The real pearl surface has a special luster, soft and restrained; The surface of a real pearl is not completely smooth when you look at it carefully, because the pearl is wrapped layer by layer in the process of formation, and there will be extremely tiny pores on the surface; Real pearls are the product of shellfish metabolism, and there can be no completely flawless pearls. Good pearls are almost invisible to the naked eye, but there must be; As mentioned above, the rounder a pearl is, the rarer it is, but when it is completely round, you think it is unnatural and generally not true.

Identification method:

1. Observation: From the aspects of shape, flaw and luster (skin luster), the real pearl luster is moist, and the surface luster will change at different angles, which is called rainbow color. Most fake pearls are coated with a layer of pearl powder on a glass core or a plastic core, which is essentially different from the luster of real pearls. This means that "fake pearls are mostly' dead colors'".

2. Touch, touch: Real pearls feel cold and moist, with a sense of life, a sense of falling, and moderate weight, especially beads. False beads will be overheated, overweight or underweight;

3. Friction: Use jewelry cloth or two beads to gently rub each other, the real pearls will have obvious roughness, and the fake beads will be very smooth;

4. Magnifier: Observing the pearl surface, the pores of the real pearl are evenly distributed, and there are visible natural defects under the magnifying glass of 10 times. Fake pearls are almost tender enough to see artificial traces under a magnifying glass, or smooth without traces, or with painting traces, which are easy to identify;

5.x-ray: It is very obvious that almost all kinds of real pearls will emit different fluorescent colors under different wavelengths of purple and infrared radiation, while fake pearls, even pearls made of perlite, do not have this characteristic.

6. Look at the certificate: regular jewelry sales have national inspection or provincial inspection certificates, which are the most reliable.

As for the pendant chain, it depends on what pearls you match. Generally, freshwater pearls are matched with 925 silver, and good ones may also be matched with K gold, but freshwater pearls are mostly white or pink, so generally, silver chains look good; Seawater pearls are generally gold pearls, gold 18K gold, and black pearls are white 18K gold.
