How are peridots formed?

Along with diamonds, peridot are the only gemstones to be formed in magma in the earth's mantle, around 20 -25 miles below the surface before being pushed up by volcanic activity. It's an idiochromatic gem, which means the colour comes from the chemical composition. In this case iron is where its distinctive yellow green hue comes from and depending on the concentration of iron, an individual stone can very from yellowish green, to greenish yellow even to brownish green.

My favourite peridot fact is that peridot crystals have been found in meteorites, quite spectacularly in the Imilac meteorite, which was found in the Atacama desert in Chile and is now in the Natural History Museum, London. You can read more about this here

What kind of jewellery can be made from peridot?

Peridot measures 6.5 - 7 on the Mohs hardness scale (For reference the scale goes from 1 -10, with diamond being the hardest stone and talc being the softest) which means that it is tough enough but can be prone to scratches and knocks so does need some care and attention. It’s probably not suitable for a ring that will be worn every day, but certainly suitable for one that is to be worn on special occasions. Gems with a similar hardness are tanzanite, chrysoprase and zircon. Peridot is perfect for earrings, pendants and brooches.

Although the stone is formed in great heat and pressure, it is very sensitive to rapid temperature change, so never have your peridot jewellery steam cleaned. It is best just to wash with a soft toothbrush and mild dish soap and it can be sensitive to the acid in some people’s perspiration. It’s wise to store peridot jewellery in their own pouch or box to prevent scratches and knocks from other items.

Other peridot facts

Peridot is known as zodiac stone for Libra, some people believe that peridot is a cleansing stone, ridding the wearer of resentment, stress, anger and greed and enabling an open heart for new relationships.
