Physical properties

Hardness: 2.0-2.5 Mohs; Color: Brownish-red (Cognac/Cherry); Luster: Resinous; Crystal structure: Amorphous; Cleavage: None; Specific gravity: 1.05-1.10

Formation & geological history

Formed from the fossilized resin of ancient coniferous trees. It is not a mineral in the strictest sense as it is organic. Most commercial amber is from the Eocene epoch (34-56 million years ago).

Uses & applications

Used primarily in jewelry, lapidary arts, and as a source of succinic acid. High scientific value when containing prehistoric inclusions such as insects or plant matter.

Geological facts

Amber has the unique property of being light enough to float in saltwater. It is electrostatically charged when rubbed with a cloth, a property discovered by ancient Greeks.

Field identification & locations

Identify in the field by its light weight (much lighter than stone) and warm feel to the touch. It can be tested by its tendency to float in saturated saltwater or by a 'hot needle' test which releases a pine-like scent.
