How to identify genuine and fake diamonds

Diamond Identification his own at home

1.Fog test. The hands of the gems on the mouth in front, then uh breath. If mist stay longer, there are a few seconds, it probably is a fake. Really diamond heat quickly, not easily fogging. Even if you first air Oh, wait a minute and then see the diamond still is much clearer than the fake diamonds.

• Take a diamond is determined to know the true contrast is more help on the side. You can see for real diamonds from fog affected, and will be covered with fake diamond mist. If you repeat against fake diamonds air Oh, then you can see the fog is getting thicker. Every air Oh, fog fake diamond surface is more and more obvious, but real diamonds are always clear and bright.

2.Check the base and rings. Real diamonds on the cheap is unlikely to secure the base. [1] In general there will be precious metals inside the base information (10K, 14K, 18K, 585, 750, 900, 950, PT, Plat, etc.), these are relatively good. The "CZ" logo means it is not really a diamond drill. [2] This symbol represents cubic zirconia is a synthetic gemstone.

3.Check with a magnifying glass diamond jewelry. You can borrow one from a jewelry store. Natural diamonds often will have some small flaws, can be seen through a magnifying glass. Through a magnifying glass to find the flaws mineral formation, or very subtly different color, these two phenomena are really evidence of diamonds. Although diamond may not be perfect, but at least it is true.

• Cubic zirconia and laboratory synthetic diamonds (the latter is usually done by all other types of identification) have no defects. This is because the artificial diamond is synthesized in a sterile environment, rather than in the natural laboratory of nature, natural formation. Therefore, if the gem is too perfect, it is likely to be false.

• However, the real diamonds also willing to be perfect. But this is not true diamond identification standard points. Must use other methods to exclude fake diamonds say.

Identification of true and false loose diamonds at home

1.View refractive index. Refracted light is very sharp diamond bright light can go through unhindered, showing Jiaoren dazzling brilliance. The other glass or quartz material, will have less luster, because a lower refractive index of these materials. The refractive index of the stone is extremely difficult to change, even if have to re-cut professional, too, because the refractive index is one of the properties of the stone itself. Thus, by carefully examining the refractive index can be more clearly proven genuine diamonds. Here are a few methods:

• Newspapers law: diamonds upside down, on a sheet of newspaper. If you can see through the diamond newspaper text, or even if you can see the blur of black marks, then the stone is most probably false. Diamond high refractive index, so you will not see the handwriting on the newspaper through the diamond. (There are exceptions: If the cut is irregular, you may still see the word in the newspaper.)

• Blot: a pen in ink on a piece of paper to draw a point at the center of the gem ink dots. Look down the vertical dots, if the stone is not a real diamond, you will see the emergence of an annular reflection pattern on the stone. And if it is really boring, you will not see the dots through the diamond. [3] 

2.Observation of the reflected light. Real diamonds reflected light can exhibit different degrees of gray. Observation downward from the top of the diamond, if you see the rainbow colors of reflected light, then either drill Fengyun relatively low level, or it is not really boring.

• Alternatively, you can also see if there is a flash. Really boring to be lighter than the same size of glass and quartz. You can also find a piece of glass or quartz for comparison.

•  Do not confuse the flash and the reflected light. Gem cutting will affect the reflection of the strength and intensity of the light, thus affecting the intensity of the flash. Said reflected light is refracted light colors. So when viewing flash, remember to see the intensity of light, rather than color.

•  Indeed there is a stone, a light brighter than a diamond, it is moissanite, also known as Moissanite. This precious stones and diamonds extremely close, even a professional jeweler is also difficult to distinguish. Without the aid of special tools in order to distinguish between moissanite and diamonds, gems need to get in front of the eyes, with a flashlight pen light through the gem. If you can see rainbow-colored reflection, it means having birefringent properties gem is Moissanite instead of diamonds.

3.The gem lost in a glass of water, to see whether it will sink in the end section. Because of the high density, true diamond will sink, and fake diamonds tend to float, or floating at half the glasses. 

4.Heating stones will see is not broken. Heated for 30 seconds, and then thrown into a glass of cold water directly. A short period of expansion and contraction will let some fragile materials such as glass and quartz from internal split. But the real diamond then there will not be anything.
