Amber-gemstone

Amber is an organic gemstone,forming from  the hardened resin of ancient pine trees. the hardening process of Amber is known as polymerization,which fossilizes  the resin over many
centuries  and make it hard and sturdy.Amber is formed from viscous,sticky resin,and therefore commonly contains inclusions that got stuck in the amber and remained there when it hardened.these inclusions are usually of insects or plants,with the most well known being mosquitoes.Amber with well preserved organisms frozen internally are highly prized.
