Amber

Amber is the fossil resin from a pine tree that flourished in the Baltic region some 25 to 40 million years ago. Globs of this aromatic sap poured down from prehistoric trees, often trapping insects, twigs, bark and leaves. Amber is one of the few gemstones of organic origin. It emits a sunny and bright energy capable of calming nerves and enlivening the disposition. It stimulates the intellect and helps with making choices. The ancient Greeks saw amber as hardened tears or rays of sunset. In ancient India and Egypt, amber was burned as an incense, believed to purify the surrounding area.

Amber is often confused with:
Plastic
Citrine
Chalcedony
