Is My Diamond Real?

Do you have a diamond that has been passed down through your family for generations, and you have no idea where it came from? Or maybe you stumbled upon a diamond-looking stone lying on the ground? If so, you may be wondering if this is a real diamond or just a fake look-a-like. There are several ways to check if the stone in your possession is the real thing or not. Who knows, you may be sitting on a precious stone!

The Diamond Water Test

This is the most straightforward test to check if your diamond is a fake quickly. Diamonds are incredibly dense objects and will always sink when dropped into water. Fill up a small bowl or glass with water. Drop the loose diamond into the water and watch what happens. If the diamond does not sink and stays close to the surface, it is fake. A real diamond will almost certainly sink directly to the bottom of the glass and not float at all. However, just because your stone sinks does not necessarily mean it is a real diamond.

Breathe Hot Air on Your Diamond

This test is slightly harder to determine the outcome. The idea is, a real diamond will not stay foggy for very long after you breathe hot air onto it. Diamonds conduct heat, which causes condensation to evaporate quickly. Fog up your diamond and watch how long it takes to clear. If the condensation lasts longer than 2 seconds, the diamond is fake.

Heat Your Diamond

It may sound insane to hold a diamond under a flame. However, if the stone is real, the flame will not harm the diamond at all. To test this, heat your diamond with a lighter for just under a minute. Then drop the diamond into cold water and watch what happens. The severe temperature change will cause a fake diamond to shatter immediately. A real diamond will not be affected at all.
