Peridot is the best-known birthstone for August. It is also the traditional gemstone to gift for your 16th anniversary. If you are an August baby, your birth flowers are the gladiolus and the poppy.
Historical
Peridot has been mined since around 2000BCE. The Ancient Egyptians called it the "gem of the sun" and "evening emerald". It was primarily found on the island of Topazios in the Red Sea. All gemstones mined from this island were called "topaz" due to the name.
In addition to Topazios (now called Zabargad), peridot is found all over the world. China, Pakistan, Tanzania, and Vietnam all have deposits. You can find loose crystals laying in crevices in the mountainous Kyaukpon region of Myanmar. In Arizona, there are peridot deposits across the San Carlo Apache Indian Reservation. Apache families have worked this area for generations. And Hawaii's Peridot Beach has green sand from all of the peridot!
Throughout history, peridot has been confused with other gemstones, particularly topaz and emerald. Many historians think that at least some of Cleopatra's famous emerald collection were actually peridot. The Crusaders brought back "emeralds" that were gifted to churches. Many of these were peridot as well.
Metaphysical
Peridot has traditionally been associated with light. Priests of Isis, the Egyptian goddess of rebirth & rejuvenation, crushed it into powder that they brewed into a strong drink. They would drink this before ceremonies to enhance their unity with nature.
It also has been believed to attract love and heal broken hearts. Peridot can bring good fortune and alleviate jealousy or greed. People used it to cure asthma, relieve depression, stimulate energy levels, and induce peaceful sleep. It is even said to reduce stress, sharpen the mind, and raise self-awareness.
The Hebrews were familiar with peridot. It is listed as one of the twelve gemstones in Aaron's breastplate. One of the layers in the foundation of New Jerusalem was peridot.
In Hawaii, peridot was considered to be the "tears of Pele". It was a gift from the goddess of fire, lightning, and volcanoes.
Geological
Peridot is the gem-quality variety of the mineral olivine. It varies in color from yellowish-green to greenish-yellow. The most desirable shade is a grassy green, without traces of brown or yellow. It is one of the rare gems that looks the same in sunlight, candle light, or artificial light. It has the property of double-refraction, which means that you will see its facets doubled.
Formed deeper in the earth than any other gemstone but diamond, peridot comes to the surface through volcanic and tectonic activity. It comes from the upper mantle, 20-55 miles below the surface. Almost all known peridot arose through eruptions and earthquakes. I say "almost" because occasionally it comes from outer space! Rare meteorites called pallasites contain nickel-iron and olivine. This olivine isn't usually gem-quality, but it has a much higher scientific value anyway. In 2005, the robotic space probe Stardust brought back comet dust with traces of peridot.
Until 1990, lighter shades were more plentiful in jewelry. Then a huge deposit of vibrantly colored peridot was found in the mountains of Pakistan, near the Afghanistan border. This deposit is large enough to satisfy demand for quite some time.
With a Moh's hardness of 6.5 to 7, peridot is one of the softer gemstones. It is ideal for earrings and pendants. Care should be taken with rings to prevent scratching or breaking the stone. Do not use at-home steam or ultrasonic cleaners. It seems strange for a gem that literally comes from fire, but it is heat-sensitive.You can clean it gently with a soft brush and dish detergent, or bring it to a jeweler for professional care.
