Let's talk about the first c (carat) carat, which refers to the weight. Needless to say, a few minutes of that kind of "diamond chip" is better than a larger unit. A diamond with a better color 1 carat, 30,000-50,000, 2 carats will cost more than 200,000. This should be related to the formation of diamonds. It is difficult to form a big one. That thing which is rare is dear. It is normal for the price difference to be large.
Let's talk about the second C (color) first. There are 23 grades of color from very white to yellow, D-Z * * *. Needless to say, the price difference of 23 grades is self-evident.
Let's talk about the third C (clarity) purity, that is to say, the number of impurities contained in diamonds is divided into six grades. Of course, the ones without impurities are the best and the most expensive. But the naked eye generally can't handle it. You need a magnifying glass.
Besides, the fourth C (cut) is also extremely important. It depends on whether the finished diamond looks dazzling or not. This is divided into five levels. The perfect tangent ratio is the best ratio of refracted light calculated according to theoretical figures. To measure, calculate and process, the natural cost will go up.
To tell the truth, many unknown small gold shops are now called gold shops, such as the supermarket outfield and the first floor of the shopping center (of course, there are also good shops on the first floor), which are called diamonds, and the prices are extremely low. What/kloc-more than 0/000 pieces of what, are all "diamond pieces" with poor color, poor cleanliness and poor cutting. The cheaper they are, the more they are. Of course, if you have the heart and the lady at the counter is patient enough, you might as well take more and choose more, or you can choose the tall one from the short ones. For example, it is obviously the same size, one is very dazzling and the other is not too dazzling. Obviously, a cutter is almost the same (you can't pick it out without a magnifying glass! )
Although diamonds are profiteering, they are really prices and products. You can buy it to trick your wife or give yourself more "jewels" (of course, it is not excluded that people with less money can have a diamond dream), and that kind of cheap diamond can still be bought. However, if you really have quality requirements, or plan to regard it as a valuable jewelry that is both beautiful and valuable, that kind of thing is not suitable.
