Physical properties
Hardness: 2.0-2.5 Mohs. Color: Golden yellow to honey brown. Luster: Resinous. Crystal structure: Amorphous. Cleavage: None. Specific gravity: 1.05-1.10 (floats in salt water).
Formation & geological history
Fossilized tree resin from ancient coniferous and angiosperm trees. Baltic amber signifies ages of 35-50 million years (Eocene epoch), though some Cretaceous specimens exist.
Uses & applications
Predominantly used in jewelry, decorative ornaments, and as a medium for scientific study (paleontology/inclusions). Historically used in perfumes and folk medicine.
Geological facts
Amber is not a stone but organic fossilized resin. It often preserves ancient DNA and organisms like insects or plants in 'inclusions'. Baltic amber contains high levels of succinic acid.
Field identification & locations
Identify via the static electricity test (rubbing on wool to attract dust) or the salt water float test. Commonly found in the Baltic Sea region, Dominican Republic, and Myanmar. Real amber feels warm to the touch compared to cold glass/plastic.
