Physical properties
Hardness: 2.0-2.5 on Mohs scale; Color: Brownish-red to cognac; Luster: Resinous; Crystal structure: Amorphous; Cleavage: None; Specific gravity: 1.05-1.09 (lightweight).
Formation & geological history
Formed from the fossilized resin of ancient coniferous trees, primarily from the Eocene epoch (approx. 34-56 million years ago). It is created through a process of polymerization and volatile evaporation while buried in sediment.
Uses & applications
Extensively used in jewelry (beads, pendants), as a source of succinic acid, and highly valued in paleontology for preserving biological inclusions like insects.
Geological facts
Amber is one of the few organic 'gems.' It is so light that it can float in saltwater, which is why it often washes up on Baltic shorelines after storms.
Field identification & locations
Identify by its light weight, warmth to the touch (unlike stone), and ability to generate static electricity when rubbed with cloth. It can also be verified by a saltwater buoyancy test or UV fluorescence.
