What should I pay attention to online shopping? First, let's see if this website has ICP certificate. Generally, formal websites are prepared. It is safer to have a telecom value-added plan license. First of all, you are not afraid that they will cheat you into not giving the goods. If there is no license for telecom value-added plan, it is best to inform everyone of their contact information and ICP filing area. The best choice is that you are in the same area. In that case, you can negotiate prices and buy and sell business online. Before online shopping, you must know the 4C knowledge of diamonds, and then determine how much weight diamonds you need and the level of color clarity you have determined. Think about this, and then choose in the search. When choosing an online merchant, try to choose a store with a high credit rating, because the value of diamonds is relatively high after all, and the greater the risk, the credit guarantee is very necessary.

Netizens who choose diamond inlaid products should hope that the diamond certificate of the inlaid products comes from the national gem evaluation institution. Also pay attention to whether the embedded metal is "platinum" or "platinum". Many people think that it is 1, but it is not: "platinum" is 18K gold, which shows different colors due to different proportions of other metals, and white is one of them; "Platinum" is the name of precious metal PT, and the gold price difference between them is almost 3: 1, so the price informed by the merchant must depend on the embedded metal support.

Netizens who choose bare stones online should remember that bare stones with more than 20 points can be classified as bare stones, so it is natural to ask merchants to show their certificates. The certificate of origin should be issued by the state power giant, so as to ensure the color and purity of such diamonds. Bare stones with international certificates such as (GIA, HRD) are the best choice, because the judgment result of international certificates is the most powerful and true. However, there are also fake international certificates on the Internet, so we should also hope that the bare stone with the real GIA certificate not only has the lettering of waist line on the diamond, but also can find the corresponding judgment result on the official website of GIA.

Finally, I recommend a jewelry store with good online reputation, Jinhe Jewelry. They have their own flagship stores in Paipai and Taobao, and also have their own special B2C websites. You can go to Taobao, pat, and search Baidu.
