No doubt, just like any other business there are plenty of dishonest business men who claims their product is original and authentic but it is in fact the opposite and is fake. This happens a lot in the diamond market and it is best to be well prepared and have knowledge to tell if the diamond in question is indeed a true authentic diamond. There are a few simple procedures to do to tell if your diamond is real regardless if you are a gemologist or not.
The first and easiest thing to do is what is known as the “fog” test. Unlike glass, cubic zirconium, quartz, or leaded crystal the diamond is an extremely strong and durable stone. Simply breathe onto the stone as if you were to fog up a mirror. A true diamond will not allow any condensation to stay on it as a synthetic diamond will hold the fog for a few seconds before the condensation dissipates.
Another great test but is mainly for testing loose diamonds is the written test. On a piece of paper place a dot or line a text on it, a newspapers fine print will also suffice. Place your diamond on its “table” side, the top of the diamond. With a synthetic stone, because it is so clear you will be able to read the text through all the way through it that it is acting like a magnifying glass. An authentic diamond reflects so much light that you will not be able read the text or see the dot. This is a quick, simple, and reliable test to see if your diamond is really a real diamond or not.
The obvious test to be done is the reflection test. For a real diamond, when held up to the light, in between all the facets the reflections of light will appear as shades of grey. While stones that are clear, a synthetic diamond will reflect all different colors of the rainbow indicating that it is most like a fraud.
The final test to be done which is commonly shown in the movies is taking the diamond and scratching it against glass. This is not a recommended technique to verify if your stone is authentic or not because simply if your diamond in question is indeed a fake then you will most likely damage and end up ruining the stone. None the less it is a reliable test and will easily indicate if the stone is most likely a real diamond or not.
The only way to 100% check to see if the diamond in question is real or not is to take it to a local reputable jeweler and not one that is located in a shopping mall as they may want to deceive you into selling your “fake” stone when in fact it was real.
The jeweler or diamond specialist who will check to see if your diamond is real will more often than not do this service free of charge. Jewelers have all the necessary tools and equipment to properly check and verify that the diamond is indeed real.
