ROCK TRIVIA: PERIDOT

Peridot was used in Egyptian jewelry from the early 2nd millennium B.C.. The stones came from a deposit on a volcanic island in the Red Sea, off the Egyptian coast. The ancient Romans also used peridot and, because the color does not change in artificial light, they nicknamed it the 'emerald of the evening'.
The peridot is one of the few gemstones which comes in only one color- the most prized is a beautiful chartreuse green color with a hint of gold. Traces of iron give the stone its color and the intensity of the color depends on the amount of iron present. The color itself can vary from shades of yellowish green and olive, and even to a brownish green. Peridot cat's eyes and star peridot are particularly rare and precious.
The most beautiful stones come from the border area between Pakistan and Afghanistan and, in the mid-1990s, a fabulous deposit of exceptional quality peridot was found in Pakistan. The find is on a mountain pass so high that the mine can only be worked in summer.
