Physical properties
Hardness 2-2.5 on Mohs scale, yellow to brown color, resinous luster, amorphous crystal structure, specific gravity 1.05-1.10.
Formation & geological history
Formed through the polymerization and fossilization of ancient tree resin, typically originating from the Eocene or Cretaceous periods.
Uses & applications
Widely used in jewelry, decorative ornaments, and for preserving ancient biological inclusions for scientific study.
Geological facts
Amber can float in salt water and often traps prehistoric insects, feathers, or air bubbles inside.
Field identification & locations
Identified by its warm touch, low specific gravity, and electrostatic properties when rubbed; found globally in regions with ancient forest deposits like the Baltic Sea.
