Black pearls are low-key and elegant. They are one of the most popular accessories for urban white-collar workers. Unlike the white pearls of the white enamel, the black pearls have a unique charm. The whole body exudes a rainbow luster, low-key elegance and yet a sense of style. Natural black pearls have caused the white pearls to be dyed into black pearls because of the high value. Today, we will follow the Chinese jewelry investment network Xiaobian to learn to identify natural black pearls and dyed beads.
The difference between natural black pearls and dyed beads
1, color
Black pearls have different shades of light gray to black, and its beauty lies in the color of the matching color. Turning the black pearl slowly, you can see that the slight rainbow-like flash is changing. No two pearls are exactly the same. If you see a string of (even a few) black and white uniform colors, the black pearls are faintly colored, you are almost certain that it is dyed beads, the color of the dyed beads is sluggish and drilling The black areas gathered in the hustle and bustle are deep, which is easy to observe under a ten-fold magnifying glass.
2, shape
Whether the black pearls you see are particularly round, the round black pearls are extremely rare and of high value. Typical black pearls are oblate, pear-shaped, elliptical, irregular, many with enamel or loops, so the "value-for-money black pearls" you see are fluffy and very "round". If it is, it is very likely to be dyed.
3, size
The diameter of seawater beads in China or Japan is usually no more than nine millimeters, while the diameter of black pearls is at least eight to nine millimeters, so round black pearls smaller than eight millimeters are mostly dyed beads.
4, the price
Is the black pearl you see surprisingly cheap? An eight-mm round black pearl costs more than a thousand yuan. The same size of dyed pearl is worth only one or two hundred yuan. If you are lucky enough to buy black pearls at a reasonable price, please remember to ask the merchant to indicate on the receipt. The color of the pearl is natural.
Maintenance of natural black pearls
1, not near the clear water
Do not use water to clean the Tahitian black pearl necklace. Water can enter the pores of the beads, which is not only difficult to dry, but may also ferment the inside, and the beads may turn green. If you sweat a lot when you wear it, use a soft wet towel to wipe it off carefully, then dry it and put it back in the jewelry box. After the pearl turns yellow, it can be remedy: soaking in dilute hydrochloric acid can dissolve the yellowish outer shell, so that the black pearl can reproduce the brilliant and radiant color. However, if the color turns yellow, it is difficult to reverse.
2, acid corrosion
In order to prevent the pearl's luster and color from being affected, the black pearl should be avoided from contact with acids, alkalis and chemicals such as perfume, soap, and styling water. Do not wear black pearl jewelry to swim or bathe. So please wear your lovely black pearl after makeup.
3, cashmere cloth wait
After wearing the pearls (especially on hot days), the pearls must be cleaned before they are placed, so that the luster of the black pearls can be maintained. It is best to use sheepskin or delicate flannel, do not use facial tissue, because some facial paper rubs will wear black pearls.
4, bead chain maintenance
Do not hang the bead chain for a long time, and the chain will be deformed for a long time. It is a good idea to have a long bead chain to tie the line between each bead. This practice prevents the beads from rubbing against the beads. Even if the thread is broken, you can guarantee that the beads will not be scattered around, and you will lose at most one bead.
