Although considered a gem, amber is a wholly-organic material derived from the resin of extinct species of trees. In the dense forests of the Middle Cretaceous and Tertiary periods, between 10 and 100 million years ago, these resin-bearing trees fell and were carried by rivers to coastal regions. There, the trees and their resins became covered with sediment, and over millions of years the resin hardened into amber. Headlines offers the finest quality amber. Please note that although the silver setting is as pictured, the amber may vary in color and inclusions due to the variety of characteristics of this natural resin.
