Amber is a natural, organic and usually transparent material with a hardness of 2 to 2.5.
In the past, this stone properties were used for medical purposes as a wound treatment.
This stone is an organic matter and in fact a kind of fossilized resin of trees, especially pine.
The process of its formation can be returned millions of years ago.
Molecular polymerization at high temperatures and pressures from high sediments converts plant gum into a kind of sap called copal or immature.
Terpenes are hydrocarbons that are produced by some plants, especially conifers, which are released at constant temperature and pressure, and thus amber.
At this time the remains of insects, animals and plants may become trapped during the formation of this stone.
The most important its mine in the world is located in Russia, east of Kaliningrad in the Baltic region.
This provides 80 to 90 percent of world amber and produces currently near 300 tons per year.
