How to use pencil to identify diamonds

People have invented and accumulated many very simple and practical methods for identifying the true and false of diamonds without instruments and distinguishing between real diamonds and synthetic diamonds, crystals, glass or zircon.

It is a method often used by more experienced people to identify the true and false of diamonds by hand. It is a sticky feeling when you gently touch the crystal face of a diamond with your fingers. This adhesiveness is a real drill. Unique. Because diamonds have an affinity for oils and fats, and there are traces of some secreted hand oil on the skin of human fingers. This skin oil will contact the crystal face of the stone, which will give a sticky feeling due to the affinity of the diamond to the oil. And those other materials naturally do not have this special feeling. However, if the discriminator's experience is not enough, it is still difficult to distinguish between true and false diamonds, so use this method with caution.

It is a relatively simple method to use pencils to identify the true and false of a diamond. This was discovered by a former Soviet expert. This simple method is very popular among ordinary diamond lovers. Of course, it is certainly not absolutely reliable to use only a pencil to identify it.

In the identification, the diamond should be wetted with water first, and then gently scribble with a pencil. On the crystal face of the real diamond, where the pencil is drawn, there is no trace, and if it is not a diamond, but a glass Materials such as crystals leave traces on the surface.

In general, pencil scribing to identify the true and false of a diamond, the accuracy of this method is higher. However, in the identification, it should be noted that some old diamond jewelry that is inlaid is not suitable for water infiltration, because if it is made of copper or silver, it is easy to oxidize. In addition, in general, the crystal face of the diamond also needs to avoid contact with oil, dust and matter.
