Quartz var. Jasper (Microcrystalline Quartz) · Decorative Stone and Semi-Precious Gemstone
Crystal System
Trigonal, microcrystalline aggregate forming massive or compact habits
Mineral Group
Silicates, specifically Tectosilicates
Chemical Formula
SiO2
Formation Process
Sedimentary and hydrothermal processes involving silica-rich fluids filling fractures in rock masses, followed by cementation and consolidation
About This Crystal
Tumbled, smooth-polished specimen with an irregularly shaped cubic or blocky form. Features a rich mosaic pattern of reddish-orange, brown, and dark greyish patches interspersed with fine quartz-filled fracture veins. Opaque with a vitreous to waxy luster
Physical Characteristics
Color ranges across red, brown, orange, and black; white streak; no cleavage; conchoidal to uneven fracture; specific gravity around 2.65; brittle tenacity; inert under UV light
Optical Properties
Singly refractive aggregate, anisotropic under microscopic examination, opaque body preventing standard refractive index reading of single crystals
Hardness & Durability
Origin Region
Found globally with notable deposits in India, Russia, Brazil, Madagascar, and the USA
Hardness & Durability
Mohs hardness of 6.5 to 7, good toughness due to microcrystalline interlocking structure, very durable and highly suitable for daily jewelry wear
Care & Maintenance
Easy to care for; clean with warm soapy water and a soft cloth, avoid harsh chemical cleaners, store away from significantly harder gemstones to prevent surface scratching
Rarity & Value
Common and widely accessible, value is generally low to moderate depending on polish quality, color vibrancy, and artistic pattern appeal
Special Characteristics
Distinctive brecciated structure showing angular fragments cemented together by secondary mineral deposition, often featuring healing quartz veins
Lore & History
Historically used by ancient civilizations for amulets, talismans, and decorative tools. In modern metaphysical practices, it is traditionally associated with grounding, vitality, stability, and the root chakra
