Physical properties

Hardness: 2.0-2.5 on Mohs scale; Color: Honey yellow to reddish brown; Luster: Resinous; Crystal structure: Amorphous; Cleavage: None; Specific gravity: 1.05-1.10

Formation & geological history

Fossilized tree resin from ancient coniferous forests, primarily dating from the Cretaceous to the Eocene (approx. 40-60 million years ago); formed through polymerization under heat and pressure.

Uses & applications

Highly prized in jewelry (beads, pendants), as a source of succinic acid, and as a valuable specimen for paleontology when containing inclusions.

Geological facts

Amber is one of the few organic gemstones. It can preserve ancient DNA, insects, and plant matter for millions of years. The world's largest deposit is located in the Baltic Sea region.

Field identification & locations

Identify by its low density (it can float in saltwater), warm touch compared to glass, and faint pine scent when rubbed vigorously or touched with a hot needle. Found in sedimentary deposits.
