How do you test a diamond stone?
To tell if your diamond is real, place the stone in front of your mouth and, like a mirror, fog it up with your breath.
If the stone stays fogged for a few seconds, then it’s probably a fake.
A real diamond won’t fog up easily since the condensation doesn’t stick to the surface..
Will a CZ sink in water?
What do the Results Mean? Diamonds are dense and will sink quickly, while certain imitations will sink more slowly. If your gem doesn’t immediately sink to the bottom, it’s likely a glass or quartz imitation. However, other imitations, including cubic zirconia, will also sink quickly.
Do all fake diamonds float in water?
