Tumbled amber (likely)

Amber; fossilized plant resin, commonly succinite (organic material rather than a mineral)

AI-generated identification · may be incorrect

Small, rounded translucent yellow-brown piece with resinous/waxy luster and apparent internal cloudiness. Hardness is about 2–2.5 Mohs, specific gravity about 1.05–1.10; it is amorphous, lacks cleavage, and is easily scratched. The image alone cannot exclude yellow copal or colored glass.

Physical properties

Formation & geological history

Amber formed from ancient tree resin that was buried, polymerized, and hardened over millions of years, commonly during the Cretaceous–Neogene. Major sources include Baltic-region deposits, the Dominican Republic, Myanmar, Mexico, and Indonesia.

Uses & applications

Used for beads, carvings, cabochons, ornaments, and scientific inclusions; historically used as incense and decorative material. Quality depends on clarity, color, size, and inclusions.

Geological facts

Amber often contains insects, plant fragments, or gas bubbles and becomes electrostatically charged when rubbed. Copal is younger, softer resin and a common amber imitation.

Field identification & locations

Check that it floats in concentrated salt water, feels warm rather than cold, and produces a pine-like odor when gently warmed; amber may fluoresce blue-white under UV. Avoid destructive tests and strong heat.
