Physical properties

Hardness: 2.0-2.5 Mohs scale; Color: Honey-brown, reddish-brown; Luster: Resinous; Crystal structure: Amorphous; Cleavage: None; Specific gravity: 1.05-1.10 (very light/buoyant)

Formation & geological history

Fossilized tree resin from ancient coniferous forests, primarily dating to the Eocene epoch (about 30-50 million years ago). Formed through polymerization under anaerobic conditions in maritime or deltaic sediments.

Uses & applications

Used primarily in jewelry-making, decorative carvings, and as a source for amber acid. Highly valued by scientists for inclusions such as ancient insects and plant matter.

Geological facts

Amber is organic rather than a mineral. It can float in salt water, which is why it often washes up on beaches in the Baltic region after storms. It produces static electricity when rubbed with a cloth.

Field identification & locations

Identify by its light weight (it feels warmer and lighter than a typical stone) and its ability to float in a saturated salt water solution. Commonly found on beaches bordering the Baltic and North Seas.
