The only people who can authenticate a real diamond are certified gemologists specializing in jewelry. However, if you are browsing rings at a flea market and want to quickly assess whether a clear stone is probably glass, cubic zirconium, quartz, or leaded crystal, there are a few easy tests you can apply without any special equipment. These tests at least rule out recognizable imposters because they rely on the way a real diamond stone refracts light, conducts heat, and looks up-close.

If the gem in question is loose and unmounted, try placing it over printing. Diamonds refract so much light that they will not work as a magnifying glass and you would see no lines, circles, or letters through them. Other clear stones like glass or crystal will reveal the print clearly. A similar test uses a small light, such as the one that comes with your key ring. If you shine the light through the stone and cannot see it on the other side, but only a bright halo around the rim, it is more likely to be a true diamond.

Diamonds are also very good at conducting heat. Breathe on the surface of the stone and immediately check to see if it has fogged up. Again, quartz, glass, and cubic zirconium will stay hazy for a moment before the condensation dissipates, but you shouldn't be able to see any moisture on a true diamond. However, one rock, called moissanite, will also pass this test, so the best way is to get a complete thermal conductivity evaluation performed by a jeweler.

Looking closely at the specks, ridges, and facets can also give you a clue into the identity of your gem. Diamonds do have inclusions, tiny bits of other minerals that got crushed into the diamond while it formed deep under the earth. However, if the facets have worn or rounded edges, bubbles, or if the gem looks rippled or pitted, it is probably glass. Those gems that are perfectly clear, with absolutely no inclusions, are probably quartz.

Hi

You want to know whether a diamond is real or fake?

1. Visit a reputed jewelry store in your area. The jewelers can test diamond and figure out how much it is worth. Jewelers have ways to test the molecular structure of a diamond and determine whether it is real diamond. Most of the jewelry store can do free of charge. Ask before store does any testing.

2. A weighing test can be used to find out the difference between fake and real diamond. For example, the weight of cubic zirconium is approximately 50% more than a real diamond of the same shape and size.

3. Fog Test. Just fog the diamond blowing air from mouth. If diamond holds the fog, then it is fake because real diamonds disperse heat quickly. This test may not be reliable due to oil layers and dirt on the diamond stone. Make sure you can clean diamond before doing this test.

4. If you put the diamond under ultra violet light, real diamond radiates blue color light. A real diamond reflects the light throughout the stone and it glitters and becomes a rainbow.

5. One of the famous known tips is to scratch glass with diamond. If glass scratches, it is real diamond.

6. Diamonds can also be tested by a hand held device known as probe which conducts heat through the stone and triggers a response, usually a beep or a flashing light. The fake diamonds actually have more color reflected, and they also have a pretty good amount of shine.

7. Most jewelers used the Mohs scale which ranks diamond. This means that sapphires, rubies and garnets are higher in ranking and hence can scratch glass too.
