how do you find what is real diamond and what is fake?

Answer 1

To distinguish it from glass, dunk it in water. Glass will disappear. Diamond won't.

To distinguish from things like moissanite and zirconium, your jeweler will have oils with the refractive indices to make that same trick work -- the "fake" will disappear and the real diamond won't.

There are a couple of kinds of artificial diamonds made these days. In theory, the artificial diamonds will have a laser-inscribed number on them.

Answer 2

If you go to a jewelry store. They will use this gadget that will tell if it is a real diamond or not. Diamonds put off a heat that clear stones do not.
Also diamonds will have what is called an inclusion (it will look like dirt or a black spot) in them. There is no such thing as a perfect diamond.
Diamonds do cut glass but I wouldn't recommend doing it since it can break or scratch your diamond.

Answer 3

Look at it with a 10x magnifier. A real diamond will have imperfections in it that even an untrained eye will be able to see. You should see little bits of black specks, maybe tiny cracks and perhaps some "fogging" unless it's a really, really good stone. If you don't see any of these so called "inclusions", it's probably not a real diamond.

Answer 4

That is actually getting to be a problem for The Cartel. Truth be told, you cannot without destroying or near ruin of whatever shape the stone had.
It is rocks,pebbles and sand. But as humans we place value on shiny things. You cannot eat the little pebble, you cannot drink the little rock, you can scratch other sand with sand.
Pay $ to find out if you have a rock that is worth $ to another Human.
That's the way it works.

Answer 5

If you really want to know, only x-ray diffraction will tell you. American diamonds (cubic zirconia) are only slightly less hard than real diamonds and hence the glass scratch test suggested by another answerer will not work.

Answer 6

The best way to get at the truth is to take it to a jeweler for appraisal. Sometimes a jewelry store will have free appraisals clinics. Look around for one or spend the money and get it appraised. I have had one appraised and much to my surprised it was a "pretend" still was a beautiful ring and I still enjoy it

Answer 7

You'll have to go to an authority like a gemologist. Even jewelers cannot tell the difference between a diamong and a cubic zirconium sometimes.

Answer 8

Run it over glass

Real diamond will scratch it, fake won't

Answer 9

I would take this to a certifed jewler. This would be a better bet than at home tests or trying to determine the hardness.

Answer 10

throw it on the ground because supposedly diamonds are tough and hard to break, so if you do that you can solve two questions.
