Second, distinguish the quality of pearls by their shapes. Professionally speaking, shape is not a quality category, but a subjective factor, which has nothing to do with the quality of pearls. So it is not absolutely said that the quality of oval pearls is not as good as that of round pearls. But the output of pearls with different shapes is different, which is precisely the key to affect the value of pearls. A round pearl needs some cultivation control. The rounder the pearl, the higher its value. Generally speaking, the value of round pearls is 2-4 times that of non-round pearls. Round pearls cater to people's good wishes for a complete life. So we often say that the rounder the pearl, the better.
Third, distinguish the quality of pearls through the epidermis. Whether the epidermis is smooth or not and there are many defects is the key to affect the quality of pearls. The fewer flaws, the rarer the pearl, and the higher its value. I believe that everyone may have the mentality of pursuing perfection, but we must first understand that pearls are bred from pearl shells, just like children, not all of them are handsome and beautiful, and few of them are as seamless as fairies. After understanding this truth, we will know that flawless pearls are very rare. Of course, realistically speaking, flawless pearls (in the sense of the naked eye) are not without, but only belong to a very small number. So good luster, perfect roundness and perfect value are the highest. Usually, such pearls are one in a million, so these perfect pearls are generally only used as ornaments for making single or two pearls such as pearl pendants, earrings and rings, and will not be used on a string of pearl necklaces. A flawless pearl necklace can hardly reach 100% in the most critical eyes. Therefore, from an objective point of view, it is not unreasonable to pursue more perfect pearls, but it is not necessary to be too picky, so as not to affect the wearing effect and personal acceptance of defects.
Fourth, distinguish the quality of pearls by size. There is no absolute relationship between size and quality, but it is directly related to value. Just like diamonds, 30 cents and 40 cents are different in size and value. If they were a little heavier, their value would be much higher. The size of a pearl is marked by its diameter. If the difference is 0.5mm, the values will be different, such as 10- 10.5mm and10.5-11mm. The bigger the pearl, the more difficult it is to cultivate, and the less it is. So some people think why pearls are so big, but the prices are far apart. Note that you choose jewelry, not stall jewelry, any jewelry is the same. Diamonds and all kinds of precious stones are so precious. Generally speaking, for a single pendant, 9- 1 1mm is small,11-kloc-0/3mm is medium, and pearls above 13mm are large, with high value. Necklace size, 6.5-7.5mm is too small, 7.5-8.5mm is medium, 8.5-9.5mm is too big, and those above 9.5mm belong to big bead necklaces. Size is also a personal subjective factor, which is chosen according to the size, age, preference and consumption budget of the individual.
