Amber / Copal

Physical Properties

Hardness: 2-2.5 on Mohs scale; Color: Yellow, honey-brown, or orange with cloudy patches; Luster: Resinous; Crystal structure: Amorphous; Cleavage: None; Specific Gravity: 1.05-1.10 (very light/buoyant)

Formation & Geological History

Formed from the fossilized resin of ancient coniferous trees (Pinus succinifera or similar species). This specimen appears to be raw, weathered amber or copal (immature amber) which likely dates from the Eocene era (~30–50 million years ago) or more recent Holocene if it is copal.

Uses & Applications

Used primarily in jewelry making, folk medicine, and decorative art. Highly valued by scientists for paleontological research when containing inclusions (insects or plant matter).

Geological Facts

Amber is one of the few organic gemstones. It is surprisingly warm to the touch compared to stone and will produce a pleasant, piney smell if touched by a hot needle. It can also generate static electricity when rubbed with a wool cloth.

Field Identification & Locations

Identify in the field by its light weight and warmth. It will float in a saturated salt bath (1/4 cup salt to 2 cups water), whereas most rocks and plastic imitations will sink. Common locations include the Baltic Sea region, Dominican Republic, and Myanmar.
