Peridot is the yellowish green to greenish yellow gem variety of the mineral olivine. The word “peridot” comes from the Arabic faridat, meaning gem. This August birthstone was valued in many ancient and medieval cultures. It appeared in priests’ jewelry as early as the second century BCE and later in the chalices and churches of medieval Europe. The peridot birthstone has also been used for centuries as a protective talisman, shielding the owner from evil spirits and “terrors of the night.
”Peridot is the gem given to celebrate a 16th wedding anniversary.
Peridot, the August birthstone, has an amazing story. Although most of the peridot seen in jewelry today comes from sources such as China, Myanmar, Pakistan, Tanzania, Vietnam and the United States, some journeyed to Earth on meteorites while others are found in exotic locales like Peridot Beach, Hawaii, where the sands shimmer a luminous green.
This August birthstone has also come to Earth via pallasite (made of nickel-iron and olivine) meteorites. Thousands of meteorites have hit the earth, many of them containing olivine, but only a few have had gem-quality peridot.
With a hardness of 6.5 to 7 on the Mohs scale, cleaning peridot is a delicate process. Never use a steam or ultrasonic cleaner, as your peridot birthstone is vulnerable to thermal shock. It is safest to use a soft-bristle brush with a mild dish soap in warm water. Peridot should be stored with care to avoid scratching by gems with greater hardness.
