Seawater pearl
First, the difference between freshwater pearls and seawater pearls
1, is there a nucleus?
Because of different culture techniques, the internal structure has also changed. The seawater pearl has a core, and the pearlite around the seawater pearl is thin. If all seawater pearls are ground, only a small amount of perlite, mostly shell powder, is not good for use or beauty. Freshwater pearls are seedless, and all the ingredients are made of mother-of-pearl, so the pearl powder made of freshwater pearls is not doped with other substances.
Step 2 output
The output of seawater pearls is very low. Generally, only three kinds of shellfish can produce a seawater pearl, while the output of freshwater pearls is relatively high. According to Yueyang, a freshwater pearl breeding base in China and even the whole world, each shellfish can produce 6-8 freshwater pearls on average, so it is conceivable that the price of seawater pearls is much higher than that of freshwater pearls.

Step 3 show up
The switch of seawater pearls is round and shiny, while the switch of freshwater pearls is oval and rice-shaped. The luster of seawater pearls is more crystal clear and radiant, while the luster of freshwater pearls is relatively lacking!
Second, the identification method of seawater pearls
1, feeling method: feeling cold, cold is true, feeling tired is false.
2. Tooth bite method: Tooth bite has no smooth feeling, which is often true with concave-convex feeling and sand feeling, while tooth bite has smooth feeling, and hard bite has some coating falling off as false.
3, intuitive method: using natural multicolored light, the shape is different for the real, the shape is mostly spherical, and the iridescence and luster are very unified for the fake.

4. Smelling method: mild heating, exhaled breath, the surface is vapor-like, mild heating has odor, and exhaled breath has water vapor.
5. Magnifying observation method: The surface is textured, and it can be seen that the generation state of calcium crystals is real, and only an eggshell-like uniform coating can fake prosperity.
6. Rebound method: drop the pearl on the glass from a height of 60 cm. The rebound height of 35 cm is true, and the rebound difference of imitation beads is false under the same conditions.
7. Polarizer observation method: Almost total light transmission or semi-light transmission is true, and the transparent layer is not a uniform round body.
Haishui pearl ornaments
As accessories, pearls can show noble status and increase personal taste. The output of seawater pearls is small and the price is expensive. In weddings, banquets, dances, speeches and other important occasions, deep-sea pearl pendant ornaments can make you more elegant. The above is the difference between freshwater pearls and seawater pearls and the identification method of seawater pearls. I hope I can help you.
