Quartz var. Jasper (Mookaite) · Decorative Stone / Semi-Precious
Crystal System
Trigonal, microcrystalline habit forming in massive or nodular masses
Mineral Group
Silicates
Chemical Formula
SiO2 with various impurities like iron oxides
Formation Process
Sedimentary formation through the weathering of radiolarian skeletons accumulating in marine environments, later silicified.
About This Crystal
An elongated, polished slab displaying distinct banded and swirling patterns in earthy tones of red, burgundy, cream, yellow, and mauve. The surface is smooth and semi-vitreous to waxy, completely opaque, highlighting intricate flow-like sedimentary layers.
Physical Characteristics
Colors include brick red, mustard yellow, cream, and mauve; streak is white; cleavage is none; fracture is conchoidal; specific gravity is approximately 2.58 to 2.91; tenacity is brittle; non-magnetic.
Optical Properties
Refractive index ranges from 1.544 to 1.553; doubly refractive (microcrystalline); non-pleochroic; completely opaque with no chatoyancy or asterism.
Hardness & Durability
Origin Region
Mooka Creek, Western Australia
Hardness & Durability
Mohs hardness of 6.5 to 7; good toughness and durability, making it highly suitable for cabochons, slabs, and various jewelry applications without major cleavage concerns.
Care & Maintenance
Clean with warm soapy water and a soft cloth; avoid harsh chemical cleaners, prolonged direct sunlight to prevent potential color dulling, and store separately to avoid scratching softer materials.
Rarity & Value
Uncommon, sourced primarily from a single specific region in Australia. Value depends on color vibrancy, pattern complexity, and size. Generally affordable to moderate price range.
Special Characteristics
Distinctive multi-colored flow patterns created by ancient radiolarian deposits, exhibiting rich organic-looking banding and a porcelain-like fracture.
Lore & History
Discovered relatively recently along Mooka Creek in Western Australia, it has gained popularity in modern crystal healing as a stone of strength, vitality, and decision-making, though these remain traditional beliefs rather than scientific claims.
