Hello, I'm a pearl producer in Zhuji. The pearl identification methods compiled before may be helpful to you.
There are many ways to identify the authenticity of pearls. After finishing, I chose six methods that are less harmful to pearls:
1, intuitive method
Intuitive method is the simplest and easiest method, which can directly observe pearls with naked eyes and distinguish them by color, shape, size and luster.
True pearls are not exactly the same in color, shape and size. Pearl is the only organic gem with vitality in the world. It is naturally formed and cannot be cast like a machine mold. Every pearl is exactly the same. If every pearl in the pearl necklace is exactly the same, there is a great possibility that it is a fake pearl. Because even if you choose real natural pearls, the size and color are uniform at most, but they will never be exactly the same, while fake pearls are the opposite. Because they are made by machines, this can be done. At the same time, if you look closely, you will find that the color of fake pearls is dead and looks dull, unlike real pearls.
2. Feeling method
Touch method, also known as feeling method, is a method to distinguish the authenticity of pearls by hand.
Real pearls will feel cool when touched by hand, while fake imitation pearls will feel greasy. At the same time, it is difficult for natural pearls to have a completely round surface. If you feel that the pearl surface is smooth and there is no dead angle, you can guess that it is a fake pearl. There is also a method of feeling, that is, to evaluate the weight of pearls by feeling, so as to infer the authenticity. Pure glass imitation pearls are heavier than natural pearls, and if they are wax-filled glass imitation pearls, their weight is only about half that of natural pearls. This method needs a solid pearl foundation.
3. Friction method
Friction method is the mutual friction between two pearls, which can be distinguished by friction phenomenon.
If real pearls rub against each other, they will have a scrawny frost feeling (rough feeling), and some powder will be lost if they are rubbed hard. Fake pearl, two beads rub against each other, which has a smooth and slippery feeling and can't rub pearl powder. Real pearls are not afraid of rubbing, because as long as the powder is wiped off after rubbing, the original luster is presented again.
4, magnifying glass observation method
Magnifier is the most effective tool to distinguish between true and false things. Observe the pearl surface with a ten-fold magnifying glass.
Real pearls can see the growth texture of natural pearls and the formation state of calcium crystals, like sand dunes blown by the wind, while the skin of fake pearls is as uneven as the surface of eggs. At the same time, we can also see that the beaded holes are extremely rough or separated by thin layers.
5. Analytical method of falling and bouncing
Because there are differences in density, weight and elasticity between natural pearls and fake pearls, the jumping height of natural pearls falling on the same article at the same height is also different.
The real pearl fell on the glass plate from a height of 60 cm, and the rebound height was about 35 cm. Under the same experimental conditions, the rebound heights of fake pearls vary greatly.
6, scraper method
Scrape the pearl surface with a knife or scissors.
Real pearls only lose some powder; Scraping on artificially coated beads will scrape out a layer of skin film, revealing the true face of glass; If you scrape on uncoated glass beads, you will only feel smooth. However, peeling the pearl surface is a very delicate work, and it can't be recovered if you are not careful! Therefore, inexperienced people should never scrape the skin of pearls with their own knives.
The above six identification methods are relatively simple and easy to master, but they will also do some harm to pearls, so be careful when identifying them.
I hope it helps you. If you have any other questions, you can consult privately.
