Physical properties

Hardness: 6.5-7 (Mohs); Color: Red, white, and translucent gray; Luster: Vitreous to waxy when polished; Structure: Trigonal/Microcrystalline; Cleavage: None (conchoidal fracture).

Formation & geological history

Formed from the deposition of silica in hydrothermal veins or as a chemical sedimentary rock in iron-rich environments. The red color is caused by iron (hematite) impurities.

Uses & applications

Commonly used for lapidary work, decorative carvings (like this egg shape), jewelry, and by collectors for its aesthetic patterns.

Geological facts

Red jasper has been used since antiquity for royal seals and amulets. It is often called the 'stone of endurance' in metaphysical circles.

Field identification & locations

Identify by its opacity (jasper is generally opaque compared to translucent chalcedony), hardness (cannot be scratched by a steel blade), and distinctive red-and-white brecciated or mottled pattern.
