Polychrome Jasper
Microcrystalline Quartz var. Jasper · Decorative Stone and Mineral Specimen
Crystal System
Trigonal, shaped into a fabricated multi-faceted polished tower or obelisk
Mineral Group
Silicates
Chemical Formula
SiO2
Formation Process
Sedimentary or hydrothermal precipitation of silica-rich fluids filling cavities in volcanic rocks, forming microcrystalline quartz masses with various mineral impurities over millions of years
About This Crystal
An expertly carved and polished tower featuring distinct, vibrant banding and patches of slate grey, earthy brown, terracotta orange, cream, and deep red. The surface has a high-gloss vitreous polish showing smooth transitions between different jasper matrix types.
Physical Characteristics
Opaque transparency, vitreous to waxy luster, conchoidal fracture, lack of visible cleavage, specific gravity of approximately 2.58 to 2.91, white streak, and strong resistance to scratching.
Optical Properties
Singly or microcrystalline doubly refractive aggregate, generally no pleochroism due to the cryptocrystalline nature, opaque with rich varied color blocking.
Hardness & Durability
Origin Region
Madagascar, specifically the Desert of Ambanja
Hardness & Durability
Mohs hardness of 6.5 to 7, excellent toughness due to the microgranular interlocking structure, making it durable for handling and display.
Care & Maintenance
Easily cleaned with warm, soapy water and a soft cloth; avoid harsh chemical cleaners, prolonged direct sunlight to prevent surface fading, and store separately to avoid scratching softer surrounding items.
Rarity & Value
Uncommon to rare depending on the exact color vibrancy and pattern uniqueness; high-quality Polychrome Jasper from Madagascar commands moderate collector value, with prices varying based on size and carving polish.
Special Characteristics
Vibrant natural color blocking and mixing of multiple mineral zones within a single microcrystalline quartz matrix, creating landscape-like or abstract artistic patterns.
Lore & History
Often associated with deep grounding, connection to the earth, stability, and vitality in contemporary crystal healing traditions, though these are symbolic beliefs rather than scientifically validated claims.
