The GEM FROM HEAVEN! Extraterrestrial peridot is found only in rare pallasite meteorites.
I personally recover the peridot crystals in these 4 Billion year old iron/nickel meteorites.
Then I select the few precious crystals that are large enough and clean enough to cut a QUALITY gem.
The result is these sparkling lights from heaven!

Incredible rarity! A timeless gift from heaven.

    Extraterrestrial peridot is one of the very rarest colored gemstones in the world.   It was created at the beginning of our solar system, somewhere in outer space!   These are EXTREMELY rare and come from one of the very rarest meteorites called a pallasite. Pallasites are composed of crystals of olivine (peridot) that is encased in a matrix of nickel-iron. Peridot (pronounced pair- uh-doh) is the August birthstone. The peridot crystals were mixed in with the molten nickel-iron when two plannetoids or asteroids collided!!  Scientists say the pallasites are estimated to be in the neighborhood of 4 to 5 BILLION years old!  That's older than any gem from earth.  Between the violent formation, exploding in our atmosphere and then impacting the earth, most crystals are so fractured they crumble to pieces if removed from the iron!   That's why only a very few meteoric peridot gems have ever been cut.  
    Even more rare, is extraterrestrial cat's-eye peridot.  I found some of this extremely rare chatoyant cat's-eye meteorite peridot in August 2006, in a pallasite meteorite. An article about ET chatoyancy, showing one of my cat's-eye peridots, was published in the 2008 Summer issue of "Gems and Gemology" p. 177. A second recent article on lab identification of these crystals was published in the Fall issue, 2011.
Until meteorite hunter Steve Arnold recovered these particular pallasite meteorites and my discovery of the cat's-eye phenomenon, I do not believe any cabochon cut meteoric cat's-eye gems had ever been cut before. Ref "Gems and Gemology" Spring 1992. What made this find extraordinary is that some crystals are large enough to facet and a few have enough of the inclusions to make a chatoyant cabochon.   After cutting the first chatoyant gem, stones were were sent to GIA for research. After months of research, the GIA Lab can now positively identify "Pallasitic Peridot" that is "extraterrestrial in origin".
  Our ET gems are delivered with our signed and sealed   Certificate of Authenticity. Larger gems listed below, are delivered with their own GIA lab report, certifying extraterrestrial origin. Why guess what is authentic? When it's time to sell, hand down or appraise, jewelers and gemologists throughout the world know and trust GIA! When you want to be absolutely sure of what you are buying, a GIA cert is the world's ultimate assurance of authenticity in the gem world.

with the pallasite
The pallasite

Left pic is one of the first faceted meteoric peridot gems that I cut; it weighs approx .53 carat. Center is Rick and Steve Arnold with a large 246 pound pallasite. Steve found it, I enjoyed the once-in-a-lifetime pleasure of helping to dig it up. Being one of the first to see this 4+ BILLION year old treasure, that traveled our solar system before crashing into our tiny blue planet, was an indescribable feeling! A true gift from heaven. At right is the pallasite meteorite after being cleaned up some. The pockets of green are where some of the peridot crystals are on the surface.

Here are some things you should know about meteoric peridot faceted and cabochon gems:

   Extraterrestrial peridot contains some elements and also an inclusion that GIA identifies in order to distinguish it from the peridot found on earth. In some gems the inclusion is very slight and sometimes so abundant that it gives the gem a chatoyancy or cat's-eye effect. That is the phenomenom that I found in 2006; I cut the first known cat's-eye extraterrestrial gem. I make the cutting judgment based on this inclusion and the overall clarity of the stone; meteoric peridot is a GIA type III gem. That means that it is usually included and contains flaws and is therefore NOT downgraded because of that. I have found that most stones don't have enough of the inclusions to make a good eye, and so are faceted; that fact makes the cat's-eye gems even rarer!
  No matter whether meteoric or earthly in origin, peridot has a brittle character.  It demands respect and TLC.  While it is a suitable gem at 6.5 hardness and not overly heat sensitive, it's brittle nature needs to be recognized and respected.  Extraterrestrial peridot is so rare that it cannot easily be replaced.  For the fortunate few who will own a gem from heaven,  we suggest a protective mounting is best for this and all of your fine gems.


  The gems listed BELOW are all delivered with their own GIA Laboratory Report. What is GIA? GIA stands for the Gemological Institute of America. It is THE authority for educational, grading and analysis. A GIA certificate is recognized throughout the world by jewelers, dealers, artists, appraisers, insurance companies and professionals in the trade, and by everyone seeking concrete authenticity, based on professional laboratory analysis by experienced professional staff, as proof of gemological information and facts. Our meteoric peridot GIA laboratory reports state the weight, measurements, species, cut, color, with a conclusion that the gem is “Pallasitic Peridot that is extraterrestrial in origin and comes from a type of stony-iron meteorite known as pallasite”. Therefore, in addition to our own cert, our customers have independent verification of extraterrestrial origin. A GIA laboratory grading report is a laminated document that is a valuable asset for any gem and conclusively establishes additional important provenance of the gem.
Gems are also available that are not GIA certified, in order to keep costs down. See "Inventory" below.    NOTE: Every ET peridot gem comes with Stinson's Certificate of Authenticity. When you buy from Stinson's, you are buying from the artist who actually recovers the crystals from the solid nickel-iron meteorite and then ALSO cuts the largest crystals into the gems listed here. No one else that we know of, controls both the recovery and the creation and thus the quality! We strive to offer the very finest meteorite gems. In addition, Linda is a GIA Graduate Gemologist which is the highest title that GIA offers. She controls our standards in grading and certification, as well as helping our customers select the perfect gems for their project and budget.
