Tumbled amber-like specimen

Amber (fossilized tree resin), commonly succinite; identification uncertain from image

AI-generated identification · may be incorrect

Translucent honey-brown, resinous luster, rounded/tumbled surface, and possible internal fractures or inclusions. Hardness is typically 2–2.5 Mohs, specific gravity about 1.05–1.10, and it lacks crystal structure and cleavage.

Physical properties

Formation & geological history

Amber formed when ancient conifer or flowering-plant resin polymerized and fossilized in sediment over millions of years, commonly from the Eocene Baltic region (~34–56 million years old) or younger deposits. The image alone cannot distinguish amber from copal, which is younger resin.

Uses & applications

Used for beads, carvings, ornaments, and jewelry; historically valued for decorative and supposed medicinal uses. It is lightweight and often warm to the touch.

Geological facts

Genuine amber may contain plant fragments or insects and can electrostatically attract small fibers after rubbing. Copal is generally softer and more soluble in solvents.

Field identification & locations

Check that it floats in concentrated salt water, becomes electrostatic when rubbed, and gives a pine-like odor when gently warmed; avoid destructive tests. Common sources include the Baltic coast, Dominican Republic, Mexico, Myanmar, and Indonesia.
