HOw do you tell a real diamonds from a fake?

Answer 1

Well, if you scratch it on glass it might damage your diamond. I would just take it to the nearest jewellery store sometime, and ask hose people there. They can tell for you.

Answer 2

There's a good web page summarizing information about diamonds and simulants which was put together by Dr. Jill Banfield for a course titled Gems and Precious Stones at the University of Wisconsin. It's located at:

The main difference between glass and diamonds or cubic zirconia is that glass is much softer than either of these materials. Take the stone and try to cut some scrap of glass with it (like an old bottle). If it easily gouges the glass, it's either a diamond or a cubic zirconia. If it doesn't, it's glass.

Cubic zirconia is also softer than diamond so a known diamond should scratch it. You may not want to risk damaging the stone, however. Cubic zirconia also has a higher specific gravity (5.95) than does diamond (3.52) which isn't too difficult to measure if you have the equipment.

Another simple way to distinguish glass from cubic zirconia from diamond is to get a hold of a long-wave ultraviolet light (also called a black light). Diamonds will usually glow blue, cubic zirconia will glow mustard yellow, and glass will not glow at all. Read about the luminescence of various gemstones at:

Answer 3

a real diamond will scratch anything... even glass...so if say your diamond is in a ring take the ring off and find a peice of glass that isnt really in a noticable spot and try to scratch it... or take in to a jewlers and get in appraised! when they do the apprasal they usually tell you how many kt the ring or whatever it is is,and the diamond size... if they dnt just ask if they could tell u if its a real diamond.

Answer 4

seem at in below a loupe/magnifying glass. in case you spot any form of floor scratches, that's CZ. maximum jewelers could be happy to be certain the stone for you. they have a lttle hand held gadget they use too. exceptionally cool! yet another part of do is; examine the putting. real gold is marked on the interior. i.e. 14K or Platinum. greater than a number of CZ is in simple terms gold plated based metallic. If that's no longer marked that's possibly no longer diamonds.

Answer 5

Usually fakes have too much color. When fakes glimmer in the light, they have many many colors glimmering in them. Real diamonds shimmer mostly white with just a few blues, yellows, etc. But the fakes have many colors in the fire.

Answer 6

a real diamond can cut glass fake ones can't

Answer 7

cz can cut glass despite what people think about 95% of diamonds have flaws very hard to see but if you get a magnifying glass you should be able to find them another sign is the color get a cz and hold it by your diamond is your diamond a little gray in appearance compared to the cz if it is its likely a diamond h to i in color you can email or i m me for more info PLEASE DONT SCRATCH IT AS SOME PEOPLE HAVE SUGGESTED IT CAN DO DAMAGE TO THE DIAMOND DEPENDING ON THE PLANE AND CUT

Answer 10
