Garnet (specifically Almandine or Pyrope)
Almandine Garnet (IMA approved species) · Semi-Precious Gemstone / Decorative Carving
Crystal System
Cubic (Isometric); typical dodecahedral habit but here presented in a carved, nine-tailed fox (kitsune) form
Mineral Group
Silicates (Subgroup: Nesosilicates)
Chemical Formula
Fe3Al2(SiO4)3 (with common Mg or Mn trace substitutions)
Formation Process
Metamorphic formation under high pressure and temperature in regional metamorphic belts; also found in igneous pegmatites
About This Crystal
Deep brownish-red to nearly black material with a vitreous to resinous luster. It is translucent to opaque in this thickness, showing deep red internal flashes under strong direct light (backlighting). The carving displays a smooth, polished surface with minor visible grain boundaries.
Physical Characteristics
Color: Dark burgundy red; Streak: White; Cleavage: None (distinct parting sometimes present); Fracture: Conchoidal to uneven; Specific Gravity: 3.7 to 4.3; Fluorescence: Generally inert under UV light
Optical Properties
Refractive Index: 1.770–1.810 (Isotropic); Singly refractive; No pleochroism; High dispersion but masked by dark body color in this specimen
Hardness & Durability
Origin Region
India, Madagascar, Sri Lanka, or Brazil; typically found in metamorphic schists and gneisses
Hardness & Durability
Mohs hardness: 6.5–7.5; Good toughness due to lack of cleavage, making it very durable for jewelry and carvings
Care & Maintenance
Clean with warm soapy water; safe for ultrasonic cleaners if no liquid-filled inclusions; avoid sudden extreme temperature changes; generally stable in sunlight
Rarity & Value
Common; value for this specimen is dictated by carving artistry rather than gemstone clarity. Small carvings typically range from $15 to $50 USD depending on detail
Special Characteristics
Deep red 'fire' visible when held to light despite the dark appearance (back-lighting effect); may contain needle-like rutile inclusions causing slight silkiness
Lore & History
Historically used in the Bronze Age as gemstones and abrasives. Ancient Romans used garnet signet rings. Symbolizes strength, protection, and the root chakra in traditional crystal lore; often associated with January 'birthstone' traditions.
