When someone walks into your shop with a diamond ring or necklace he or she is looking to appraise, you will first want to ensure that the diamond is the real deal. There are a variety of ways to check the authenticity of a diamond, many of which can be done without any major equipment. Below are four ways you can check to see if a diamond is real or fake before entering it into our online appraisal software.
- If the stone can be removed, turn it upside down on a printed piece of paper, such as a book or any document lying about. If you can read through the stone to see the text, then the diamond is most likely fake.
- Diamonds are fantastic heat conductors, and you can utilize your breath to tell if one is real or fake. When you breathe on a real diamond, the fog should disappear immediately. However, if it lingers for a few seconds, you are most likely looking at an imposter.
- Jewelers can also use a thermal conductivity probe to detect the rate at which the stone disperses heat. This test also works on most gemstones.
- You can also use a jeweler’s loupe or microscope to determine a diamond’s authenticity. Using your preferred magnification method, look at the stone through one of the bezels on the crown. If you see doubling, it is most likely synthetic moissanite.
