More ABOUT PERIDOT…

Olivine is an abundant mineral, but peridot is rather rare due to its chemical instability on Earth’s surface. It’s one of the few gemstones that occur in only one colour: an olive-green.

The intensity of the green depends on the percentage of iron in the crystal structure. Rarely, peridot can have an extraterrestrial source, being contained in meteorites that have fallen to earth.

YOUR CARE GUIDE

Peridot is 6.5 to 7.0 on the Mohrs scale. It has fair to good toughness. Peridot is durable enough for jewellery wear, but should be worn with some care so as not to scratch it or subject it to hard blows that can fracture it.

Rapid or uneven heat can cause peridot to fracture. Peridot is stable to light but is easily attacked by sulphuric acid, and less easily by hydrochloric acid. 

Warm, soapy water is the best method for cleaning peridot. Ultrasonic and steam cleaners are not recommended.
