5 thoughts on “How can I know that I bought a real diamond ring”

Five simple methods for diamond ring identification: 1. Diamond lipophilicity: gently touching the crystal surface of a diamond with your fingers will give you a sticky feeling, which is unique to real diamonds. Because diamonds have an affinity for oil, there will be a very small amount of some secreted hand oil on the skin of human fingers. When this skin oil contacts the crystal surface of stones, it will produce a sticky feeling due to the affinity of diamonds for oil. And those other materials will naturally not have this special feeling
Second, refraction characteristics of diamonds: draw a straight line on a piece of white paper, place the diamond flat on the straight line, and observe the straight line through the diamond. If the lines at both ends of the diamond edge and the lines through the diamond are broken or deformed, it can be concluded that they are real diamonds. If the lines are still straight, they are fake diamonds
III. thermal conductivity of diamonds:
(1) put a diamond on your arm or face. If you feel it is warm, it is a fake diamond. Because real stone does not transfer heat, it should be cool no matter how you touch it
(2) breathe on the diamond. If the moisture on the diamond disappears immediately, it will prove to be a real diamond. If the water vapor stays on the diamond for a few seconds before disappearing, it is a fake diamond
IV. chemistry of diamonds: first wet the diamonds with water, and then gently cut them with a pencil. On the crystal surface of real diamonds, where the pencil cuts, there is no trace. If it is not diamonds, but glass, crystal and other materials, there will be traces on the surface
v. hardness of diamonds: in diamond ring identification, the hardness of diamonds is very strong, and it is difficult to leave scores on them with blades. In addition, a light scratch on the glass with a diamond will leave a more obvious white mark. Fake diamonds have no such phenomenon. Or rub the diamond back and forth on fine sandpaper for several times, and the one with scratches on the surface is a fake diamond, and the one without scratches is a real diamond all of the above are physical identification methods. In fact, the simplest way is to select a diamond institution of a brand to see if the diamond has a standard international certification certificate. Now, the GIA certificate is more commonly used, and it is generally difficult to fake the certificate. Therefore, it is more secure to choose a big brand Ido Chow Tai Fook and diamond fable are also well-known in China. They are all sold in shopping malls. The owners can compare them. See which one has higher cost performance
Diamond identification is still relatively difficult, especially now that synthetic diamonds are also on the market, the cost is about one third of that of natural diamonds, which is certainly not bad. As for the difference between the two, we must find an authoritative organization to identify it. At present, the most authoritative appraisal institution in China is the national gemstone quality supervision and Inspection Center (NGTC). Most of China's diamond appraisals (more than 70%) are in NGTC, and high-end diamonds are also basically appraised by NGTC. I hope it will be useful to everyone.
