Well, if you're not a gem expert you will not be able to tell the cut and the clarity of the stone or even if its real. You can take it to a place that sells gemstones or even a pawn shop. They can tell you with a diamond tester if it is real or not: you can't tell if its real or not by looking at the metal band.

Reputable jewelers will offer a certificate of authenticity. Quality diamonds sparkle like nothing else in the world. You can even go to someplace like Sears and have them show you the difference between a diamond and a cubic zirconium.

An x-ray crystallograph can provide a reasonably high degree of assurance when it is used to identify smaller diamonds that were cut from a larger one. A cheap way to test a questionable gem is to drop it into clear mineral oil. A real diamond will remain visible because it has an optical density that is higher than (most) fakes and higher than the oil.

The best way is to take it to a certified gemologist for an appraisal.

A Few Simple Tests:

Heft test (weight compared to size):

A diamond with the same size of a "synthetic cubic zirconia" will be lighter in weight (carat).

Hardness Test:

Diamond can scratch "synthetic cubic zirconia" easily while "synthetic cubic zirconia" can't scratch diamond. This destructive test is not recommended but if required use apply on or below girdle area of stone.

Read through effect:

RBC (round brilliant cut) diamond when placed table down on written matter (generally a line or point is enough) and viewed from above the girdle (pavilion facets) will not exhibit read through effect whereas "synthetic cubic zirconia" will exhibit low read through effect.

Inclusions:

Some diamonds will have visible inclusions whereas synthetics, especially cubic zirconia will have white unmelted powder which sometime looks like gas bubbles.

How can you tell the difference between a diamond and a fake dimand?

You can tell the difference between a diamond and a fake diamond by looking at the stone's clarity, color, cut, and carat weight. A certified gemologist can use specialized tools to measure these factors to determine if the diamond is real or fake. Additionally, examining the diamond's setting and checking for certification can also help differentiate real diamonds from fakes.


How can you tell the difference between a real diamond or a fake?

You can tell the difference between a real diamond and a fake by examining its sparkle, clarity, hardness, and weight. Real diamonds are usually clearer, harder, and heavier than fake ones, which are often less brilliant and may have imperfections. It's best to have a professional jeweler evaluate the stone if you're unsure.


How is the easiest way you can tell if a diamond is fake?

One of the easiest ways to tell if a diamond is fake is by conducting a fog test. Simply breathe on the diamond and observe how quickly it clears. A real diamond will disperse the fog quickly, while a fake diamond will hold the fog for a few seconds.


Can you tell a real diamond by breathing on it?

No, breathing on a diamond will not reveal its authenticity. The fog test, which involves breathing on a gemstone to see if it fogs up, is not a reliable method to determine if a diamond is real or fake. Other tests such as using a diamond tester or consulting a professional jeweler are more accurate ways to verify a diamond's authenticity.


How to tell if a diamond is real?

Supposedly the only way to distinguish the best manufactured white diamond from a real diamond is the fake diamonds are flawless, and no real diamond can be truly flawless. I always wondered about this though, because how hard would it be to add flaws to a fake diamond to make it appear real? So my opinon is there is no way to tell the difference between a real diamond and a fake diamond.

How do you find out if a diamond is real besides testing it with a diamond tester.?

A 'quick and dirty' test is to pass the diamond over glass. If it cuts the glass, it's probably a diamond. Some 'fake' diamonds cloud up under cold water; a real diamond remains clear. Finally, a certified gemologist will always be able to tell whether a diamond is a real diamond, or a 'fake' diamond -- using a diamond tester.
