Advice 1: How to identify a real diamond

All kinds of imitation and fake diamonds there are nowadays not so rare. Of course, the final conclusion about the authenticity of a diamond can be given only by a qualified technician. But if there is an urgent need to perform a preliminary study of the properties of the stone at home.
How to identify a real diamond
You will need
  • - magnifier 10-fold increase;
  • - butter;
  • - hydrochloric acid;
  • - quartz lamp;
  • - sandpaper or needle;
  • newspaper.
Instruction
1
Look closely at a piece of jewelry, in which is fixed the stone for maximum brilliance and fire a diamond, usually placed in the open frame. This mounting method also allows you to easily examine the bottom edge of the cut diamond. Mirror coating bottom faces, a sure sign of forgery.

3
Diamonds can stick to some types of fats. Test with butter: dip the stone into it and attach to the glass surface. A real diamond will stick to the glass.

5
One of the important properties of diamonds is a luminescence in ultraviolet rays. Proper lighting can be found, for example, in the disco or under a conventional quartz lamp. If under the action of ultraviolet radiation at the stone appears blue or yellow-green glow, then before you a real diamond. If the glow a different color (or completely missing), this can be a feature of this diamond, and a sign of forgery. In any case, authentication requires additional research.

  • - magnifier;
  • newspaper;
  • - sandpaper;
  • - vegetable oil;
  • glass.
Instruction
1
For a diamond often are given a colorless Topaz, lead crystal, white zircon and even ordinary glass. Don't buy a cubic Zirconia instead of diamonds? The easiest way is to hold the diamond in the palm of your hand for a few seconds. The real gems even in hot weather remain cool. If the stone is "warm" - must question its naturalness.
2
Breathe on the diamond. Transparent stones of natural origin will never misted if they are to breathe because they're having heat. Glass and zircon will instantly become fuzzy. However, this test is great for musanet – one of the high quality of "doubles" of the diamond.
3
Take a magnifying glass and carefully inspect stone for presence of natural inclusions, which are always present in these diamonds, whatever their purity. Faux stone and glass such defects have not. To see them will help only a very strong magnifier with a 20-30-fold increase.
4
Pay attention to the cut of the stone. To do this, lift its crown to the light source. All of the reflected light in this diamond have to focus in only one bright point. When viewed through a faceted diamond in the ring on your finger, then viewed through the skin is impossible.
5
Scratch the stone with sandpaper. If you remain on the surface scratches – probably before you fake. You can spend the stone on the glass. A real diamond will leave scratches on it.
6
To distinguish diamonds from pieces of glass will help an ordinary newspaper. Put a stone on it and try to see through his letters. Using a real diamond it will be impossible to see the text as it refracts the light and through the glass quite well visible even individual letters.
7
Spread diamond with vegetable oil and apply to the glass. Real stone needs to stick to it because its surface absorbs fat.
Note
These tests to determine the authenticity of the stone can only be considered additional precautions, but not the fundamental signs that you blindly and unconditionally to navigate.
