At present, in the domestic jewelry market, the average price of a carat diamond ring is about 400,000 to 300,000, while the price of those 1 carat diamond rings with very high quality and rare styles may reach 500,000 or even higher.
In the process of purchasing diamond rings, we should pay attention to the quality of diamond rings. In this regard, consumers can judge by looking at the certificate. Such as GIA certificate, national inspection certificate, etc. In addition, you can also use some simple common sense to judge, such as observation, touch, irradiation and so on.
The price of a diamond ring is calculated in carats. Generally, 0.2 carat sells for about 4000 yuan; 0.3 carat sells for about 7000 yuan, and the bigger it is, the more expensive it is. Beautiful diamonds depend on purity, whether there are cracks, how many cracks, color, cutting and so on. The price is related to the above points! Purity, luster, weight, size, color (the purer the better), exquisite workmanship, it is generally impossible to see that it is a diamond without polishing. If it is a handicraft, it depends on the brand, and it is good to have a high popularity.
IGI uses an electronic balance with an accuracy of 0.0000 1 carat to weigh the accurate weight of diamonds, and records it in the diamond appraisal report, accurate to two decimal places. So a 25 cent diamond weighs 0.25 carat. Diamonds of the same quality, the greater the weight, the more precious.
It should be pointed out that:
1. The higher the grade of the diamond, the greater the influence of the weight on the price.
2. It is especially obvious for diamonds with critical weight. Such as: 30 minutes, 40 minutes, 50 minutes, 1 carat, etc.
3. National standards less than 0.2 carats are not classified. 0.2 to 1 carat can be classified by both loose diamonds and inlaid diamonds. Diamonds larger than 1 carat must be classified in 4C detail according to the classification standard for loose diamonds.
