Physical properties
Hardness: 6.5-7 on Mohs scale; Color: Deep brownish-red to dark red; Luster: Vitreous to waxy when polished; Crystal Structure: Trigonal (microcrystalline quartz/chalcedony); Cleavage: None (conchoidal fracture).
Formation & geological history
Formed through precipitation of silica-rich fluids in volcanic ash or sedimentary rocks, with red coloration coming from iron oxide (hematite) inclusions incorporated during crystallization.
Uses & applications
Widely used in jewelry (pendants, beads, rings), lapidary art, carvings, and metaphysical/crystal healing practices.
Geological facts
Red Jasper has been used since antiquity; it was revered by ancient Egyptians as a stone of protection and was often carved into amulets and scarabs.
Field identification & locations
Identified by its rich opaque red-brown color, high hardness, smooth waxy polish, and absence of cleavage. Commonly found in Brazil, India, South Africa, Madagascar, and the USA.
