Xifu jewelry and diamond series mainly consists of four moves, namely, English 4C: color, cut, clarity and carat.
Know how to practice the first style: observe the color.
Color is the most important indicator of diamonds. On the international diamond value table, the price difference of each color grade is much greater than the price difference of clarity grade. GIA begins with D, and E, F, G, H, I, J...x, Y and Z represent colorless to light yellow. DE is basically colorless, with very high value, which is extremely rare in the market. FG, colorless (excellent white), is also of high value (most diamonds abroad are above this color). There are many beautiful diamonds of this grade in Xifu Jewelry. H, I, J I and J belong to white, which is basically the color of diamonds in the domestic market. As for the diamond with K color below, don't consider making a wedding ring. The color grade in international certificates is very clear, while in domestic certificates, excellent white (DEFG), white (HIJ) and light yellow white (KLMN) are used as the criteria. In addition, diamonds below 30 points generally have no international certificates, only domestic certificates.
The book of drilling knowledge second edition: mining and cutting workers
The most important thing in cutting is proportion. A good proportion can make diamonds more dazzling, so buying diamonds and cutting them depends on the proportion. The Belgian full-fire diamonds of Xifu Jewelry are perfectly cut, paying attention to perfect proportion, perfect symmetry and perfect polishing when cutting, so they consume more diamonds than standard cutting. Only 65,438+0% diamonds in the world have perfect cutting. Perfect cut's diamonds are brighter in fire, and at the same time, they will emit flashes, bright lights and firelight, so they are called "Belgian full-fire diamonds", which is the most desired gift for every lover. No matter from which angle, you can see the brightest and brightest light, and the meaning of love it reflects is unparalleled and wonderful.
The third way to know how to drill: look at the clarity.
Clarity refers to all kinds of inclusions contained in diamonds, which are divided into LC (flawless interior), VVS, VS and Si grades, and each grade is divided into small grades, such as VVS 1, VVS 2, VVS 1 and VS 2. When magnifying 10 times or more, you should be able to see the clarity. In fact, the clarity above VS (inclusive) is invisible to the naked eye, so you don't have to ask for clarity when buying diamonds.
The fourth drilling knowledge: fixed weight
The weight basically determines the value of a diamond, and the heavier it is, the more expensive it is. The unit of weight of diamonds is carats, which is the weight of a kind of beans called carats. This bean is also a cow, and each one weighs the same. One carat equals 0.2 gram. Because the unit of one carat is too big, everyone divides one carat into 100, which is why it is often said that a diamond has 30 points and 50 points. The value of diamonds is divided by weight. There is a watch for each weight range, one for the diamond seller and one for all watches. You can calculate it yourself when you buy it.
GIA (Gemological Society of America) is the most authoritative certificate about diamonds, with a score of over 30. Each GIA international certificate has a number, which lists all kinds of parameters of diamonds, including all kinds of cutting indicators given by them, such as color, clarity, symmetry, polishing degree, various proportion data and so on. And you can find this diamond on GIA's official website. The number on the international certificate corresponds to the number on the diamond. The serial number of the diamond is engraved on the waist line of the diamond, which can only be seen with a magnifying glass of 10 times. The number of GIA is GIA (hollowing out) +8 digits. The national inspection certificate has no such anti-counterfeiting means. The national inspection certificate is generally issued by eight diamond inspection institutions in Beijing, and it also has certain authority. .
When you finally grow up to be a diamond expert, you can buy a ring made of bare diamonds. It takes about 50-200 yuan to make a fancy classic, and the value of the diamond holder is generally charged by weight according to the current gold price. Xifu Jewelry provides consumers with personalized customization of loose diamonds for many years, and does not charge processing fees. Hurry up and act!
