Diamonds are always the best friend of women. No matter what you are, you need to be careful when buying diamonds. Recently, the new fake diamonds have come to the forefront, making people really difficult to distinguish, so today teach you how to see the move. 01. Request a valid certificate If you said nothing, please show me In the case of synthetic diamonds, the official certificate of international circulation or the certificate issued by the NGTC national inspection in China must be written with the words "synthetic diamond" or attached to the remarks column. In particular, GIA has made a certificate for natural diamonds and synthetic diamonds. The big difference is that the natural diamond certificate is printed in gold and the synthetic diamond is printed in silver. These inspection units are internationally recognized and recognized, and the consumer only needs to clearly interpret the contents of the certificate. 02, pay attention to the issuing unit It’s convincing when you are born. Buying a diamond with a certificate is not a certificate, but more importantly, it depends on the effectiveness of the certificate, whether it comes from an authoritative testing unit. The method of verifying the authority of the certificate inspection unit is very simple, as long as the website of the verification agency is judged. It is not difficult to set up a jewelry testing organization. Therefore, there are many certificates circulating in the market. The common international authority certificates are GIA, HRD, IGI, EGL and China NGTC national inspection certificate. The more impartial and authoritative the accreditation body, the more recognized the certificate. Some small accreditation agencies in the market like to print the certificate form much like these authoritative certificates. If the name is not consistent, it is best to verify it. 03, certificate secondary inspection This time must be Virgo! Certificates are usually not forged. If you are not at ease, you can log in to the website of the testing unit for certificate inquiry and related information. For example, GIA can check all the messages contained in the certificate by simply entering the certificate number. 04, carefully select the business Caution is the boat A seller with integrity will naturally not sell fakes, so try to choose a regular seller when buying. This is the fundamental guarantee to prevent the purchase of fakes, but professionalism is also important in addition to integrity. A professional business must always absorb new information, so you may wish to prepare a few questions and test them. If these are not enough, there is a higher method of identification. Magnetic identification With strong magnets, 80% of high temperature and high pressure diamonds on the market will be adsorbed. The high-temperature and high-pressure HTHP method for synthesizing diamonds by artificially simulating the environment of temperature and pressure formed by diamonds has an iron-based magnetic metal, and the magnetic metal is adsorbed by a strong magnet. Waist circumference identification The original stone of CVD synthetic diamond is polished and does not have the same natural surface as natural diamond, but the natural diamond waist has many secrets. After polishing, the residual natural surface can often be observed in the waist, so just hold a magnifying glass through The diamond waist circumference can be resolved by distinguishing the similarities and differences. Please mention the spirit of twelve points, polish your eyes, and choose the most natural diamonds~ Cashmere Turtleneck Sweater,Red Cashmere Sweater,Black Cashmere Cardigan,Black Cashmere Turtleneck Jiaxing Shenran Trading Co.,Ltd , https://www.changepose.com
