Physical properties
Hardness 2-2.5 on the Mohs scale, golden-brown to orange color, resinous luster, amorphous crystal structure, conchoidal fracture, and specific gravity around 1.05-1.10.
Formation & geological history
Formed from the fossilization of ancient tree resin, primarily dating from the Cretaceous to Paleogene periods (30 to 90 million years ago) in forested environments.
Uses & applications
Used extensively in jewelry, decorative carvings, and occasionally in scientific research due to trapped inclusions.
Geological facts
Amber floats in salt water and can accumulate static electricity when rubbed with cloth. It frequently preserves prehistoric insects and plant matter.
Field identification & locations
Easily identified by its low specific gravity, warm touch, and resinous odor when heated. Found worldwide, with major deposits in the Baltic region and the Dominican Republic.
