Physical properties

Formation & geological history

Amber formed from tree resin that was buried, chemically altered, and lithified over tens of millions of years, commonly during the Cretaceous–Cenozoic (roughly 20–140+ million years old). Major deposits occur in Baltic-region sediments, the Dominican Republic, Myanmar, Mexico, and Indonesia.

Uses & applications

Used for beads, cabochons, carvings, ornaments, and collectible specimens; historically used as incense and decorative material. It is not a construction rock.

Geological facts

Amber may contain preserved insects, leaves, or air bubbles, though none is clearly visible here. Warmth, static attraction after rubbing, and a pine-like odor when gently heated can support identification, but destructive tests are best avoided.

Field identification & locations

Identify by its very low weight, warm feel, resinous appearance, softness, and ability to float in concentrated salt water; distinguish it from copal, plastic, and glass. Common tumbled pieces are worth about $5–$30; clearer, larger, or inclusion-rich amber may range from $50 to thousands.
