Additional Info

Peridot is quite an affordable gem, found naturally in yellowish-green or olive-green color. Ancient Egyptians called it "the gem of the sun". Dark olive-green gems are the most valued.

Where to buy?
For Peridot check what Amazon has to offer. You'll usually find quite a selection from many different vendors. Worth a check. For other high quality gemstones (Rubies, Saphhires, Emeralds) and especially Diamonds, I highly recommend JamesAllen.
