Polychrome Jasper
Microcrystalline Quartz var. Jasper · Decorative Stone / Ornamental Mineral Specimen
Crystal System
Trigonal (Cryptocrystalline Quartz)
Mineral Group
Silicates (Tectosilicate subgroup)
Chemical Formula
SiO2
Formation Process
Sedimentary or hydrothermal precipitation of silica-rich fluids filling cavities or fractures in volcanic rocks, often combined with iron oxides and other mineral impurities.
About This Crystal
An opaque, microcrystalline quartz specimen cut and polished into a modern tower shape. It features a striking and vibrant natural color palette including bands of cream, tan, deep red, ochre yellow, and dark brown. The polished surface displays a vitreous to waxy luster, showcasing intricate natural banding and contrasting color blocks typical of multi-colored jasper.
Physical Characteristics
Opaque transparency; body color is multicolored with predominant bands of cream, yellow, red, and brown; white streak; no true cleavage, exhibits conchoidal to uneven fracture; specific gravity is approximately 2.58 to 2.91; brittle tenacity; non-magnetic.
Optical Properties
Singly or micro-doubly refractive aggregate, but individual crystals are too small to resolve; generally inert under ultraviolet light; no pleochroism, chatoyancy, or play of color.
Hardness & Durability
Origin Region
Madagascar (specifically the Ampanihy region), also found in parts of the USA, Australia, and India
Hardness & Durability
Mohs hardness of 6.5 to 7; good toughness due to its microcrystalline interlocking structure; stable under normal environmental conditions, resistant to household chemicals and scratching by most common materials.
Care & Maintenance
Clean with warm soapy water and a soft cloth; avoid harsh acids or abrasive cleaners; store separately from softer gems and away from prolonged, intense direct sunlight to prevent surface dulling.
Rarity & Value
Common to Uncommon depending on the vibrancy of the color patterns; value is determined by aesthetic appeal, contrast, and size; typically affordable to moderate price range for polished ornamental towers.
Special Characteristics
Distinctive natural polychromatic banding and contrasting color blocking caused by varying iron oxide and mineral inclusions during formation.
Lore & History
Popular in modern crystal healing and decorative practices. Often associated with stability, grounding, connection to the earth, and vitality. Traditionally linked to the root and sacral chakras, though these are cultural and metaphysical beliefs rather than scientific claims.
