Physical properties
Hardness: 2.0-2.5 on Mohs scale; Color: Yellow-orange to honey brown; Luster: Resinous; Crystal structure: Amorphous; Cleavage: None; Specific gravity: 1.05-1.10 (floats in saltwater).
Formation & geological history
Formed through the polymerization and fossilization of tree resin over millions of years (Cenozoic to Mesozoic eras). Most common specimens are from the Eocene epoch (approx. 44 million years ago).
Uses & applications
Used primarily in jewelry making, ornamental carvings, and as a valuable source of scientific information when containing inclusions (insects or plant matter).
Geological facts
Amber is not a true mineral because it is organic and lacks a crystal structure. It is famous for capturing prehistoric insects in perfect detail. If rubbed against a cloth, it can become electrostatically charged.
Field identification & locations
Identify in the field by its light weight and warmth to the touch (unlike cold stones). High-quality pieces are transparent; some can be identified by a faint pine scent when touched with a hot needle.
