Selection criteria of pearls:
When choosing pearls, check the luster of pearls. When pearls are placed on white soft cloth, they can see the luster similar to seven-color rainbow when facing the light, among which pearls with rich layers and strong reflective luster are of better quality.
When choosing pearls, we should also pay attention to the shape of pearls. Among natural pearls, there are few round pearls, mostly irregular round or pear-shaped. The rounder the pearls selected, the higher their value and the more valuable they are for collection.
There are few large particles in natural pearls, and their value is relatively high. Pay attention to the size of pearls when choosing them. Generally, pearls below 6 mm are not among the jewel-grade pearls, pearls of 7 ~ 9 mm are more popular, and pearls above 10 mm are more difficult to obtain.
The surface of natural pearls will not be too smooth. When selecting, you can also observe whether the surface is flawed. The fewer flaws, the higher the smoothness of pearls, and the more precious their value. Generally, no defects can be seen at a distance of 0.5 meters, and pearls are considered as standard products.
