Red Jasper with Quartz Veins
Quartz var. Jasper · Semi-Precious Gemstone and Mineral Specimen
Crystal System
Trigonal, massive microcrystalline habit
Mineral Group
Silicates
Chemical Formula
SiO2
Formation Process
Sedimentary or hydrothermal precipitation of silica-rich fluids filling fractures in host rock, followed by microcrystalline quartz formation.
About This Crystal
An opaque, brick-red to brownish-red microcrystalline quartz specimen characterized by distinctive white to clear hydrothermal quartz veins webbing across the surface.
Physical Characteristics
Brick-red and white color, white streak, conchoidal fracture, lack of cleavage, specific gravity of approximately 2.58 to 2.91, vitreous to dull waxy luster.
Optical Properties
Singly refractive aggregate (microcrystalline), though individual quartz grains are doubly refractive; non-pleochroic and opaque.
Hardness & Durability
Origin Region
Found globally; notable sources include India, Madagascar, Brazil, Russia, and the USA. Typically forms in sedimentary environments and volcanic regions.
Hardness & Durability
Mohs hardness of 6.5 to 7, high toughness and durability making it very stable and well-suited for various types of jewelry and decorative objects.
Care & Maintenance
Clean with warm soapy water and a soft brush; store separately from softer materials to avoid scratching; highly resistant to standard household chemicals.
Rarity & Value
Common and widely available, with inexpensive pricing largely determined by the aesthetic appeal of the veining, polish, and size.
Special Characteristics
Features prominent white quartz veinlets creating a contrasting network pattern across a dense red jasper matrix.
Lore & History
Historically used by ancient civilizations including the Egyptians, Greeks, and Native Americans for talismans and seals. In modern metaphysical practices, red jasper is traditionally associated with vitality, grounding, and the root chakra, though these are cultural beliefs rather than scientifically verified claims.
