How to distinguish a pearl from a fake? How to distinguish the authenticity of pearls

1. The color of the pearl. The luster of real pearls is like a seven-color rainbow, with many colors, but not particularly bright, shining under the sun, and the transparency is better. The surface of a fake pearl is brighter and monotonous, and it doesn't look very real, with little to no transparency.

2. The feel of pearls. Real pearls have a smooth and cool feeling to the touch, while fake pearls are more noisy and warm. At the same time, you can also gently scratch your nails, and the real pearl will have a fine powder like powder falling off, but there will be no scratches.

Fake pearls will have very rotten and obvious scratches. And there is no shedding substance.

3. Friction listening method. You can rub two pearls against each other, and the sound of a real pearl will have that feeling of wind and sand, while a fake pearl will have a slippery feeling.

4. Identification method. Real pearls are generally sold at a very high price, and conversely, Yanchang is a fake pearl. So, don't buy pearls in large quantities just because they're cheap.

The imitation pearls circulating in the pearl market mainly include shell beads, plastic beads, glass beads with a layer of fish scale essence and powder pressed imitation beads on the surface. There are several ways to see it.

1. The size, color, and shape of the pearls in a string of necklaces are rarely exactly the same, while imitations are particularly uniform. So accept the imperfections of pearls.

Second, surface characteristics.

When magnified, the pearl can see a contour linear texture, which imitation pearls do not have. Pearls have a sandy feel when rubbed with teeth (not recommended) or rubbed against each other, while imitation pearls are smooth.

3. Observe through the eyelet part of the pearl.

Through the orifices, it can be observed that pearls have a concentric layered structure, which imitation pearls do not. Imitation pearl-coated beads often have a coating peeling off near the eyelets. Imitations of glass coatings can be seen with glass squares or shell-like fractures.

Fourth, the relative density.

The relative density of pearls is in; The relative density of coated plastic beads is in, and the feel is very light; Coated glass beads and powder-pressed beads are there, and the feel is heavier. (Buy a graduated cylinder another day to try this).

In addition, other methods require the use of instruments, which are not suitable for us.

The method of distinguishing the true and false pearls is as follows: first, the shape of the pearl because of its growth conditions, the shape and color of each pearl will be different, the shape of each natural pearl is different, the surface will have growth lines, and the flawless is also one in a million, you can carefully observe the appearance of each pearl, if each pearl looks exactly the same, it is very likely to be a fake pearl. Second, the color of the above mentioned natural pearls with color, especially obvious under the light source, the real pearl luster is from the inner layer of the pearl penetration, and the fake treasure of the pearl no matter what the imitation of the annihilation will only show a color, the epidermis is luminous, and very stiff and rigid, without a trace of aura.

Third, the touch of natural pearls is cool, and there is a heavy feeling in the hand, will not be hot, fake pearls have a cheap plastic feeling to the touch, there is no feeling of cold touch. Fourth, gently rub each other to rub the two pearls together, the natural pearl will rub out the pearl powder, wipe off the powder, the pearl still has a beautiful luster, and the natural pearl friction will have a frosted feeling. If it is a fake pearl, you will see peeling, rough and damaged surface, dull luster after rubbing, and the fake pearl will slip when rubbed together.

It should be noted that improper operation of this method can cause damage to the pearl, and it is not recommended to use this method for expensive pearls.
