E.T. Phone Home . . . there’s a Gemstone from Outer Space


Peridot, the modern August birthstone and gem designated for the 16th wedding anniversary, is a beautiful, colorful, brilliant gemstone and– it’s also quite special because it is known as the “extraterrestrial gem.”

Not many people are aware that gems from outer space even exist, but tiny peridot crystals have been discovered in meteors that have fallen to earth from deep space.

Apart from the fact that it has been found in meteorites, it has also been found (in its basic form called “Olivine”) on the Moon, and rocky outcrops of the mineral were even spotted by a space craft orbiting Mars!

Apart from being a gemstone that travels in outer space, Peridot is also one of only two gems formed deep in the planet earth, in the mantle, only thrown up to the surface during volcanic eruptions or massive earth quakes.

Peridot from Earth’s own deposits was one of the first gemstones treasured by mankind and referred to as “the gem of the sun” by ancient Egyptians. Today, sources include the United States (Arizona,Texas and Hawaii), China, Myanmar (Burma) and Pakistan.

Peridot ranges in color from light yellow-green to the intense bright green of new spring grass to olive. Because of the way peridot splits and bends the rays of light passing through it, it has a velvety appearance, a rich glow, and a slightly greasy luster. The purer green a peridot is the higher the value.


Peridot’s attractive color and relatively modest price have made it popular with jewelry designers around the world.

So, if you are in possession of a Peridot gemstone, you have quite a tale to tell about where it can be found!
