Peridot Gemstone Beads from Rings & Things:
Peridot beads are known by many names, including bastard emerald, chrysolite, evening emerald, hawaiite, night emerald, and peridote. These pretty green semiprecious beads are cut from an olivine variety composed of magnesium iron silicate. Peridot splits and bends the rays of light passing through it, giving it a velvety appearance and rich glow. Pronounced PEAR-ih-doh (or PEAR-ih-dot), its yellow-green color is mainly dependent on the amount of ferrous iron present. The traditional birthstone of August, peridot has been mined for over 4,000 years, and is mentioned in the Bible under the Hebrew name pitdah. It is said to have been Cleopatra's favorite gemstone. Avoid exposing peridot beads to acids, quick temperature changes, scratches, sharp blows, or home ultrasonic cleaners. Peridot is purported to help slow aging and help speech. Many believe it to increase patience, confidence, and assertiveness.
