About This Crystal
An intricately carved figurative sculpture, resembling a traditional Japanese netsuke depicting an elderly man holding a sack. The material is creamy off-white to yellowish-beige with subtle natural grain lines and a warm, waxy luster.
Physical Characteristics
Color: Cream to yellowish white. Streak: White. Cleavage: None (fibrous/granular fracture). Specific Gravity: Approximately 1.7-2.0. Tenacity: Tough and resilient. Luster: Vitreous to dull waxy, developing a patina over time.
Optical Properties
Translucent to opaque in thicker sections. Isotropic to weakly birefringent due to microcrystalline hydroxyapatite composition.
Hardness & Durability
Origin Region
Derived from elephant, mammoth, or marine mammal tusks; typically carved in East Asia (Japan, China)
Hardness & Durability
Mohs Hardness: 2.5 to 3.0. Durable for gentle handling as a carving, but soft and susceptible to scratching, severe impacts, and chemical degradation.
Care & Maintenance
Clean with a soft, damp cloth. Avoid harsh chemicals, soaps, ultrasonic cleaners, and excessive heat or dryness which can cause cracking and warping.
Rarity & Value
Valuable antique or collectible artwork depending on age, carver, and provenance. Modern trade of new elephant ivory is strictly regulated or banned globally to protect wildlife.
Special Characteristics
Exhibits Schreger lines (cross-hatching patterns unique to ivory) under magnification, giving it a distinctive organic fingerprint.
Lore & History
Historically used across many cultures for luxury items, imperial artifacts, and miniature garments toggles (netsuke). In modern holistic or metaphysical traditions, organic materials are sometimes associated with grounding, ancestral connection, and life force, though this is traditional lore rather than scientific fact.
