Physical properties

Smooth, rounded, translucent-to-opaque golden-brown surface with a glossy polish; no crystal structure is visible. The image is insufficient to determine hardness or confirm the material.

Formation & geological history

If amber, it formed from ancient plant resin and was later buried and fossilized, commonly during the Cretaceous or Tertiary. The specimen’s identity and age cannot be established from the photograph alone.

Uses & applications

Amber is used in jewelry and collecting; similar-looking materials include other gemstones and imitation resin.

Geological facts

A warm glow and apparent inclusions can occur in amber but are not diagnostic; plastic and glass imitations are common.

Field identification & locations

The image shows a polished cabochon, but tests such as specific gravity, UV response, and examination of inclusions are needed for identification. Amber occurs in deposits including the Baltic region and the Dominican Republic.
