Physical properties

Hardness: 2.0-2.5 on Mohs scale; Color: Yellow-orange to honey-brown; Luster: Resinous; Crystal structure: Amorphous; Specific Gravity: 1.05-1.10 (very lightweight).

Formation & geological history

Fossilized tree resin from ancient coniferous forests, primarily dating back 30 to 50 million years (Eocene epoch). It is formed through the polymerization of plant resins under high pressure and heat over geological time.

Uses & applications

Extensively used in jewelry (beads, pendants, rings), decorative arts, and historical scientific study for its ability to preserve ancient insects and plant matter.

Geological facts

Amber is one of the few organic gemstones. It is so light that it can float in saltwater. The largest deposits are found in the Baltic region, which produces nearly 90% of the world's supply.

Field identification & locations

Identify by its warmth to the touch, lightness, and ability to generate static electricity when rubbed. It can be distinguished from plastic by the 'saltwater test' (it floats in salt-saturated water but sinks in fresh water).
