5 Methods To Identification Of Diamond

How to identify the authenticity of a diamond ring?

Diamonds are very precious high-end decorative items, and they are also necessary jewelry for marriage. However, because diamonds are expensive and rare, many fake diamonds have appeared on the market. It is imperative to identify the authenticity of a diamond ring!

So everyone must know how to identify the authenticity of a diamond ring, let's take a look.

1.Hand touch

When buying a loose diamond, you can touch the surface of the diamond with your hand to see if it is sticky. This is mainly because real diamonds have an affinity for greasy, and you will feel a sticky feeling when you touch them with your hands.

2.Sense the temperature

Diamond has the characteristics of "high thermal conductivity", so we can observe whether the diamond has a temperature. Put the diamond close to your arm or face, can you feel a little warmth? If it is a fake imitation, it will not have the heat transfer effect of a real diamond, but will be cool.

3. Exhale to distinguish authenticity

When buying diamonds, you can also breathe in the surface of the diamond and the imitation diamond at the same time. The water mist on the surface of the real diamond will evaporate faster than the water mist on the imitation diamond. Of course, this method of identification requires you to bring a diamond imitation to your peers in advance as an experimental comparison.

4.Water drop identification

Clean and wipe the diamond to make sure that there is no grease on the surface. Then, point small water droplets on the diamond. If the water droplets can stay on the diamond for a long time, then this is a real diamond. If the water droplets spread out immediately, it may be a diamond imitation.

5 .line identification

The internal refractive index of a standard cut diamond is very high, and almost no light can pass through the diamond pavilion to the table, so the bottom of the diamond is placed vertically on a piece of white paper, and the white paper is drawn with a pencil black line, passing through the table vertically You can't see the black lines. For diamond imitations with lower refractive index, such as zircon and cubic zirconia, you can see curved black lines.
