Drop the stone in a glass of water and see if it sinks to the bottom. Due to its high density, a real diamond will sink. A fake one will float at the top of the surface or in the middle of the glass.
The only real way to tell if a diamond is real is to let someone look at it that knows what they are looking at. They can tell you if it is a genuine diamond and tell you what quality it is. There are tons of imitations. There are diamond testers that pretty well for about $100.00 also. If the ring is inexpensive and the diamond looks clear not yellow with no visible imperfections, clouds, or black dots; then that sounds too good to be true. I'll attach a little more info about diamond quality as a resource.
I have a white gold and diamond ring stamped JWBR and it is definatly real.
Take your jewelery to a local jeweler who can look at it, inspect it and tell you what it is made of and the gems it contains.
No
The best way I know of is to get your diamond ring apprais3ed by a licensed jeweler who'll be able to tell you if the diamond is real or not. There's really no other way of knowing for sure since., nowadays, synthetic diamonds are made to appear really similar to natural diamonds, and there's no way of knowing if the diamond is genuine or not just by looking at it. Consult your local jeweler and see if he can appraise the diamond for you.
No. This is not Harry Potter, magic is not real.
A fake ring will have lots of color to it. You should also be able to see flaws inside a real diamond such as small air pockets. Real diamonds also have code numbers on them which only a diamond..
Show your diamond to a professional jeweler. They can usually tell you right away whether the diamond in an engagement ring is real or not. Another way to tell is to breathe hot air onto the diamond to fog it up. If the diamond holds the fog for a few seconds, it's fake. Real diamonds disperse the fog immediately. Professional testing is by thermal and electrical conductivity measurements, or by optical study of the crystals.
Take the ring to a certified gemologist for a professional inspection. They can use specialized tools to evaluate the quality and authenticity of the diamond. Additionally, you can look for a marking on the ring's band that indicates the material (e.g., "925" for sterling silver, "14K" for gold).
If the ring is stamped with RSC925, it likely means that the metal is sterling silver. To determine if the diamond is real, you can perform a few tests such as the fog test (see how quickly it clears), the newspaper test (see if you can read text through the diamond), and the water test (see if it floats in water). For a definitive answer, it's best to have the diamond evaluated by a professional jeweler.
Yes it's real
Real diamonds will cut glass, though there is speculation that some fake diamonds can cut glass, and that you can damage a real diamond by cutting glass with it. Another way to tell is to hold the diamond up in the light. If you see any orange color from the diamond, it is fake, as real diamonds have every color EXCEPT orange.
