Thousands of people buy diamonds every day. These stones have become the most popular choice when it comes to buying certain types of jewelry, especially those jewelry pieces used during a wedding. This would include an engagement ring, as well as wedding bands that are exchanged on the day of the wedding. Unfortunately, a lot of people who are looking to buy their very first diamond jewelry piece do not know what to look for when they are buying a diamond – or how to know if they are buying a real diamond or might be tricked into buying a fake diamond, yet expected to pay the full price. For this reason, realizing how to tell whether a diamond is real or fake is a very important factor in the buying process. Not only should people know how to check whether a diamond is real when they want to buy such a stone, but it is also important to know how to tell if a diamond is real or fake for any diamonds that a person may already own.

We are going to share multiple methods that can be utilized for this particular purpose to give you a variety of options to help you determine the authenticity of your diamond or the diamond you would like to buy.

  • diamondThe most popular test people use to test if a diamond is real is the water test. This is also probably the simplest test. Simply place the diamond carefully into a glass of water and see if the sink floats or sinks. If the stone sinks, then it is likely a real diamond.
  • Another useful test is the fog test, which includes breathing directly onto the diamond. This creates some fog on the stone. If the fog goes away quickly, then the stone may likely be a diamond. If, on the other hand, it takes too long for the fog to disappear, then there is a very good chance that the diamond being tested is fake.
  • Testing whether the stone is able to shatter is another useful way of determining if a stone is a real diamond since a diamond ranks highest on the Mohs scale of hardness. Heat the stone with a lighter and then place the stone into a glass of cold water. If it doesn’t shatter, then it is likely a real diamond.
  • The dot test has also become quite popular in recent times. Make a dot with a pen on a piece of paper and then place the diamond on top of the dot. See if you can see the dot through the diamond. If you can, then you are sitting with a fake diamond in your hands.
