Amber

Physical Properties

Hardness: 2.0-2.5 on Mohs scale; Color: Honey-yellow, orange, reddish-brown; Luster: Resinous; Crystal structure: Amorphous; Gravity: 1.05-1.10 (very light)

Formation & Geological History

Fossilized plant resin from ancient coniferous or angiosperm trees, typically dating from the Cretaceous to the Neogene periods (approx. 30-90 million years old).

Uses & Applications

Used extensively in jewelry (beads, pendants), as a gemstone, and in scientific research to study prehistoric inclusions like insects or plant matter.

Geological Facts

Amber is one of the few organic decorative materials. It can float in saltwater and becomes electrostatic when rubbed, a property that led to the discovery of static electricity.

Field Identification & Locations

Identified by its low density, resinous feel, and warm touch. Found in coastal deposits or mines in the Baltic region, Dominican Republic, and Myanmar. Use a 'hot needle' test to smell the resin.
