About This Crystal
The specimen is shaped into a cut and polished terminated hexagonal pendant. It exhibits a uniform pale yellow to cream color with a smooth, waxy luster and opaque to sub-translucent transparency.
Physical Characteristics
Color: Pale yellow. Streak: White. Cleavage: None distinct in massive forms. Fracture: Conchoidal to uneven. Specific Gravity: Approximately 2.65 for quartz-based stones. Tenacity: Brittle to tough.
Optical Properties
Uniaxial positive (for quartz); refractive index around 1.54 - 1.55; non-pleochroic in massive forms.
Hardness & Durability
Origin Region
Global distribution; commonly sourced from China, Myanmar, Brazil, and the USA
Hardness & Durability
Mohs hardness of 7 (if quartz) or 6 (if nephrite jade); good toughness, suitable for everyday jewelry wear.
Care & Maintenance
Clean with warm soapy water and a soft brush. Avoid harsh chemical cleaners, ultrasonic cleaners, and prolonged exposure to direct sunlight.
Rarity & Value
Common; widely available in commercial jewelry markets at affordable price points.
Special Characteristics
Often dyed or heat-treated to enhance the yellow coloration if the base material is common white quartz or chalcedony.
