How to Spot a Fake Diamond

How to Spot a
Fake Diamond
The Breath Test
Instruction:
Take the piece of diamond in your
hands and breathe into it as if you are
trying to fog your bathroom mirror.
The Breath Test
Result:
If the stone turns cloudy and retains
some of the moisture, it is most
probably fake.
The Sandpaper Test
Instruction:
Try rubbing sandpaper on the stone.
Rubbing sandpaper on the stone
shouldn’t damage it.
The Sandpaper Test
Result:
If you see a single scratch, you might
be dealing with a fake diamond (e.g.
Cubic Zirconia)
The Sparkle Test
Instruction:
Hold the diamond in the light and see
how it sparkles.
The Sparkle Test
Result:
If the inside of the stone shows
rainbow colors, you're probably
looking at a fake diamond.
Refractivity Test
Instruction:
Take your stone and put it upside
down on a piece of newspaper.
Refractivity Test
Result:
If you can see the letters through the
stone it's probably a fake one.
The Mounting Test
Instruction:
Check the stone's
mounting.
The Mounting Test
Take note:
A valuable diamond is unlikely placed
in a poor-quality metal. It is usually in
gold or platinum bands, with the karat
visible in the inner part of the metal.
Important note:
The best way to determine the
authenticity of a diamond is to bring it to
a Gemologist. Try to find one in your local
area or antique dealer, as they may have
recommendations.
