Amber with inclusion

Physical Properties

Hardness: 2.0-2.5 on Mohs scale; Color: honey-yellow, orange, to brown; Luster: resinous; Crystal structure: Amorphous (non-crystalline); Specific Gravity: 1.05-1.10.

Formation & Geological History

Formed from the fossilization of organic tree resin over millions of years (typically 30-90 million years old). Inclusions like insects or crustaceans occur when organisms are trapped in sticky resin which then hardens through polymerization.

Uses & Applications

Used in jewelry, decorative arts, perfume (amber oil), and high scientific value for paleontological research of prehistoric life.

Geological Facts

This specimen appears to contain a rare inclusion, possibly a small crab or arthropod. Amber is one of the few organic gemstones. It floats in saltwater, which helps in identifying authentic Baltic specimens.

Field Identification & Locations

Identify in the field by its light weight, warmth to the touch (unlike cold glass), and characteristic blue/white fluorescence under UV light. Often found in sedimentary coastal deposits.
