It is a method often used by those who are more experienced to identify the true and false of the diamond by touching it by hand. Touching the crystal surface of the diamond gently with your finger will have a sticky feeling. Unique. Because diamond has an affinity for oil, and there will be a small amount of hand oil secreted on the skin of human fingers. When this skin oil contacts the crystal surface of the stone, it will feel sticky due to the affinity of diamond for oil. And those other materials will naturally not have this special feeling. However, if the discriminator has insufficient experience, it is still difficult to distinguish between genuine and fake diamonds, so this method should be used with caution. Using a pencil to identify the true or false of a diamond is a relatively simple method. This was discovered by a Soviet expert in the past. This simple method is very popular with diamond lovers. Of course, using only a pencil to identify it is definitely not absolutely reliable.
During identification, the diamond should be moistened with water first, and then lightly scratched with a pencil. On the crystal surface of a real diamond, there is no trace left by the pencil, and if it is not a diamond, it is glass , Crystal and other materials will leave traces on the surface.
