Many people like to wear bracelets. As the most popular accessory nowadays, the beauty of the jade bracelet combines the temperament and charm of women, letting the style bloom suddenly. Among all the jade ornaments, the jade bracelet is the most expensive. One, and the requirements for the original stone are very high. After cutting a piece of material, only when it is not a jade bracelet, will it be considered to make another jade jewelry. How to pick a good bracelet is often encountered in our collection. The problem. Like other jadeites, the first thing to pick and plant is good enough to be worth staying. Now the bracelet of a glass kind, the price of a slightly better bracelet is already very high, and it is not recommended that everyone pursue the species blindly, but The kind must be enough, the color can be very good, at the very least, the color will not change. The color is the same as the others, and the color is positive and the color is thick. But note that the side that the seller shows you is often the best side of color. At this time, turn over to see the color of the other side. Comprehensive Evaluation. Also note that you should pay attention to the color effect on the side of the circle, because what we finally see is to wear it on the hand, the external effect, that is, the color and water on the side of the circle. This is a problem we often overlook. The water and the bottom are also not much different from picking other things. Focus on cracking, we all know that crack is the most taboo of the bracelet, especially the transverse crack, is fatal, because this, at any time may cause the bracelet to break. If we break it completely, we will make a dull sound when we tap it lightly. This kind of thing can be judged as waste. But the cracking of the bracelet is often difficult to find. What do you think of this? The experience is that under strong light, the hand just blocks the bracelet and lets the light shine from the surrounding, so that the crack inside will be very clear, whether it is a crack, a crack, or a stone line. Speaking of this, some people will ask, what is the stone line? It is an internal crack of the jadeite. In the case of cracks, after the geological action of the day after tomorrow, the surface cracks grow well and the internal cracks are formed. Then the bracelet of the garden is good or the flat strip is good? Who can't decide who is good or who is bad? It can be said that each has its own advantages according to individual needs. The garden can display the water well, and it can make the color shine well, and at the same time, it is strong. However, it is rare, so in reality, we see that the high-priced bracelets are mostly gardens; but the flat strips are comfortable to wear and feel good.
