PERIDOT

Described by ancient Egyptians and the ‘gem of the sun’, Peridot is August’s birthstone and given to celebrated 16th wedding anniversaries. A member of the olivana family, the gem is a rich, golden, lime-green colour – which comes from iron –but it can also have a yellowy tinge. Pirates believed that Peridot had the power to drive away evil spirits – especially if set in gold.
