Every diamond, like a human fingerprint, has its own unique characteristics. 4C is a globally recognized standard for evaluating the quality of diamonds, that is, the "ID card" of each diamond, which refers to the four standards of clarity, color, carat weight and cut.
First, clarity is the standard to measure the purity and rarity of diamonds. Generally speaking, it is the purity of diamonds. The purer, the rarer. According to the characteristics observed under the magnifying glass of 10 times, the classification is carried out. If a diamond is under a magnifying glass of 10 times, no inclusions and no surface features are found, it is called flawless grade (FL), although there can be no tiny inclusions with naked eyes.
Second, the color refers to the natural tone that diamonds are born with. Most diamonds in nature are a little yellow, so the closer they are to colorless, the rarer they are. The industry standard for measuring color is to evaluate each diamond against "colorimetric stone" and then grade it with letters D (colorless) to Z (light yellow). The color grade directly affects the appearance of diamonds, but we can't blindly pursue colorless. If we don't know much about jewelry, this jewelry is not for collection. In fact, close to colorless grade is also a good choice, with higher cost performance.
3. Carat weight The weight of diamonds is generally calculated in carats, referred to as ct. Fine diamonds below 1 carat can also be expressed in minutes, that is, 30-minute diamonds and 50-minute diamonds are commonly heard. The conversion formula is: 1 carat (CT)= 0.2g = 100 minutes (Pt).
Fourthly, the first three items of cutting belong to the characteristics of diamond itself, but cutting is the only one among 4Cs that is influenced by external technology. After all, most people who buy diamonds are ordinary people, and all they buy are processed bare diamonds or finished products. Cutting directly affects the products that we can distinguish with the naked eye. For example, in the picture below, diamonds of similar size have different cutting angles, which will directly change the luster of diamonds. If the diamond is badly cut, it looks dull even if its color and clarity are high.
Merchants will talk about these four standards when introducing diamond rings. Diamonds are certified and can't be faked, so you can find a relatively satisfactory product by choosing the right style according to these standards.
As for the price, unlike gold, diamonds have an international gold price. There is no uniform standard for diamond prices, and all businesses are different. So I suggest that before buying, we can compare the prices of 2-3 brands of diamond products with the same 4C standard, and then we can know which one is cost-effective. Of course, if it is a business of the same level, the brand also affects the price. Suggestions are for reference only.
