It was the early crusaders who brought peridots into Europe during the Middle Ages, and they were very popular. Peridots have been mined for 3,500 years! Now, peridots are everywhere and they are not expensive.
The August birthstone, peridot, has yellow-green or olive green. It was added not long ago in 2016 as the August birthstone along with Sardonyx, and Spinel. Peridot symbolizes strength.
Peridot is a relatively soft stone, ranging from 6.5 to 7 on the hardness scale, making it softer than amethyst or emerald. The stone is also highly sensitive to rapid temperature changes. Because of these, we usually recommend peridot in jewelries that are not for daily use.
Where do Peridots come from ?
Beside from earth, peridots are also come from outer space. A meteorite landed in Siberia back in 1749 with peridot crystals large enough to be set into jewelry. Those mined from earth comes from China, Pakistan, and the United States.
