Do you want to tell if your diamond is real or not without a doubt? If so, you’ve come to the right place. Whether you’re looking to sell your diamond or inspect a new stone, it’s normal to be curious about the authenticity of your jewel.
Ungenuine counterparts of the diamond include natural gems such as colorless topaz, colorless zircon and colorless sapphire. Lab-grown gemstones that closely resemble diamonds are synthetic moissanite, gadolinium gallium garnet, synthetic cubic zirconia, and yttrium aluminum garnet. Cubic zirconia is one of the most common fake diamonds, but it is less durable than real diamonds and can discolor over time.
DIAMOND AUTHENTICITY TESTS YOU CAN DO AT HOME
There’s no shortage of Internet advice on how to tell if a diamond is genuine, yet some of this information is misguided or inaccurate. Here are six surefire methods you can try at home to determine if your diamond is real:
The sandpaper test: Lay a piece of either wet or dry sandpaper on a flat surface. If your stone scratches, it’s not real. Be careful not to scratch your setting when conducting this test, as settings aren’t as hard as your stone.
The read-through test: Turn your stone upside down and place it in a newspaper. You shouldn’t be able to see any of the words through your diamond if it’s real. If it’s a diamond substitute, like cubic zirconia, you’ll be able to see the letters underneath.
The sparkles test: If you shine a light into your stone, a real diamond will reflect rainbow colors onto other surfaces while sparkling with bright white light. Those rainbow hues will appear to be inside the stone if it’s fake.
The water test: This test is simple. Drop your stone into a glass of water and observe whether it sinks or floats. A real diamond, due to its high density, will sink. A fake diamond will float to the top or middle of the glass.
The fog test: A real diamond will not fog up when you breathe onto it. Try fogging it up like you would a window or mirror for this test.
The dot test: The dot test is an excellent alternative to the read-through test. Using a pen, draw a small dot on a piece of white paper and then lay it on a flat surface. Look down onto the paper through the pointed end of the diamond. If you cannot see a reflection or the dot inside the stone, the diamond is real. If you can make out a circular reflection inside the diamond, it’s fake.
