HOW CAN YOU TELL IF PERIDOT IS REAL?



Peridot is a beautiful gemstone, but it's also quite valuable. If you're considering buying peridot, it's important to ensure you are getting the real thing. There are a few key things to look for when determining the authenticity of peridot.



1. THE COLOR TEST


One of the easiest ways to tell if you have a genuine peridot gemstone is to examine its color. Various shades of green are available in natural peridot, but no other additional colors. A peridot gemstone with hues other than green is most likely not real. 



2. EXAMINE UNDER A LIGHT SOURCE


Natural peridot is usually bright, olive green with yellow undertones, and its color remains the same in natural or artificial light, making it unique among gems.


On the other hand, imitation jewelry consists of materials like glass, plastic, and quartz that may have slightly different tones when illuminated by various light sources.


Hold your "natural peridot" up to a lamp for the first test, and then check its color under natural light. If the stone seems lighter or darker than usual, it's probably a fake.



3. THE REFRACTION TEST


Hold your peridot gemstone against light and look into it with a magnifying glass. You should be able to see its color and internal structure.


Peridot gemstones typically have a strong birefringence or double refraction. That is, the light that enters them divides itself into two rays. If you only notice a single beam of light emanating from the gemstone, it's probably not a genuine peridot gemstone.



4. CHECK FOR INCLUSIONS


Most peridot gemstones are eye-clean, meaning they do not include any visible impurities. Peridots that are completely flawless are extremely unusual and not readily accessible. The easiest method to tell a fake from a genuine peridot gemstone is to use a jeweler's loupe to examine the stone in question. If you notice tiny cracks or other flaws on your stone, it's most likely a genuine one.



5. CHECK THE FACETS


Take a close look at the facets of the stone. If it has uneven edges, chances are it's not real peridot because peridot gemstones are pricey, so their cut is very precise. A badly-cut stone indicates that the jeweler wasn't too concerned about damaging its quality (meaning it is not a pricey stone). This is usually the case with fake peridots (which aren't, of course, rare).



6. CONSIDER THE PRICE


The most obvious difference between natural and lab-made peridot is price. The other differences--based on origin and chemistry--require a trained gemologist's or jeweler's instruments, lenses, and experienced eye to detect.


Natural peridot is more expensive than lab-made peridot. The reason is simple--natural gems are rare, and lab-made gems are not. In most cases, you'll pay about double the price for natural peridot compared to a lab-made one of similar size and quality.


Beware, if the price is too good to be true, it probably is!



7. MEASURE THE WEIGHT


You can spot a fake peridot stone if the weight is too dense. For example, CZ is very dense, from 5.5 to 5.9 times as heavy as water for equal volumes, while natural peridot weighs in at 3.4. So, a piece of jewelry with lots of small stones is likely to be CZ if it feels extra heavy.



8. USE A GEM TESTER


Use a gem tester to test your peridot. In the world of colored gemstones, current testers on the market can distinguish sapphire from tanzanite, iolite, spinel, citrine, topaz, and tourmaline; and distinguish ruby from spinel and garnet. Topaz, amethyst, and citrine are distinguishable from each other. They can also distinguish emerald stones from jadeite and garnet, topaz from aquamarine, amethyst, and citrine. Even though gem testers can't always identify the type of gemstone you have, they can reliably tell you if it is glass.



9. PURCHASE FROM A RELIABLE SOURCE


When buying peridot, it's important to purchase from a reliable source. Buying from a reputable jeweler or gem dealer will ensure that you're getting a genuine peridot gemstone. Avoid purchasing peridot from street vendors, online auction sites, or other sources where the dealers cannot guarantee the authenticity of the stone.



10. CHECK THE CERTIFCATE OF AUTHENTICITY


Any reputable brand will provide this crucial document. A certificate of authenticity will give you information on the stone, such as the quality grade, carat weight, type of gem treatment (if any), and so on. If a dealer cannot or will not provide you with a certificate of authenticity, it's best to walk away.



11. HAVE IT CHECKED BY A PROFESSIONAL GEMOLOGIST


The best way to be absolutely sure that you have a genuine peridot gemstone is to have it examined by a professional. Gemologists are trained to identify different types of gemstones and can easily tell a fake from the real thing. Gemologists use various tools to examine stones, including microscopes and ultraviolet light, and advanced equipment only available in gem labs.


If you're interested in buying peridot, it's always best to consult with a professional gemologist first. A gemologist can help you determine the quality and value of the stone before you make a purchase.
