How can you tell if a diamond is real?

Question

My mom got me a 600$ gold heart cut diamond ring from the pawn shop, and she took it to a jeweler and he said its not real, then she took it to another jeweler and he said it was real.

Is there any sure fire way to tell if a diamond is real?

Answer 1

There are some less reliable methods you can try but there are no guarantees with these:

1. The old “If it will scratch glass it has to be a diamond.” Well, it is true that diamonds do scratch glass but so do a lot of the other fakes on the market. To boot, it’s possible to injure your rock even if it’s real during your hardness test.

2. The transparency test. If you flip the diamond in question upside down and place it over some newsprint and can clearly read through the stone, it’s not a diamond. (The problem with this test is some diamonds are cut shallow and can be read through.)

3. The fog test. Put the rock in front of your mouth and fog it like you would try to fog a mirror. If it stays fogged for 2-4 seconds, it’s a fake. A real diamond disperses the heat instantaneously so by the time you look at it, it has already cleared up. (A down fall to this test is oil and dirt on the stone can effect its reliability and the test is not accurate at all on doublets where the top of the stone is diamond and the bottom is cubic zirconia epoxied together.)

4. The weight test. The most popular of diamond simulants (fake) is a cubic zirconia. C.Z.’s weigh approximately 55% more than diamonds for the same shape and dimension. So if you have a carat or gram scale at your disposal you can see if the imposter tips the scales too much.

5. The U.V. test. A high percentage of diamonds fluorescence blue when put under an ultra violet light (black light). Since 99% of all fakes don’t, a positive identification of medium to strong blue would indicate a diamond. The bad news is if this method proves you have a diamond, it also proves your diamond is worth less. Diamonds with blue fluorescence are as much as 20% less valuable. Remember, lack of blue fluorescence doesn’t mean it’s a fake; it could just be a better quality diamond.

6. Under the loop test. If you own some sort of magnifying lens, there are some things you can look for on the stone that might give away its identity:

A. Look at the rock from the top and see how well the facets (cuts on top of the diamond) are joined. They should be sharp not rolled.

B. Look at the girdle and see if it is faceted or frosty (a clear sign it’s a diamond) or waxy and slick (an indication it’s a fake).

C. While you’re looking at your stone under magnification, look into your stone to see if you detect any flaws (carbon, pinpoints, small cracks). These are typically clear indications it’s the real thing since it’s very hard to put inclusions in a fake.

D. After examining the stone, focus in on the stamps inside the setting. A stamp of "10K, 14K, 18K, 585, 750, 900, 950, PT, Plat" indicates the setting is real gold or platinum which gives a better chance that the stone in it is real as well. While you’re looking at the interior of the ring, also look for any "C.Z." stamps that would indicate the center stone is not a diamond.


Good Luck!

1) Look through magnifying glass Real diamonds are formed under the earth crust with the help of natural forces acting upon it over million of years. Due to this there are imperfections in the carbon. A real stone will be perfect - absolutely perfect. Even there are synthetic diamonds which is not identifiable. Its better to take it to an expert. 2) Sandpaper test. since diamonds are one of the world's hardest stone and it won't be scratched by the rough surface. If you scratch sandpaper to a real diamond then nothing will happen but if it's a cubic zirconium, it will scratch it up. 3)Fog Test. Breathe hot air on your diamond as you would do on a mirror. A fake diamond will fog up for a short period of time whereas a real diamond will not because it won't retain the heat

Answer 3

be careful before you try to cut glass....
...even a real one may just shatter on you from the tiny fractures that are naturally present.... then you have no diamond

taking it to jewelers may not be work though, im not really sure what the credentials are to sell jewelry are, but they may not be substantial. id either hunt down someone more reputable, or compare it side by side with another diamond of equal stature side by side under a microscope.

or you can just forget the whole matter over a small thing, consider the time and money that it is taking to determine if its real, and just say 'hey, this diamond looks really good, and even if its fake, no one can tell, not even the experts.' and then thank your mom a lot

Answer 4

Diamonds cut glass, fake ones do not.

Answer 5

diamond cut the glass but not other crystal

Answer 6

See those bubble like things on the diamond's interior? IF those are present, then it is real. If it doesn't have those bubbles, then it's fake. its artificial.

Answer 7

Look with a magnifying glass. Scratches are not there!
Glass or other imitating material can have scratches.

Answer 8

If it cuts glass, it's real; if it doesn't, it isn't.

Answer 9

you need to check 4c's of diamond
