Diamond jewellery is often considered a mark of status. But sometimes you just can’t help but wonder if what was sold or gifted to you is authentic or not. Let’s say you have a necklace that was passed on to you by a relative or you purchased a ring from a sale. Wherever you acquired it from, you should always know whether or not the diamond is indeed genuine as this can significantly impact the value of the jewellery piece you own. Of course, the most ideal way to determine this is by consulting a reputable jeweler or buyer. However, if time is of the essence, here are few simple tests to determine if a diamond is real.
The read-through test
A diamond has a high level of refractivity (i.e. the ability to bend and scatter light, which causes it to sparkle). If you’re concerned that your stone might be fake, try the read-through test. Place your diamond on top of a newspaper or book, which has plenty of text. A real diamond refracts light with a high intensity making it difficult to read any text. So, if you are still able to read the lines or letters when looking through it, you might have a fake diamond in your possession.
The water test
A real diamond is high in density and will sink immediately when dropped in water. Get a glass and fill it about ¾ of the way with water and then drop the stone in it. If the diamond appears to float, it is a forgery. This test works best for loose diamond stones since the metal of a diamond jewellery piece will alter its density.
The fog test
Real diamonds don’t fog up easily. Breathe on to the stone to create some condensation. If the diamond fogs, it’s probably inauthentic.
The heat test
This method is a bit more difficult so proceed carefully. Hold the stone in a pair of metal pliers and apply heat for 30 to 60 seconds using a lighter. After this, drop the stone in in a thick rimmed glass filled with cold water. An inauthentic diamond made from cubic zirconia will crack or shatter due to the sudden change in temperature.
Check the setting
Inspect your diamond ring for any stamps or markings on the setting. While it won’t tell you for certain, it will give you a better idea. If you identify the numbers 925 engraved on the ring, it means that it’s a sterling silver setting. A real diamond will almost never be set in sterling silver because the metal is not sturdy enough. If the setting is marked with the initials C.Z., this indicates that your stone is a cubic zirconium.
Have it examined by a professional
While these tests are certainly handy, they’re not guaranteed. If you want to know for certain, get your diamond examined by a professional. An expert can assess your ring and provide accurate insights about its origin, authenticity, and value.
