About This Crystal
Small, warm golden-yellow, rounded irregular pebble with a smooth polished surface and a resinous luster, showing translucent to transparent optical clarity.
Physical Characteristics
Color ranges from yellow, orange, to brown; white streak; no cleavage; conchoidal fracture; specific gravity around 1.05 to 1.10; brittle tenacity; can show blue or green fluorescence under UV light.
Optical Properties
Refractive index of approximately 1.54; isotropic due to amorphous structure; sometimes exhibits internal strain birefringence under polarized light.
Hardness & Durability
Origin Region
Baltic region (Poland, Russia, Lithuania), Dominican Republic, Mexico, and Myanmar
Hardness & Durability
Mohs hardness of 2 to 2.5; low toughness and easily scratched; sensitive to heat, organic solvents, and prolonged direct sunlight.
Care & Maintenance
Clean only with a soft, damp cloth and mild soapy water; do not use ultrasonic or steam cleaners; store separately from harder gems to avoid scratching.
Rarity & Value
Common to Uncommon depending on clarity, size, and presence of fossil inclusions; value increases significantly with insect or plant inclusions.
Special Characteristics
Often contains trapped prehistoric insects, plant parts, or air bubbles (enhydros); exhibits strong electrostatic properties when rubbed.
Lore & History
Used since the Stone Age for ornamentation and trade; long associated with solar energy, protection, emotional healing, and clearing negative energy in traditional lore.
