Physical properties

Hardness: 2-2.5 on the Mohs scale. Color: Yellow, orange, brown, sometimes reddish or whitish. Luster: Resinous, vitreous. Crystal structure: Amorphous (non-crystalline solid). Cleavage: None (conchoidal fracture). Specific gravity: 1.05-1.10 (floats in saltwater).

Formation & geological history

Formed from the fossilization of ancient tree resin, typically originating from coniferous trees, over millions of years (ranging from Cretaceous to Neogene periods).

Uses & applications

Used in jewelry, decorative items, scientific research (due to preserved inclusions such as insects and plant matter), and historically in folk medicine.

Geological facts

Amber can sometimes preserve delicate organisms like insects, feathers, and leaves in stunning detail, providing a window into prehistoric ecosystems.

Field identification & locations

Found worldwide, with major deposits in the Baltic region (Baltic amber), the Dominican Republic, and Myanmar. It can be identified by its warmth to the touch, resinous scent when rubbed, and low specific gravity.
