Amber cabochon or polished amber-like material

Amber (fossilized plant resin), chiefly C10H16O; possibly resin imitation

AI-generated identification · may be incorrect

Translucent honey-brown to yellow, resinous luster, amorphous rather than crystalline, Mohs hardness about 2–2.5, very low density (about 1.05–1.10), and no cleavage. The rounded, highly polished appearance suggests a cabochon or tumbled piece; the image is too blurred to confirm natural amber.

Physical properties

Formation & geological history

Amber formed when ancient conifer or flowering-plant resin was buried, polymerized, and preserved in sediment, commonly during the Cretaceous–Tertiary (roughly 5–145 million years ago). Major deposits occur in Baltic-region sediments, Myanmar, the Dominican Republic, Mexico, and Indonesia.

Uses & applications

Used for beads, cabochons, carvings, ornaments, and insect-inclusion jewelry; small pieces are also collected. It has limited industrial use.

Geological facts

Amber commonly floats in salt water, becomes electrostatic when rubbed, and softens or gives a pine-like odor when gently warmed—tests should be conservative to avoid damage.

Field identification & locations

Field identification includes exceptional lightness, warm touch, resinous appearance, and possible bubbles or inclusions; distinguish it from copal and plastic with density, UV response, and professional testing. Common sources include Baltic and Dominican deposits.
