Polished fossil-bearing amber cabochon (likely insect inclusion)

Fossilized plant resin; commonly Dominican or Baltic amber, chemically a complex diterpenoid resin

AI-generated identification · may be incorrect

Transparent honey-yellow to orange resin with a glossy polish and a dark inclusion resembling an insect or plant fragment. Mohs hardness about 2–2.5, low density (~1.05–1.10), amorphous rather than crystalline, and resinous luster; the metal ring is not geological.

Physical properties

Formation & geological history

Amber formed when ancient tree resin hardened and was buried, polymerizing over millions of years; Dominican amber is commonly Miocene (about 15–20 million years old), while Baltic amber is mainly Eocene (about 34–56 million years old).

Uses & applications

Used for jewelry, cabochons, ornaments, and fossil-inclusion collecting. Attractive, well-preserved insect inclusions can command substantially higher prices.

Geological facts

The specimen appears to be a polished amber cabochon set in a ring or holder; its inclusion may be a fossil insect, but the image is insufficient for precise identification. Amber often becomes electrostatically charged when rubbed and may fluoresce under UV light.

Field identification & locations

Identify by very low weight, warm resinous feel, scratchability, and possible flotation in saturated salt water; distinguish from glass by its lower hardness and from plastic by careful examination and testing. Common sources include the Dominican Republic, Baltic region, Myanmar, and Mexico.
