Amber
Fossilized Tree Resin (Amber) · Organic Gem
Crystal System
Amorphous (Non-crystalline)
Mineral Group
Organic Mineraloid
Chemical Formula
C10H16O (Variable organic polymer)
Formation Process
Fossilization of tree resin through burial, loss of volatile organic compounds, and polymerization over millions of years
About This Crystal
A polished, smooth, tumbled organic gemstone displaying a mix of deep dark brown to black areas alongside translucent golden-yellow and greenish zones, featuring internal golden reflections and organic inclusions
Physical Characteristics
Color ranges from yellow, orange, brown to rare blue and green; white streak; no cleavage; conchoidal fracture; very low specific gravity (1.05-1.10, floats in salt water); brittle tenacity; exhibits strong blue fluorescence under UV light
Optical Properties
Isotropic (amorphous); refractive index of approximately 1.54; weak double refraction is sometimes observed due to internal stress; strong resinous luster
Hardness & Durability
Origin Region
Dominican Republic, Baltic region (Poland, Russia), Mexico, Myanmar
Hardness & Durability
Mohs hardness of 2 to 2.5; poor toughness; highly sensitive to heat, solvents, and alcohol; scratches easily and requires gentle wear and care
Care & Maintenance
Clean only with a soft, damp cloth and mild soapy water; do not use ultrasonic or steam cleaners; store separately from harder stones to avoid scratching; protect from perfumes, hairsprays, and prolonged direct sunlight
Rarity & Value
Common to Uncommon, with blue and green amber being rare and highly valuable; value is determined by clarity, color, size, and particularly the presence of preserved biological inclusions like insects or plants
Special Characteristics
Famous for containing trapped prehistoric inclusions (insects, flora, air bubbles); exhibits strong blue fluorescence under ultraviolet light due to hydrocarbon composition; can accumulate static electricity when rubbed
Lore & History
Used since the Stone Age for jewelry and talismans; historically traded along the ancient Amber Road; symbolically associated with solar energy, renewal, and cleansing; in metaphysical practices, it is believed to absorb negative energy and promote emotional well-being (traditional beliefs, not scientific claims)
