Physical properties

Hardness: 2.0-2.5 (Mohs scale); Color: Yellow to brownish-orange; Luster: Resinous; Structure: Amorphous; Cleavage: None; Specific Gravity: 1.05-1.10 (floats in saltwater).

Formation & geological history

Formed from the fossilization of plant resins (often from ancient pine or leguminous trees) over millions of years (typically 30-90 million years old) through polymerization and burial in sedimentary layers.

Uses & applications

Used primarily in jewelry, ornamental carvings, perfumes, and for scientific research (paleontology) if inclusions like insects or plants are present.

Geological facts

Amber is not a true mineral because it is organic. It is famous for trapping Cretaceous and Tertiary period organisms in perfect detail. If rubbed with a cloth, it can produce static electricity.

Field identification & locations

Identify by its light weight, warmth to the touch (unlike cold stone), and ability to float in a saturated saltwater solution. Common in the Baltic region and Dominican Republic.
