Details for August Birthstones: Peridot and Spinel



  Peridots have long been admired for their vivid green color. They can range in color from yellowish-green to brownish-green. The ancient Romans nicknamed them the "emerald of the evening" because they do not change color in artificial light.

Peridots are one of the few gemstones that can only be found in one color. The intensity of the color depends on how much iron is contained in the crystal structure. They are typically found in rocks created by volcanoes or in meteors.

Legend states that peridots could bring good luck, peace and success to the wearer. It has also been rumored that they ward off evil spirits by giving off a glow at night.

Peridots rate 6.5-7.0 on the Mohs Hardness scale which means they are susceptible to being scratched, so it is best to store them away from other jewelry. Never use ultrasonic or steam cleaners, clean your peridot jewelry with mild soap and water.



In 2016, the spinel was added as a birthstone for August. The spinel is most commonly found in red and blue. This versatile gemstone can also be found in a wide variety of other colors, such as black, violet blue, greenish blue, grayish, bright pink, pale pink, mauve, yellow, bright orange or brown.

The spinel is often assumed to be other gemstones because it tends to resemble either a ruby or sapphire. In fact, some of the most famous rubies in history have turned out to be spinel. But, its distinguishing features, like its octahedral crystal structure and single refraction are what set it apart from other gemstones.*

Spinel rate 8 on the Mohs hardness scale and are good in toughness, making it a durable gem for jewelry. Never use ultrasonic or steam cleaners, clean your spinel jewelry with mild soap and water.
