Amber

Fossilized tree resin; primarily an organic polymer of terpenoid compounds (succinite when Baltic-type)

AI-generated identification · may be incorrect

Honey-brown, translucent resin with waxy to resinous luster and conchoidal fracture; amorphous, Mohs hardness about 2–2.5, specific gravity roughly 1.05–1.10. The surface appears polished or naturally smoothed, though exact identification cannot be confirmed from an image alone.

Physical properties

Formation & geological history

Produced as tree resin, commonly from ancient conifers, then buried and chemically matured over roughly 2–50+ million years. Major deposits occur in Eocene Baltic sediments, Dominican Republic, Myanmar, and Mexico.

Uses & applications

Used for beads, cabochons, carvings, ornaments, and collecting; historically used as incense and decorative material. It is too soft for most industrial or structural applications.

Geological facts

Amber can contain preserved insects, plant fragments, and air bubbles. It often floats in concentrated salt water and may develop an electrostatic charge when rubbed.

Field identification & locations

Check for low density, warm feel, softness, and electrostatic attraction; UV fluorescence is common. Plastic imitations may smell chemical, deform more readily with heat, or show flow lines; prices range from about $5–$50 for common pieces to $100–$1,000+ for large, clear, inclusion-rich specimens.
