This aromatic resin oozed down the sides of trees, as well as filling internal fissures, trapping debris, such as seeds, leaves, feathers and insects. As geologic time progressed the forests were buried and the resin hardened into a soft, warm, golden gem, known as amber. Amber is the fossilized resin of ancient trees which forms through a natural polymerization of the original organic compounds. Most of the world&#39s amber is in the range of 30-90 million years old. Amber is known to mineralogists as succinite , from the Latin succinum , which means amber.

In most cases, the full brilliance of a gemstone can be restored simply by using a mild detergent in warm water with a soft brush (not a toothbrush). Although most commercially prepared jewellery cleaners are safe, care should be exercised when using cleaners that contain ammonia or harsh chemicals. The key area when cleaning any transparent faceted gemstone is the pavilion since this area invariably collects dirt due to the setting.
