Anyone know how to identifiy fake diamonds?

Any high maintenance female should be able to tell you in two seconds flat!

 

Into a million pieces, lol.

I had a friend bet me about this and he lost, big time. He bet me it wouldn't and he hit it with a hammer, softly too, and it turned into powder. Glass is the next hardest material, try hitting that with a hammer and let me know how hard it is...

you must have really hit it hard, and with a sledge
crushed diamond looks like little slivers, since it's crystaline density holds the molecules inline

Women are more concerned about the value than the actual appearances. Damn them to hell.

Every girl I've told about the evils of the diamond industry has said that she would prefer another stone.

Not true. Diamonds don't have plate cleaveage planes. It's not graphite.

Also, glass isn't the next hardest material to diamond. There is lots in between, like quartz.

Until they get married and notice that other stones are cheaper. After all, they have to brag about how valueable it is.

you are thinking of synthetic rubies... and they're only used in industrial applications anyway

You can try and scratch a piece of quartz with it. Quartz always scratches glass, but it will be scratched by a diamond.

You can also do the following (I remember reading this a long toime ago, so it might not be accurate...):

Make a small dot in pencil on a piece of paper. Look at the dot through the stone. A real diamond should show it correctly, but glass will show you many dots with a halo of decomposed light around them.

What are you talking about? They're used in jewelry, too.

But yes, if you want to know if it's a real diamond or not, take it to a jeweler and let them examine it. Also, IIRC, there are forms that accompany diamonds (in jewelry as well) that are used in tracking it.

Put it in a glass of water. If you can see it through the glass, you've got a fake.

alright, here's an educated response as my fiance is the manager of a jewelry store...

here are your options:
1) do it yourself. This involves either getting a magnifying glass or something that will enlarge the diamond for your view. in the center or surrounding there should be either a few to a lot of black specs depending on how nice the diamond is (if real) if no specs, then you've got a fake (too perfect)
2) take it to a jewellry store. Probably done for free, just go up to a person behind a desk (usually been there longer) and ask if it is real. My fiance can tell in a matter of seconds whether its real or fake from just eye view, but sometimes uses a microscope to show the customer the inclusions (black spots) if they want to see.


Here's hoping you got a real one.

wouldnt this have more to do with how the cut is?

This has to do with diamond being a solidified hydrogen gas. Water is two parts hydrogen, it suppose to "conceal" diamond, make it invisible.

Some man made diamonds are so good that you can not tell the difference, or rather a jeweler can not. I think the only scientific way is using something called FTIR (Fourier Transform Infrared Spectroscopy) and apparantly man made diamonds have some function group that will show up where as natural ones do not. Or maybe it was the other way around.
