Physical properties

Hardness: 2.0-2.5; Color: Honey yellow, orange, brown; Luster: Resinous; Crystal structure: Amorphous; Cleavage: None; Specific gravity: 1.05-1.10 (low density, floats in salt water)

Formation & geological history

Formed through the polymerization of plant resins from ancient coniferous or angiosperm trees over millions of years (typically Eocene to Cretaceous periods) through burial and anaerobic pressure.

Uses & applications

Used primarily in jewelry (beads, cabochons), decorative arts, and as a scientific medium for preserving prehistoric biological inclusions (insects, feathers).

Geological facts

Amber is not a true mineral because it is organic and lacks a crystalline structure. It is famous for trapping well-preserved prehistoric organisms and is the basis for the fictional concept of 'Jurassic Park'.

Field identification & locations

Identify in the field by its light weight, warmth to the touch, and ability to generate static electricity when rubbed. Found commonly in the Baltic region and Dominican Republic. Collectors look for clarity and rare inclusions.
