August Birthstone - Peridot




Peridot comes from the Arabic word "faridat" which means, "gem". In the 18th century the French were the first to call this yellowish-green stone peridot. It had been called Topaz up to that time.  As early as 1500 BC the Egyptians used peridot as a gem. It was considered the "gem of the sun".

To develop its full strength as a talisman it had to be set in gold. Legend tells us that miners searched for peridot crystals at night as moonlight made them easier to see.  They would mark the spots and come back in the daylight to dig them up.

Wearing Cautions: Peridots can abrade over time with heavy wear. Avoid wearing Peridot jewelry while using harsh chemicals.

Cleaning Cautions: Although Peridot is relatively durable, ultrasonic and steam cleaners should be used with extreme caution. If, under magnification, the stone has inclusions, revert to cleaning with a soft brush and warm, soapy water. If you opt for an unltrasonic cleaner, do not leave the Peridot in the cleaner for more than 5 to 10 minutes.
