Physical properties

Hardness: 2.0-2.5 on Mohs scale; Color: Yellow, orange, or golden-brown; Luster: Resinous; Crystal structure: Amorphous; Cleavage: None (conchoidal fracture); Specific gravity: 1.05-1.10.

Formation & geological history

Formed through the polymerization and fossilization of tree resin over millions of years (principally from the Eocene or Cretaceous periods), typically found in sedimentary deposits.

Uses & applications

Primarily used in jewelry, decorative arts, and as a scientific medium for studying prehistoric life trapped within inclusions.

Geological facts

Amber is organic in origin and can float in salt water. It is known for its ability to preserve ancient insects and plant matter in exquisite detail for millions of years.

Field identification & locations

Identify in the field by its light weight (low density), warm feel compared to stone, and the ability to produce a pine-like scent when touched with a hot needle. Found commonly in the Baltic region, Dominican Republic, and Myanmar.
