How to spot a fake diamond

You can verify if the diamonds you own or you bought are real. Try these simple tests in the comforts of your home.

  1. Water Test. Fill a regular-sized drinking glass with a 3/4 full of water. Drop the loose diamond into the water, carefully. Diamonds are known to have high density. Real ones would sink to the bottom of the glass
  2. Fog Test. Breathe on to your diamond to fog it up. A real diamond conducts and dissipates heat easily. The fog will almost be gone right away if your diamond is real.
  3. Magnifying test. There are certain things to look for under a magnifying glass. First, check your diamonds for any sign of impurities. If it is flawless, it might be a fake. Real diamonds have bits of impurities inside, known as inclusions. Note that flawless diamonds are quite rare, expensive, and are usually certified.
  4. Diamond Setting. Check the setting of your jewelry as this usually gives you an indication if your diamond is real. Precious stones are usually set in gold, white gold, and platinum. Check for markings. Markings like “10k”, “14k”, “585”, “750” indicate gold setting, while “PLAT”,  “PT” “900” and “950” indicate the setting is platinum and “925” indicates Silver setting. Note, however, that modern rings and jewelries use gold and silver to set semi-precious stones.
  5. The Newspaper test. This is only applicable for loose diamonds. Get a newspaper and place the pavilion (the top part) face down. If the text is clear, then it might be an indication that your diamond is fake. Real diamonds will give a blurry text.
