In the jewelry market, dyed pearls have always been a topic of great concern. Because of the bright color and beauty of dyed pearls, they have attracted the attention of many consumers. However, the quality of dyed pearls varies, and some are even harmful to human health. Therefore, learning how to identify dyed pearls is a must-know when buying pearls.
Causes of dyed pearls
Dyed pearl refers to a treatment method that changes the original color of pearls by artificial means. Pearls are usually soaked in chemicals or applied to the surface of pearls with chemicals to increase their color depth and aesthetics.
Methods for identifying dyed pearls
1.Observe the color
Dyed pearls tend to be too uniform in color and do not have a natural transition of layering. Moreover, the color is too vivid and does not quite match the color characteristics of natural pearls. Therefore, when buying pearls, look carefully at the color and be wary of whether it is a dyed pearl if it is too uniform and too vibrant.
2.Observe the shine
Dyed pearls tend to have a brighter luster than natural pearls, but this luster is not natural enough and can sometimes even have some metallic touches. The luster of natural pearls is softer and more natural, giving a feeling of warmth. Therefore, when buying pearls, it is important to carefully observe the luster, and if you find that the luster is too bright and unnatural, you should be wary of whether it is a dyed pearl.
3.Observe the texture of the surface
Dyed pearls tend to have a smoother surface texture than natural pearls, but this smoothness is not natural and sometimes even has a greasy feel. The surface texture of natural pearls is more warm and natural, giving people a comfortable feeling. Therefore, when buying pearls, it is important to carefully observe the surface texture and be wary of whether it is a dyed pearl if it is found to be too smooth and unnatural.
4.Observe the bead holes
The bead holes of dyed pearls are usually redder than those of natural pearls because the dye penetrates into the bead holes. If you find that the color of the bead hole is unusually bright, you should be alert to whether it is a dyed pearl.
5.Tested with professional instruments
Testing with specialized instruments is the most accurate way to identify dyed pearls. By using ultraviolet fluorescence meter, X-ray fluorescence spectrometer and other instruments, it is possible to detect whether the pearl contains chemical residues, so as to determine whether it is a dyed pearl.
How to avoid buying dyed pearls
1.Choose a reputable merchant to buy pearls
When buying pearls, consumers should choose reputable merchants to buy them. These merchants generally adhere to industry norms and do not sell dyed pearls. At the same time, consumers can also choose to buy pearls with relevant certifications based on their own experience and knowledge, such as pearls certified by the "China Jewelry and Jade Quality Certification Committee".
2.Take a closer look at the characteristics of pearls
When buying pearls, consumers should carefully observe the characteristics of the pearls, such as color, luster, surface texture, bead holes, etc. If you find something abnormal, you should be wary of whether it is a dyed pearl and avoid buying a low-quality product.
3.Learn about the dangers of dyed pearls
Dyeing pearls can be harmful to human health. Therefore, consumers should be aware of the dangers of dyed pearls when buying pearls and try to avoid buying dyed products. If you find that the pearl you purchased is dyed, you should return or replace it in time.
Identifying dyed pearls is a must-know when buying pearls. Consumers should understand the causes and hazards of dyed pearls, and master some ways to identify dyed pearls.
