A diamond can be a girl’s best friend but can also be her worst enemy...that is, if the stone turns out to be fake. Whilst the only way to guarantee the authenticity of a stone is to have it appraised by an independent gemologist, knowing the warning signs of a fake is often a great indication as to whether it needs a visit to a professional.
Here are 8 ways to identify a fake diamond, providing a simple and straightforward process to help spot the warning signs:
- Check The Certification
Any genuine diamond should come complete with a certificate from a grading authority to verify its authenticity. Such a certificate should include everything which needs to be to known about the stone, including the cut, carat, clarity, colour and more.
- Check The Reflection
The reflection of a genuine diamond will have different shades of grey and white on the inside and light rainbow colours on the outside. A fake diamond will have rainbow reflections on the inside.
- Do The Fog Test
Breathe on the diamond and watch how quickly the fog clears. A genuine diamond can disperse heat rapidly and, as such, the fog should clear almost instantly. Fakes will usually take at least 2 seconds to clear.
- Check The Refractivity
The refractivity is a diamond’s ability to bend light which passes through, contributing to its brilliance, something which cannot be replicated. Place on a newspaper. With a fake, it will be possible to read the print through the diamond but not with a genuine one.
- Do The UV Test
The majority of diamonds have a light blue hue when under UV light. Test a diamond by using a UV lamp to look for this blue hue, taking note that not all diamonds will have this. As such, not all stones without this characteristic will be fake.
- Check For Imperfections
Using a loupe, check for imperfections. A fake stone will be perfect, whilst a genuine diamond will display a number of imperfections due to the fact that it came from nature. These imperfections are known as inclusions.
- Do The Sandpaper Test
Rub the diamond with sandpaper and look to identify whether it has scratched the surface. A real stone will remain perfect after being scratched given that it’s one of the world’s hardest materials yet a fake will scratch up.
- Check The Setting & Mount
A real diamond is unlikely to be set in a cheap metal and this can be one of the easiest ways to identify a fake. You would generally expect to see a diamond set in either real gold or platinum yet a fake in a cheaper, inferior metal.
