About This Crystal
An opaque, fine-grained microcrystalline quartz specimen displaying rich red and pale pinkish-white banded or mottled color zones with a dull to vitreous luster
Physical Characteristics
Color ranges from brick red to brownish-red with white quartz bands; streak is white; cleavage is absent; fracture is conchoidal to uneven; specific gravity is approximately 2.65; tenacity is brittle
Optical Properties
Singly refractive aggregate under polariscope, though individual micro-crystals are doubly refractive; birefringence is hidden by microcrystalline structure; pleochroism is none
Hardness & Durability
Origin Region
Found globally; notable sources include India, Brazil, Russia, Madagascar, and the USA
Hardness & Durability
Mohs hardness of 6.5 to 7; good toughness and durability making it highly suitable for lapidary work and jewelry
Care & Maintenance
Clean with warm soapy water and a soft cloth; avoid harsh chemicals and prolonged exposure to extreme heat; store separately to prevent scratching softer stones
Rarity & Value
Common and widely available; value is generally low to moderate, determined by color intensity, pattern uniqueness, and size; enhancements are rare since natural material is abundant
Special Characteristics
Opaque microcrystalline nature containing up to 20 percent foreign materials, primarily iron oxides which account for the dense red coloration
Lore & History
Historically used by ancient civilizations including the Egyptians and Native Americans for amulets, seals, and weaponry; traditionally associated with grounding, vitality, and the root chakra in modern crystal healing lore
