Diamonds recruit children identify simple and practical thes

Buying diamonds, consumers are most concerned about is to buy a fake. But the professional identification of diamonds require sophisticated scientific instruments, as the general public, in the absence of scientific instruments in the case, there is no easy way to identify the authenticity of diamonds, then?
White identify the most practical method
Draw a horizontal line in the white paper, the naked face down covered in horizontal drilling, and then looking down from the back. If you see the following line through the diamond, whether straight or curved deformation of the line, the diamond is fake.
Professor dispel doubts: Because diamonds with high refractive index, the higher the refractive index, the stronger reflective power. Refractive index, the transparency will be low. Therefore, see the following horizontal lines, and certainly not diamonds.
The simplest method Kazakh gas
Kazakhstan in the diamond above the breath, it will in the surface layer of water vapor. If the water vapor quickly dispersed, diamond is real.

Professor hold off: because the diamond has high thermal conductivity, if the diamond is fake, its definitely not as good as true thermal conductivity of diamond strength. Use of diamond thermal conductivity, it was also the judge in his hands gripping the authenticity of diamonds, diamonds hot, is fake.
The most common stroke oil line
Used with oil-based pen, such as ball-point pen or gel pen with oily and so on, click in the diamond draw. The surface is left clear traces of real diamonds, if traces are small points or intermittent lines, is fake.
Professor dispel doubts: Diamond has the hydrophobic, oily face pen oil on the surface will be allowed to stay. Counterfeit goods generally do not have the characteristics of diamonds. Method has been applied to judge the authenticity of diamonds can not be too small, or no place to draw lines. Experienced people, sometimes coarse hand-measured the authenticity of diamonds, if there remain a sense, that is really the diamond, if you feel slippery, a fake, this method is the use of diamond in the pro-oil theory.

The most obvious drip method
A drop of water dripping in diamonds, water droplets if they can drum up and long-term rally to the cause, is the true diamond.
Professor dispel doubts: Diamond addition to lipophilicity, also has hydrophobic. Therefore, the drop does not occur in the diamond shall be immediately spread genuine. This method is more suitable for relatively large diamonds, so easier to observe the water droplets.
The most easy to learn fire-color observation
Get the diamond, diamonds from multiple angles, "fire color." If the changes with the viewing angle, "fire color" showing a dynamic jump, the diamond is real.
Professor clear up doubts: diamond brilliance is also called "fire-color." People like diamonds, very often because I like it very strange color. Diamond's high refractive index and high dispersion values cause the value of the diamond with this special "fire color", the most prominent of which is soft of ice blue, diamond-cut for the perfect "fire color" more prominent . Although the counterfeit goods shiny, but the gloss does not have the dynamic jump, color change or change very little basic.
