Amber

Physical Properties

Hardness: 2.0-2.5 Mohs; Color: Golden yellow to honey brown; Luster: Resinous; Crystal structure: Amorphous; Specific gravity: 1.05-1.09; Fracture: Conchoidal

Formation & Geological History

Formed through the fossilization of resin from extinct coniferous trees, primarily Pinus succinifera. Most commercial specimens are from the Baltic region and date back to the Eocene epoch (approx. 44 million years ago).

Uses & Applications

Primarily used in jewelry, decorative arts, and as a source for amber acid. It is highly valued by paleontologists when it contains inclusions like prehistoric insects.

Geological Facts

Amber is not a true mineral because it is organic and lacks a crystalline structure. It is famous for capturing extinct life forms in 'frozen' detail, which was the scientific premise for the Jurassic Park novel and film.

Field Identification & Locations

Identify in the field by its light weight (it can float in saltwater) and its ability to generate static electricity when rubbed. It should feel warm to the touch compared to glass or stone. Found commonly in the Baltic Sea region and the Dominican Republic.
