Amber

Physical Properties

Hardness: 2.0-2.5; Color: Honey-yellow, orange, or brown; Luster: Resinous; Crystal structure: Amorphous (organic); Specific gravity: 1.05-1.09.

Formation & Geological History

Fossilized tree resin from ancient forests, dating back millions of years (commonly Eocene or Cretaceous). It undergoes polymerization over millions of years under high pressure.

Uses & Applications

Used primarily in jewelry (beads, pendants), as a healing stone in alternative medicine, and for scientific research due to trapped inclusions (insects, plants).

Geological Facts

Amber is not a mineral in the strict sense but an organic gemstone. It can float in salt water and generates static electricity when rubbed with a cloth.

Field Identification & Locations

Identify by its lightweight feel, warmth to the touch (unlike cold stones), and ability to produce a pine-like scent when touched with a hot needle. Commonly found in the Baltic region and Dominican Republic.
