Physical properties
Hardness: 2.0-2.5 (Mohs scale), Color: Golden yellow to honey brown, Luster: Resinous, Crystal Structure: Amorphous (non-crystalline), Specific Gravity: 1.05-1.09
Formation & geological history
Fossilized tree resin from ancient coniferous forests. Most deposits date from the Cretaceous to the Neogene period (approx. 20 to 100 million years ago).
Uses & applications
Used primarily in jewelry, ornamental carvings, and as a scientific medium for preserving ancient insect/plant inclusions.
Geological facts
Amber is not a true mineral because it is organic and lacks a crystal structure. It is flammable and can produce static electricity when rubbed, known as the 'triboelectric effect'.
Field identification & locations
Identify by its light weight (it can float in saltwater), warm feel to the touch, and resinous smell when heated. Common in Baltic regions, Dominican Republic, and Myanmar.
