Cleaning & Care  Warm soapy water and a soft toothbrush will help maintain the sparkle of your Peridot.

Peridot is stable to light but is easily attacked by sulphuric acid, and less easily by hydrochloric acid. It can also be attacked over a long period of time by acid perspiration. Peridot is durable enough for every day wear, but should be worn with some care as it is prone to scratches and hard knocks can fracture the stone.

Interesting Facts The Egyptians called Peridot the gem of the sun. Some believed that it protected its owner from the terrors of the night.

Peridot crystals are found in meteorites: some rare extra-terrestrial crystals are even big enough to facet as cut gemstones.

Peridot is the gem variety of the mineral olivine. Its chemical composition includes iron and magnesium.

Iron is the cause of its attractive yellowish green colours. The gem often occurs in volcanic rocks called basalts, which are rich in these two elements.

Peridots are relatively inexpensive and plentiful, and are normally available in standard shapes and sizes. The Peridot gemstone is said to represent  Love, truth, faithfulness and loyalty.
