Tumbled amber-like gemstone

Likely amber (fossilized resin; organic mineraloid), possibly citrine or yellow-brown glass imitation

AI-generated identification · may be incorrect

Small rounded, transparent honey-brown specimen with resinous to vitreous luster and internal inclusions. Amber has Mohs hardness 2–2.5, amorphous structure, low density, and no cleavage; the photograph alone cannot confirm identity.

Physical properties

Formation & geological history

True amber formed from polymerized tree resin, commonly during the Cretaceous–Cenozoic (roughly 145–2.6 million years ago), then weathered and redeposited in sediments. Major sources include the Baltic region, Dominican Republic, Myanmar, Mexico, and Indonesia.

Uses & applications

Used for beads, cabochons, carvings, ornaments, and scientific study of fossil inclusions; it is not generally used in construction or industry.

Geological facts

Amber may contain trapped insects, plant fragments, or gas bubbles and can become electrostatically charged when rubbed. A warm-needle test can damage it and is not recommended.

Field identification & locations

Identify by very low hardness, warm feel, light weight, flotation in concentrated salt water, and electrostatic attraction after rubbing; beware common copal, plastic, and glass imitations. The rounded polished form suggests a tumbled specimen.
