Peridot, a gem-quality variety of the mineral olivine is derived from the Arabic word for gem, or ‘faridat’. It is one of the oldest known gemstones with records dating back to 1500 B.C. Uniquely, it is one of the few gemstones available that can only be found in one color, although different shades of green can be present. Peridot is created from magma in the earth’s crust. Today the finest quality peridot can be found in Mogok in Burma although places like Pakistan, Arizona, China and Vietnam hold important deposits as well. Peridot has been found in meteors, discovered on Mars and the moon in olivine form. The Romans called it ‘evening emerald’ and within ancient Egypt it is said that Cleopatra’s famous emeralds were actually peridot gems. The 14k white gold, peridot heart ring with diamonds was originally $1,250 but is now on sale for $650.
