Peridot, The August Birthstone

Posted by Linda Thibodeau on

 Jewelry Tips from Lindas Jewelry Shop

      Peridot is the birthstone for August and the 16th wedding anniversary stone. Often referred to as “the protective stone," this little green gem is one of the oldest gemstones dating back to 1500 B.C. Peridot can be found in many places around the world, including meteors, Mars, and the moon.




What is Peridot?

     Peridot is a natural untreated gemstone that belongs to the Olivine group of minerals rich in iron and magnesium. The iron deposits in the stone determine the amount and intensity of green color.  Shades of color can vary from lime green, to olive green, to yellow green.

     Peridot is one of the few idiochromatic stones, meaning it only comes in one color. Many gemstones like Topaz and Garnet come in a variety of colors, and the colors are affected by trace impurities found in the stones. With Peridot, the color comes from its basic chemical composition and not any trace impurities.

Where is Peridot found?

     Peridot is a semi-precious gemstone formed deep in the earth’s mantle region. While many gemstones are formed in the Earth’s crust, Peridot stones are formed in the mantle and are brought to the earth’s surface either by tectonic shifts or volcanic eruptions. As the lava flows it carries the Peridot crystals, and as the lava cools, the volcanic ash forms into rocks with Peridot crystals inside. Peridot has also been found in meteors, and on Mars and the moon in the Olivine form.

     The largest deposits were found years ago on the volcanic island of Zabagard (St. John) in the Red Sea. Today the best quality Peridot can be found in Pakistan in the Kashmir region bordering Afghanistan, Myanmar, and Vietnam. In the US, the most prized peridot is mined in Arizona on the San Carlos reservation. These stones have a lime green color and mining is only done by Native Americans and their families. Most of our Peridot jewelry is handcrafted with stones mined in Arizona.



A Little History…

     During ancient times many believed Peridot was a protective stone, guarding those that wore it from evil spirits and night terrors. The Romans called Peridot “the evening Emerald." Today some people still believe that Cleopatra’s Emerald collection was actually Peridot. 

Caring for Peridot gemstones

     Peridot stones can be cleaned using warm water and mild soap. Gently wipe your stones using a soft cloth and be sure to rinse well to remove any soap residue. As with most gems, avoid the use of heat steamers and ultrasonic cleaners. Always remove your jewelry before showering or swimming in chlorinated pools.  When storing your gemstones, store them separately and away from other gems to avoid scratches. If possible, wrap your gems individually in a soft cloth for extra protection and place in a fabric lined jewelry box.
