Baltic amber is an oxidised resin of ancient trees that grew approximately 44 million years ago in Europe. What is now the Baltic Sea was once a wide plain with forests of conifer trees. During the Eocene Epoch more than 34 million years ago under an intensely hot climate the conifer trees exuded vast amounts of resin. The sea level slowly rose and covered the forests to form the present-day Baltic Sea. Through the millions of years of contact with air and water the tree resin oxidised resulting in the stable Baltic amber gems we know today.
