    Peridot – August Birthstone

    History & Folklore: The name peridot is said to have come from either the French work peritot meaning “unclear: or the Arabic word faridat meaning “gem”.  Peridot was believed by the ancients to be a gift from Mother Nature.  Archaeologists discovered ancient Egyptian jewelry from the 2nd millennium BC containing peridot.  The Romans were also fond of peridot naming it the “emerald of everything” due to its vibrant green glow.  Medieval churches in Europe have treasures and relics adorned with peridot.  Peridot is thought to bring the wearer good luck, success and peace.

    Facts & Information: Peridot is the birthstone for August and is one of the few stones that only comes in one color.  The color varies from olive, brownish green to yellow green.  Peridots with a lot of iron are the deeper green colors.  On the San Carlos Apache Indian Reservation you will fine Peridot Mesa, on of the largest producers of peridot in the world.
