Physical properties

Hardness: 2.0-2.5 (Mohs scale); Color: Brownish-red to honey yellow; Luster: Resinous; Crystal structure: Amorphous; Specific gravity: 1.05-1.10 (very lightweight).

Formation & geological history

Formed through the polymerization and fossilization of tree resins from coniferous trees. This specimen likely dates from the Cretaceous to the Paleogene period (approx. 30 to 100 million years ago).

Uses & applications

Used primarily in jewelry and as ornamental objects. Highly valued for scientific study when it contains inclusions like insects or plant material.

Geological facts

Amber is a bioactive substance that can preserve delicate organic details for millions of years. It is so light that it can float in saltwater.

Field identification & locations

Look for a resinous, waxy feel and extreme lightness compared to stone. It can be identified in the field by its warmth to the touch and its ability to build a static charge when rubbed.
