Amber, an organic gemstone, is the fossilized sap of prehistoric trees which grew up to 50 million years ago. The stone has been used for jewelry since the time of Christ. The world's finest amber comes from the region around the Baltic sea.

Aquamarine, along with emerald, is a gemstone variety of the silicate mineral beryl. Its name meaning "sea water," aquamarine ranges in color from a sea-green to a sky-blue and generally forms large, somewhat clear crystals. In ancient times, aquamarine jewelry was thought to protect sailors.
