Some people may try selling you a faux diamond owing to simple economics. Because diamonds are so pricey, they try to pass a gemstone that resembles a diamond off as a real one. Fake or faux diamonds cost considerably less than one that is real, so the seller can earn a bigger profit by passing it off as real.
Now, reputable jewelers would not do such a thing. Some even have those who review the condition of returned products and certify diamonds. A good way to confirm authenticity is to buy certified diamonds. For instance, those who do Beverly Diamonds reviews to certify the rocks could easily tell whether these are real or not. Consider taking your gem to such professionals, but if you cannot do that, here are some tests to try.
Regardless of where you are shopping, it is always best to confirm the authenticity of the stone you are about to buy. Looking at the certificate of authenticity is one, and here are some others.
Testing a Diamond Set in a Ring
If the stone is set in an engagement ring, you will have limited options to examine its authenticity. However, you can look for some hints.
- Fog It Up: Just breathe right onto the stone. Your exhaled breath has moisture, so you should see fog or film form on it. In a diamond, that will fade away immediately. In another stone, it will be visible for many seconds before dissipating. If you continue to breathe on it, a diamond will stay clear, but other stones will get foggier.
- Stamps: Inspect any markings or stamps on the internal part of your ring. If it has the engraving “925”, this means the setting is sterling silver. Diamonds will not be set in this metal because it is too soft. If you spot a stamp that reads “CZ”, then you are looking at cubic zirconia, not a diamond.
- Setting and Mount: Inspect the setting or mount area of your ring closely. The claws in the prongs setting should be tightly fixed to the ring band and tightly wrap around your diamond, to protect the stone. Without these measures, it will become loose. A trusted jewelry retailer is not going to risk that by having it set that way with a poor quality ring mount. If the gemstone is fake, having it secured tightly in the mount is not something jewelers will strive to achieve.
Testing an Unmounted Diamond
If your gemstone is not mounted in a piece of jewelry, you can use these tests to see whether or not it is a diamond.
- The Read-Through Examination: A diamond has a high degree of refractivity, particularly as compared to another gemstone. Refractivity is the ability of the stone to bend the light and scatter it, thus creating shine.
Open a book with lots of printed text, lay your stone flat on that page and try reading it. In the event you are able to read it through the gemstone, it will most likely be a diamond replica. A diamond refracts the sunlight so strongly that one cannot see the text through it.
- Water Test: Pour water almost to the top of a tall glass, and put your stone in it. If it floats, on the top or just below the water surface, then it is no diamond. The density of diamonds is heavier than water, so these should settle right at the bottom part of the glass.
- Heat Check: Apply heat to your stone for 30 to 60 seconds, like with a lighter while holding it in pliers. Then, just drop it in a thick-walled glass containing cold water. A cubic zirconia or another fake diamond that is made from glass will shatter or crack when it is suddenly exposed to change in temperature.
Conversely, a diamond will not react when it is put under high heat or subjected to extreme changes in temperature. Do not worry, if it is a diamond, it will be completely fine. Do this test only when you do not care how it impacts the condition of your fake stone.
Fakes Are Not Always Bad
Remember, another gemstone may not be as precious as a diamond, but it is not bad to have a sparkling stone for keeps. Some people fancy the idea of buying an affordable and big gemstone that looks like a diamond as opposed to an expensive and small real one. Just confirm you know just what you are purchasing.
If your budget for a ring is limited, you can think about purchasing cubic zirconia for the time being. When you can pay for a real diamond down the road, you have the option to replace the fake stone with it.
