Amber

Physical Properties

Hardness: 2.0-2.5 on Mohs scale; Color: honey-yellow, orange, or reddish-brown; Luster: Resinous; Crystal structure: Amorphous (none); Cleavage: None; Specific gravity: 1.05-1.10 (floats in saltwater).

Formation & Geological History

Formed through the fossilization of tree resin over millions of years (sedimentary environment). Most famous deposits date to the Eocene epoch (approx. 44 million years ago).

Uses & Applications

Primarily used in jewelry, decorative arts, and as a medium for scientific study (paleontology) when it contains inclusions.

Geological Facts

Amber is organic, not a true mineral. It can preserve prehistoric insects, plant matter, and even small vertebrates in incredible detail, acting as a natural time capsule.

Field Identification & Locations

Identify by its warmth to the touch (unlike cold glass/stone), its ability to float in a saturated salt solution, and it will produce a piney scent when touched with a hot needle.
