About Peridot as a Gemstone
Peridot is the gem variety of the mineral olivine, and it is idiochromatic, meaning its green comes from iron that is an essential part of its own chemistry rather than an impurity. Because of this it is always green, varying only in tone. You can read more via gemmological reference, mineral data.
Peridot forms deep in the mantle and reaches the surface in basaltic lava. It has also been recovered from certain meteorites, making it one of very few gems known to occur beyond Earth.

Frequently Asked Questions
What are the exact measurements of this Peridot?
This stone measures 13.1 x 11.2 x 6.45 mm and weighs 8.15 carats. Those figures are taken from the stone itself, not estimated from a category average.
How should this stone be set?
A bezel setting or protective prongs will help shield the girdle edges during daily wear. Your jeweller can advise on the best metal colour to complement the natural green tone.
Is the material durable enough for daily wear?
Peridot sits moderately high on the Mohs scale, meaning it withstands regular use if worn with reasonable care. Avoid exposing it to sharp impacts or hard knocks against other surfaces.
How do I clean this gemstone?
Use warm soapy water and a soft brush to remove everyday oils from the pavilion facets. Pat dry thoroughly with a lint free cloth before storing.
What distinguishes peridot from other green gems?
True peridot belongs to the olivine mineral group and possesses a notable double refraction. This optical quirk creates a subtle fuzzy appearance along the back facets when viewed closely through a loupe.
How long does delivery take, and can I return it?
We contact you directly as soon as your order is placed to arrange delivery, so you always know where the parcel is. Returns are accepted within 7 days of the date you receive the item.
Are your stones natural, or are any of them synthetic?
