Physical properties
Hardness of 7 on the Mohs scale, deep reddish-brown with contrasting white quartz veins, vitreous luster, microcrystalline structure.
Formation & geological history
Formed via hydrothermal precipitation where silica-rich fluids filled fractures in pre-existing iron-rich sedimentary rock.
Uses & applications
Used primarily in lapidary arts, decorative cabochons, and as a popular specimen for mineral collectors.
Geological facts
Jasper is an ancient variety of chalcedony historically used to create seals, talismans, and decorative ornaments.
Field identification & locations
Easily identified by its conchoidal fracture and distinct hardness; commonly found in riverbeds and mountainous terrain.
