I think it is cutting, a colorful and glittering diamond, the only thing that changes artificially is cutting. Whether a diamond is colorful and glittering, depending on whether the cutting technician and the level are superb. Otherwise, this diamond is a diamond stone. Usually, the industry is also called the second life of cutting the diamond. We are called milk diamonds and fish eye diamonds. (There is no fire color or fire color)
What is a good cut?
The international description is EX (perfect) VG (very good) GD (good) n (good) n (different) Our domestic is very good and poor. Most of the traditional gold shops are cut. The most is EX. Indeed, the cutting of VG is already very good. Perhaps it is a price relationship. Traditional gold shops are more expensive. Direct -operated companies such as Xielong Jewelry may have an advantage. The price is also true, so there are more people who choose.
What color is better?

What clarity is better?
1: Any diamond has a certain growth pattern. It only needs to be discovered under a certain multiplier magnifying glass. Generally, the personnel in the industry is also called the birthmark. As the name implies, the higher the cleanliness, the better, because the diamond is naturally formed, and there are inevitably various other growth patterns. The diamond industry stipulates that the cleanliness of a diamond is 10 times and multiple amplification mirrors. No.
2: The description of the clarity is currently the same at home and abroad. The best is that there are almost no (flawless). Later, VVS1 and 2 VS1 and 2 SI1 and 2 are currently the most selected VS1 and 2 clarity.
3: Xielong recommends that customers who are relatively high can choose diamonds above VVS's clarity F color, because the probability of natural appreciation is relatively high.

5: Buy Little carat diamond (about 02 or below below ) It is best to choose diamonds with a general net and color, because the diamond compares, a little smaller, you are a bit too luxurious if you are equipped with cutting, high color, and high profile. Suggest.
6: If the budget is not very high, I think Si is the best choice. First of all, the price of SI is more affordable. In the case of SI's clarity, the pedestrian can not be seen in the naked eye of the naked eye, and it takes 10 times the large mirror observation. It is the best policy to put the budget on cutting and size. After all, we buy diamonds to improve our own taste and show it to others. Seeing others’s diamonds must be the size, fire color and style, and we will not take it without taking it, not we will not take it, and we will not take it. For a magnifying glass to see the clarity or something, of course, the benevolent see the benevolence, the wise sees the wisdom, and buy the most important thing you like.
