AI-generated identification · may be incorrect

Typically honey-orange, translucent, resinous luster, and irregular conchoidal fracture; Mohs hardness 2–2.5, very low density (~1.05–1.10), and no cleavage. The specimen appears naturally rough/tumbled with lighter internal flow textures.

Physical properties

Formation & geological history

Amber formed when ancient conifer or flowering-plant resin was buried, chemically altered, and hardened over roughly 20–100+ million years; major deposits occur in Paleogene sediments, especially Baltic-region deposits (~44–40 million years old).

Uses & applications

Used for beads, carvings, cabochons, ornaments, and historical medicinal or decorative objects; occasionally contains preserved insects or plant fragments.

Geological facts

Amber is organic rather than a mineral because it lacks a regular crystal structure. It can become electrostatic when rubbed and may float in saturated salt water.

Field identification & locations

Identify by its very low weight, warm feel, resinous appearance, electrostatic charging, and a pine-like odor when gently warmed; avoid destructive tests. Common sources include the Baltic coast, Dominican Republic, Mexico, Myanmar, and Sicily.
