Amber (likely a small rough amber piece)

Fossilized plant resin; amber is an organic mineraloid, not a crystalline mineral

AI-generated identification · may be incorrect

Translucent honey-yellow to reddish brown with resinous luster and irregular fracture; hardness about 2–2.5 Mohs, amorphous, and very lightweight. The visible internal cracks and color zoning are consistent with natural resin, though an image alone cannot rule out imitation.

Physical properties

Formation & geological history

Formed as tree resin that was buried and chemically polymerized over millions of years; amber deposits range from Cretaceous to Cenozoic age. Major sources include Baltic-region deposits, Myanmar, the Dominican Republic, and Mexico.

Uses & applications

Used for beads, jewelry, carvings, and decorative objects; historically valued for ornament and occasional inclusions of ancient organisms.

Geological facts

Amber is organic rather than a conventional igneous, sedimentary, or metamorphic rock. Some specimens preserve insects, plant fragments, or air bubbles.

Field identification & locations

Look for low density, warm resinous appearance, and electrostatic charge after rubbing; avoid destructive tests on valuable pieces. Common rough pieces are often worth roughly $5–$50, with clarity, size, provenance, and inclusions greatly affecting price.
