Pearl purchase needs to know 7 major considerations Yellow Pearl treatment skills
Pearls are loved by many people in their noble and beautiful form. What problems should you pay attention to when buying pearls? China Jewelry Merchants Network Xiaobian you compiled the seven major considerations when buying pearls for your reference. 7 major considerations for pearl purchase: 1. Color: Light color is distinguished by body color: pink, white, cream, etc.; the best reflected light in light color is pink. Black: Black, dark green, blue, purple, etc. Among them, the black pearl has the best quality of green reflected light. In addition to the above colors, there are peach, yellow, gold, and the like. 2. Gloss: It has a great relationship with the density of the nacre. The close texture can exude a bright and moving radiance. The tightness of the texture is taken from the water temperature. The lower the water temperature, the slower the growth rate and the denser the texture; the higher the water temperature, the faster the growth rate, the looser the texture, and the less luster. Take Japanese culture pearls and Nanyang pearls as an example. The sea temperature in Japan is low. The nacre is about 1.5 mm long each year. The South Sea pearls are in a warm zone, and the bead layer grows nearly 3.0 mm per year. 3, the thickness of the nacre: the thicker the nacre, in addition to the good skin light, if there is any scratches, it will not immediately reveal the central tuberculosis. The ideal bead thickness is about 4.5 mm to 5 mm. 4, shape: Beads have always been the most popular, but in recent years pear-shaped pearls are also becoming more and more popular, and the deformation beads are often the designer's ingenuity to become a beautiful jewelry. 5, ç‘•ç–µ: must consider the size, location and obvious or not, directly affect its value. 6. Workmanship: The primary consideration is the compatibility of the pearls with the materials used and the compatibility of the pearls. If you look carefully, the size of the hole is also one of the factors that affect the price. 7. Size: Although the size of the bead is a big factor affecting the price, for a whole necklace, the pearl can be evenly matched in color and size, so it is even more rare; so we can understand it. Why can a string of pearl necklaces reach a high price? How to effectively treat pearls to yellow: Why does the pearl jewelry use yellow for a long time? This is mainly because the physical properties of the aragonite minerals that make up the pearl are unstable. After a long time, it will become an ordinary calcite. Aragonite and calcite, although their chemical composition is the same, their crystal form and luster are not the same. This is the reason for the discoloration of the pearl. After the pearl turns yellow, there are some remedies, that is, soaking with dilute hydrochloric acid can dissolve the yellowed outer shell, and the pearl will reproduce the brilliant and radiant color. But if the color becomes very powerful, it will be difficult to reverse.
