Beautiful pearls can be divided into natural and artificial breeding. These two pearls are divided into: seawater pearls and freshwater pearls. The colors of the pearls are colorful, white, red, blue, yellow. Cyan, purple and black, etc.; divided into three categories in the jewelry industry, namely white pearls, black pearls, colored pearls. The so-called fake pearls refer to artificially made substitutes, such as wax-filled glass beads, solid glass beads or coated glass beads. An effective way to identify true and false pearls Intuitive method: directly observe the color, shape, size and luster of the pearl with the naked eye. If it is a real pearl, its color, shape and size are inconsistent (the true pearls that are stringed into a necklace or bracelet are selected, so the size is more uniform), while the artificial pearls are evenly sized. True pearls can show uneven rainbows, fake pearls have a single color, only one is lit, it is very glaring. Feeling method: Lightly touch the real pearl with a cool feeling; more importantly, use a right and left hand to grab a pearl to make it rub against each other. A sandy feeling (roughness) is a true pearl, and a smooth feeling is an artificial pearl. . True pearls have a falling hand, while fake pearls have no. Magnifying glass observation method: observe with 5 times or 10 times magnifying glass, the growth of the pearls (including natural beads and cultured beads) can be seen on the surface, as if the sand dunes were blown by the wind; the artificial beads can only see the eggshell Coating. Knife scraping method: using a knife or scissors to scrape on the surface of a real pearl, only some powder will fall off; while on the artificial coated bead, it will scrape a film to reveal the true face of the glass; if uncoated glass beads Scratching, only a smooth feeling.
