GIA certificate is the most recognized GIA certificate in the market. He has strict criteria for judging the "comprehensive quality" of diamonds. For another example, for the same budget, if you choose diamonds with GIA certificates, 4C may not be high. At this time, I often hear the clerk say, "Why don't you drop the certificate?"? Because you have lowered your certificate and become another certificate, there are more diamonds for you to choose from. Of course, the quality of diamonds at this time is not as good as GIA. Therefore, the voucher for buying a good diamond cannot be exchanged.
Fluorescence is not the 4C standard, but it is the main factor that affects the price of diamonds. Fluorescence is a double-edged sword. It is not recommended to buy diamonds with fluorescence above G color, which will affect the fire color of diamonds. However, if the color is below G color, especially I-J color, we suggest buying weak or medium fluorescent ones instead. At this time, fluorescence will play a positive role, which will improve the color of the diamond and will not appear so yellow. The blue flame of Titanic's Ocean Star and psychic jewelry are both fluorescent, so it depends on the color you choose.
The 4C grading of diamonds "4C" standard can measure the value and quality of a diamond, and it is also a general evaluation standard. The so-called "4C" refers to the carat weight, clarity, color and cut of a diamond.
Price formula: diamond price = weight+color+clarity+cut.
The main reason of budget is budget, and the amount of budget can determine what kind of ring you choose. I believe you don't know much about the quality of some parameters of diamond ring, and sometimes you may feel embarrassed to say the budget. But if you tell the consultant the budget, the consultant will introduce it to you according to her professional level. If you are really embarrassed, you can look at the approximate price online first, so that you have a general budget range.

The size of a diamond can be determined by the total budget. There was an article about diamond ring 4C before. Friends who haven't seen it can open it. Diamonds come in two sizes:
(1) Collection: If it is necessary to collect, it is generally more than one carat (provided that the 4C level is high), and the bigger the better.
(2) Wear it at ordinary times (get married): If this is the demand, you can choose to wear it below 50 points, which is a hat that you usually wear. Usually you will choose to leave at the age of 30.
