Red Jasper
Quartz var. Jasper · Decorative Stone and Semi-Precious Gemstone
Crystal System
Trigonal, microcrystalline aggregate forming massive or compact habits
Mineral Group
Silicates, specifically Tectosilicates
Chemical Formula
SiO2 with iron oxide impurities
Formation Process
Sedimentary or hydrothermal processes, typically forming from silica-rich solutions precipitating in cracks, cavities, or as deposits in marine environments, often rich in iron oxides
About This Crystal
A smooth, tumbled stone exhibiting a rich brick-red to brownish-red color with darker brownish mottling and subtle banding. It has an opaque transparency and a waxy to vitreous luster typical of polished microcrystalline quartz.
Physical Characteristics
Opaque red to brownish-red body color with a white streak. It has no true cleavage, breaking with a smooth conchoidal to uneven fracture. The specific gravity is approximately 2.65 to 2.68, and tenacity is brittle.
Optical Properties
Uniaxial positive with aggregate birefringence; singly or weakly doubly refractive under microscopic examination due to microcrystalline structure. Displays no pleochroism or special optical phenomena.
Hardness & Durability
Origin Region
Found worldwide, with notable deposits in India, Brazil, Russia, France, Germany, and the United States
Hardness & Durability
Mohs hardness of 6.5 to 7. Excellent toughness and stability, making it highly durable and well-suited for everyday jewelry wear without significant risk of scratching or damage.
Care & Maintenance
Very easy to care for. Can be cleaned safely using warm soapy water and a soft brush. Avoid harsh chemical cleaners and prolonged exposure to extreme heat, though it is generally stable in sunlight.
Rarity & Value
Common and widely accessible. Value is generally very low, making tumbled stones and decorative carvings quite affordable, typically ranging from a few dollars upwards depending on size and polish quality.
Special Characteristics
Displays dense, opaque microcrystalline structures with characteristic iron oxide inclusions giving it the rich red coloration. May occasionally show faint banding or patterns typical of jasper varieties.
Lore & History
Historically used by ancient civilizations including the Egyptians, Greeks, and Romans for amulets, seals, and talismans, often associated with strength, grounding, and endurance. In modern crystal healing, it is traditionally linked to the root chakra and believed to promote vitality and emotional stability.
