Amber

Fossilized tree resin (mainly polymerized diterpenoid resin)

AI-generated identification · may be incorrect

Usually Mohs hardness 2–2.5, very low density (about 1.05–1.10), resinous luster, translucent orange-brown color, and no crystal structure or cleavage. It may feel warm, float in salt water, and produce a resinous scent when gently warmed.

Physical properties

Formation & geological history

Amber formed from plant resin exuded primarily by ancient conifers and flowering trees, then buried and polymerized over millions of years; most commercial amber is Cretaceous to Neogene in age. The specimen’s orange translucent appearance is consistent with amber, though exact identification requires testing.

Uses & applications

Used for beads, carvings, jewelry, ornaments, and scientific inclusions; it is also collected for insects or plant fragments preserved inside. It has little industrial value beyond decorative use.

Geological facts

Amber can preserve remarkably detailed fossils and may fluoresce blue, green, or yellow under ultraviolet light. Baltic amber is among the best-known varieties.

Field identification & locations

Common sources include the Baltic region, Dominican Republic, Mexico, Myanmar, and Indonesia. Check low density, static attraction after rubbing, warm feel, and a subtly irregular natural surface; plastic imitations are harder and often smell chemical when heated.
