Today we’re talking about a gemstone I have come to be very fond of.
Peridot is a type of gem-quality olivine (olivine is a silicate mineral). Interestingly, peridot is one of the few gemstones which only exists in one color: olive green. The amount of iron in the gemstone determines how light or dark it can be.
It is found in lavas and xenoliths of the mantle. It can also be found in meteorites. It is not a rare gemstone, but it is rare to find peridot which is gem-quality. Peridot tends to be chemically unstable at the Earth’s surface, so it must be found at subterranean level.
We’ve seen this pair on Kate just once. I’m desperately longing to see them again, because they are one of the most striking earring sets in her collection.
From the website: “A firm Kiki favourite; these double oval stud earrings come in an array of vibrant colour combinations and are exceptionally easy and fun to wear. This pair features stunning peridot, blue topaz and diamonds set in 18ct yellow gold.”
I want to point out that Kate’s pair actually does not have the diamonds shown in the stock photo. Hers have been replaced with smaller peridot stones.
An oval peridot sits atop a slightly larger oval blue topaz stone. To fill in the gap where these two meet, there are two small peridot stones nestled in the empty space.
Kate wore them to the African Catspremiere in April 2012. They complement her Matthew Williamson dress quite nicely.
