cannot be scratched by a steel knife). Commonly found in Australia, Russia, and Africa. Often found in riverbeds or concentrated deposits.
