Amber

Physical Properties

Hardness: 2.0-2.5 Mohs scale; Color: Dark brown to golden yellow; Luster: Resinous; Crystal system: Amorphous; Transparency: Translucent to opaque; Specific gravity: 1.05-1.10.

Formation & Geological History

Formed from the fossilized resin of ancient coniferous trees. This specimen likely dates from the Cretaceous to early Paleogene periods. It undergoes polymerization over millions of years after being buried in anaerobic sediments.

Uses & Applications

Primarily used in jewelry, decorative arts, and perfume manufacturing. Historically valued for its supposed medicinal properties and fossil inclusions (insects, plant matter).

Geological Facts

Amber is not a true mineral because it is organic and has no crystalline structure. It is one of the few organic substances that can generate static electricity when rubbed, a property from which the word 'electron' is derived.

Field Identification & Locations

Identify in the field by its light weight (it can float in salt water) and warmth to the touch compared to stone. It is commonly found in the Baltic region and the Dominican Republic.
