Hardened and aged tree sap is known as amber. As trees are a part of the natural environment and sap can be sweet, this naturally attracts insects, however it is also very sticky, so as the sap continues to ooze, in can fatally trap insects and other small creatures.

Another beautiful aspect of amber is when it is polished and made into jewelry.
