Physical properties

Hardness: 6.5-7 (Mohs); Color: Red/brick red with white/translucent veins; Luster: Dull to sub-vitreous; Structure: Cryptocrystalline; Cleavage: None, conchoidal fracture

Formation & geological history

Formed through the accumulation of fine-grained silica-rich sediments or volcanic ash that undergoes lithification. The white veins are secondary quartz deposits that filled fractures within the formed jasper over millions of years.

Uses & applications

Used primarily for lapidary work, jewelry (cabochons), ornamental decoration, and as a popular specimen for collectors and metaphysical enthusiasts.

Geological facts

The vibrant red color is caused by the inclusion of iron oxide (hematite). Jasper is an opaque variety of chalcedony and has been used since antiquity for seals and amulets.

Field identification & locations

Identify by its rich red color, opacity (it will not let light through except at thin edges), and hardness (it can scratch glass). Commonly found in riverbeds, deserts, and areas with ancient volcanic activity.
