Red Jasper
Quartz var. Jasper (Microcrystalline Quartz / Chalcedony) · Semi-Precious Gemstone / Decorative Stone
Crystal System
Trigonal (Hexagonal); usually found in massive or microcrystalline habits. This specimen has been artificially cut into a six-sided (hexagonal) prismatic wand with a terminated point.
Mineral Group
Silicates (Tectosilicate group); a variety of Chalcedony.
Chemical Formula
SiO2 (Silicon Dioxide) with Fe2O3 (Iron Oxide/Hematite) inclusions typically responsible for the red coloration.
Formation Process
Sedimentary or Hydrothermal; forms when silica-rich fluids deposit in cracks, cavities, or as a replacement for organic material or other minerals. The red color is caused by the presence of iron oxide disseminated throughout the silica matrix.
About This Crystal
An opaque, microcrystalline stone exhibiting a deep brick-red to terracotta color with visible mottling and dark grey or black inclusions (likely hematite or magnetite). The surface shows a vitreous to earthy luster when polished, as seen in this cut wand shape.
Physical Characteristics
Color: Red (brick-red); Streak: White or colorless; Cleavage: None; Fracture: Conchoidal to splintery; Specific Gravity: 2.58–2.91; Tenacity: Brittle but tough; Magnetism: Generally non-magnetic though inclusions can sometimes be weakly magnetic.
Optical Properties
Refractive Index: 1.54; Birefringence: None (aggregate); Pleochroism: Absent; Luster: Vitreous when polished; Diaphaneity: Opaque.
Hardness & Durability
Origin Region
Globally distributed; major sources include South Africa, Brazil, India, USA, and Australia. Often found in hydrothermal veins and sedimentary environments.
Hardness & Durability
Mohs Hardness: 6.5 to 7. Excellent durability and toughness due to its microcrystalline structure, making it highly suitable for jewelry and decorative wands.
Care & Maintenance
Clean with warm soapy water and a soft brush. While resistant to many chemicals, avoid harsh acids. Store separately from harder stones like sapphire or diamond to prevent scratching.
Rarity & Value
Common. Inexpensive and widely available. Value factors include the saturation of the red color and the presence of aesthetic patterns or contrasting inclusions. Treatments are rare for Red Jasper.
Special Characteristics
Displays an opaque 'earthy' appearance unlike transparent quartz. It frequently contains dark vein-like inclusions of iron ores or other minerals that create unique patterns.
Lore & History
Historically known as a 'warrior's stone' in ancient cultures, including Ancient Egypt and Greece, where it was linked to the deity Isis or Mars. In modern crystal healing, it is associated with the Root Chakra and believed to provide grounding, endurance, and physical strength.
