About Amber - History and Introduction.Amber is a gemstone formed through the fossilization of tree resin. Amber resin is not the same as typical tree sap. It is sourced specifically from the Pinus succinifera tree. The fossilization of amber can be traced back to the Tertiary period, meaning that amber stones formed approximately 50 million years ago. Since amber is formed from soft and sticky resin, amber often contains animal and plant inclusions; mostly mosquitoes and other insect species. Amber that developed in coal seams is often called'resinite', and specimens sourced specifically from New Zealand coal seams are referred to as'ambrite'. Amber is one of the few varieties of organic gemstones. The word'amber' was derived from the Middle Persian word'ambar'. It was originally used to describe a hardened waxy substance found within the intestines of sperm whales called ambergris. Ambergris is used in the production of fragrances because it has a very appealing aromatic smell. During the 14th century, the use of the term amber shifted from reference to ambergris to the gemstone. Amber and ambergris were often confused with one another because both can be found washed up on beach shores. The two are easily distinguished by density. Ambergris has a much lower density and floats in freshwater. Amber gemstones do not float in freshwater, but float in saltwater. The formation process of amber begins with transformation of resin to copal.
The transformation is triggered by high temperatures and pressure of overlying resinous sediments. The exposure to heat and pressure repels terpenes, which can cause deterioration and decay. Through time and resistance, the resin eventually hardens and becomes fossilized into amber. Many trees produce resin, but most will not actually produce amber.
The tree resin must be very resilient and resistant to decay. The majority of resin deposits cannot handle prolonged exposure to sunlight, rain and extreme temperatures.
