Amber, an organic gemstone, is the fossilized resin 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.
Spring green peridot is the gem variety of ovaline, a silicate mineral thought to be common in the upper mantle of Earth's crust. Peridot-grade ovaline is most abundant in Pakistan and other dry areas. Used as early as 1580 BC in Egypt, peridot is held as a symbol of the Sun.
