Physical properties
Hardness: 2.0-2.5 (Mohs scale); Color: Yellow, orange, honey, or reddish-brown; Luster: Resinous; Crystal structure: Amorphous; Cleavage: None; Specific Gravity: 1.05-1.09 (floats in saltwater).
Formation & geological history
Formed from the fossilization of tree resin over millions of years (Cretaceous to Eocene). It is not a mineral because it is organic and lacks a crystalline structure.
Uses & applications
Used in jewelry, decorative ornaments, perfumes (traditional), and as a valuable specimen for scientific research when it contains inclusions like insects or plants.
Geological facts
Amber is one of the few organic gemstones. Famous specimens include those found in the Baltic region and the Dominican Republic, often containing perfectly preserved prehistoric fossils.
Field identification & locations
Identify in the field by its lightweight feel and warmth to the touch. It can be tested by rubbing with a cloth to generate static electricity or by its ability to float in a saturated salt water solution.
