There are a couple of different ways to spot a fake diamond. Typically fakes are cubic zirconia and these stones are 1) heavier than a diamond that is the same size, 2) can't be cut as sharply as a diamond, and 3) can scratch much more easily.
if you breath on a diamond and the vapor dispear right away it a true diamond if it does not then it fake
scratch the diamond against glass...if it scratches its real if it doesn't its fake
A real diamond will cut glass.
Any large diamond deserves identification by a certified gemologist, who can tell you whether or not it is fake.
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.
a real diamond can cut glass, a fake diamond cant.
A diamond, unlike a fake diamond, is extremely hard and can scratch nearly anything. A fake diamond would not be as hard. A jeweler with a microscope would also be able to determine the difference.
Take the stone to a jeweler who can use a probe to determine whether the stone is a diamond or not.
If the diamond shines too much is of a frosty color,you may consider it fake.
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..
Yes they actually have the eye scopes too to tell if its real or fake
The difference between a real diamond and a false diamond is hard to tell from appearance. But experts can determine the validity of the diamond by a magnified scope. This scope can extinguish the difference between the two by the color and density.
