Physical properties

Hardness: 2.0-2.5; Color: Honey-yellow, orange, or cognac brown; Luster: Resinous; Crystal structure: Amorphous; Cleavage: None; Specific Gravity: 1.05-1.10 (very lightweight, floats in saltwater).

Formation & geological history

Formed from the fossilized resin of ancient coniferous trees, primarily from the Eocene or Cretaceous periods (approx. 30-100 million years old). Over millions of years, the resin undergoes polymerization and loses volatile components.

Uses & applications

Extensively used in jewelry making (beads, pendants), as inclusions for scientific study (paleontology), and historically as an ingredient in perfumes and traditional medicines.

Geological facts

Amber is not a true mineral because it is organic. It is famous for capturing prehistoric life, such as insects, feathers, and plant matter, in perfect 3D detail. Unlike rocks, it feels warm to the touch and can generate static electricity when rubbed.

Field identification & locations

Identify in the field by its light weight, 'plastic-like' feel, and ability to float in saturated saltwater. Commonly found in the Baltic region, Dominican Republic, and Myanmar. Collectors look for clarity and the presence of rare inclusions.
