I remember connecting the dots on puzzles when I was a kid. Each dot had a number and you simply drew a line from number to number (in numerical order) to create your own amazing picture. Who knew we all had such artistic talent! Of course, most of us would struggle to draw a stick person, but when we were given the dots, we became Picasso of our time. A clown face, a railroad engine, a dog, or even an intricate mountain scene was well within our grasp. I also remember a guy who told me once that if there were only two dots to connect, I could draw a stick. Now that’s funny! Just a pair-of-dots separated me from obscurity to world fame as a stick drawer! As a matter of fact, I was just asked the other day about pair-a-dot. Of course, what he was asking about was the gemstone peridot. Some folks pronounce it pair-a-dot but it is actually pair-eh-doh, and it is a fascinating gemstone.
Peridot is a very unique gemstone. First of all, peridot, the only color gemstone found in the mantle, forms in the earth along with diamond approximately 1500 miles deep. It is transported to us through a series of magma events and liquid fissures that, at any time, could destroy or alter the olivine (family name for peridot). For example, when the unstable peridot is mixed with oxygen, it sometimes reacts to the carbon dioxide and can be converted into limestone or marble. The peridot can even convert to green serpentine if the water temperature that it is traveling through is closer to normal levels. So, we have been lead to believe that peridot is common when in fact; it is extremely rare and has survived several attempts (in nature) to alter its chemical and physical makeup. Top gem peridots have been found in Arizona, China, and especially Myanmar (formerly known as Burma) and Pakistan.
As amazing as that creation is, peridot also has an extra-terrestrial component as well. Peridot has been found on Mars. In addition, a meteor has transported a unique type of peridot with inclusions. The name of this material is Pallasitic peridot. These inclusions are needle-like and usually form a 90 degree angle. However, not all Pallasitic peridot contains these needles, so the needles do not separate Pallasitic peridot from peridot from earth with every sample. There have been approximately 60 pallasite meteorites, which make up less than 1% of all meteors. This is further proof that Pallasitic peridot is very rare indeed. A small amount of separation has been achieved with the study of trace elements in the Pallasitic peridot verses peridot from earth. The Pallasitic peridot seems to have much less nickel content and lower chromium and manganese ratios as well. This is a possible separation between the two, but when dealing with levels of trace elements, it is not always an exact science.
The beauty of peridot is undeniable. It is a beautiful green to yellowish/green color that seems to glow when light is limited and bursts into Irish meadows when struck with direct light. It has even been said that you can mine peridot after dark. It is 6.5 – 7 on the Mohs hardness scale and has a good refraction measurement of 1.65 – 1.70. It is a bright and colorful gemstone that is completely natural, with no treatment used to enhance its beauty. Jewelry Television's selection of quality peridot includes peridot from earth and space. Make beautiful jewelry or simply add to your collection. You will be so glad you did. Then you too can become the Picasso of a fine gemstone collection and you don’t even have to connect a pair-of-dots! All you have to do is choose your favorie from our selection.
