Generally, pearl jewelry do not need to change color, only black pearl production because of less expensive, so only light-colored pearls for dealing with change color to become dark. Color change the current method of staining and release
Shooting of two types of radiation.
1, staining Pearl
Qian Yanse pearls jewelry will be put into nitric acid and ammonia in water, and then removed by sunlight or hydrogen sulfide gas smoke, so that we can become a black ash.
2, exposure to pearl color
Light-colored pearls through the r-ray irradiation can wink black. However, the black pearl jewelry can only grow in fresh water containing trace elements of manganese freshwater clam shell beads and freshwater pearls inside layer. In the long sea life Epiphytic and natural pearls cultured pearls in the nuclear mother of pearl outer layer, do not change color. In other words, after dealing with radioactive nuclear black pearls, black color comes from the mother-of-pearl, is attached through the black Health, in its colorless on the nacre, so that the nuclear black cultured pearl beads showing the colors. Yong of irradiated that the Law Reform Commission of the color of the Black Pearl, also known as the international business Akoya pearls.
Identify with the naked eye color change on the basis of the Black Pearl, the following points.
The color distribution of the Black Pearl stained uniform color, but there are lesions, cracks, gathered deep black. If you hold on the Black Pearl doubt, you can use cotton dipped 20% of dilute nitric acid solution, staining on the surface of the Black Pearl scrub, cotton balls will leave a black mark. The powder color of natural black pearl powder color is white, and the staining of the Black Pearl powder color is black. If the Black Pearl on the small holes are drilled, the needle can be picked from the hole, but a little powder can identify. This is a destructive practice, so to speak very carefully, in particular, can not drill the House on any depiction of the Black Pearl.
Watching the natural core of the Black Pearl homogeneous structure, there is no core. The use of radioactive radiation color to the nuclear black pearl farming in the 0.5-2mm thick layer of white pearl inside, a black core from a drilling of the Black Pearl, 10 times the magnifying glass to peer in to see Qing. But not for the drilling of the Black Pearl, the law null and void.
Halo color after exposure to radiation color of the Black Pearl, the halo of color spectrum Nongyan father, accompanied by a strong metallic luster. Birth to a black pearl size of the education fucata, the figure is much more than the palm of your hand and butterfly bay. A culture of After more tablets of the Black Pearl, rarely less than 9mm. Therefore, there is less than 8mm round of the nuclear black culture, green or gray blue-green pearl under normal circumstances may be the exposure to radioactive color products
