Physical properties

Formation & geological history

Formed through the fossilization of ancient coniferous and angiosperm tree resins over millions of years (typically Cretaceous to Paleogene periods, 30-90 million years old).

Uses & applications

Used in jewelry making (beads, pendants), lapidary arts, spiritual/healing crafts, and scientific study of prehistoric inclusions.

Geological facts

Amber is an organic gemstone, not a mineral. When rubbed vigorously against wool or silk, it develops a static electrical charge, attracting light objects like dust or paper.

Field identification & locations

Identified by its lightweight feel, warmth to the touch, and distinct resinous scent when gently heated. Commonly sourced from the Baltic region, Dominican Republic, and Myanmar.
