Physical properties

Hardness: 6.5-7 Mohs. Color: Red/terracotta with white quartz veining. Luster: Dull to waxy. Structure: Cryptocrystalline. Opaque with a smooth, almost soapy feel when weathered.

Formation & geological history

Formed primarily in sedimentary environments where silica-rich fluids permeate through beds of volcanic ash or silicate rocks, often during the Precambrian or Paleozoic eras. The white veins are secondary quartz infillings in fractures.

Uses & applications

Used extensively for lapidary work, cabochons, decorative carvings, and in metaphysical collections as a grounding stone.

Geological facts

Red Jasper gets its color from high concentrations of iron oxide (hematite). It has been used since antiquity for seals, talismans, and jewelry due to its hardness and vibrant color.

Field identification & locations

Identify by its deep red color, high hardness (cannot be scratched by a steel knife), and characteristic quartz spiderweb veining. Common in riverbeds and mountainous regions globally.
