Is there a yellow dot on the jade that affects the appearance?
If it is a bright yellow spot with a small particle distribution, this is called "saling gold", but it can enhance the value and appreciation of the bracelet. If it is a dark brown spot, it should not be ugly. This is called "ç¿¡". Will not affect the value.
Will sweat corrode jade?
Yes, but the corrosive effect is very weak, the jade is more and more transparent, because of the erosion of sweat, the pickling step of the jade B goods imitates this, but the degree of corrosion is too strong. Wearing it on the body is A, and it is still a strong by the corrosion of sweat, it will not affect its price. The negative effect caused by corrosion can basically be completely ignored. As for the surface of the jade, its surface finish is generally caused by stains, and has nothing to do with the corrosion of sweat.
What should I do if the jade falls out of the crack?
If you want to save money, find a jade master to perform secondary waxing and polishing.
If the bracelet is well watered, you can go to the jade shop to find the master Jin Baoyu (golden jade) to cover the crack, which is beautiful and valuable but costly.
How to identify jade A, B, C goods
The jadeite currently operated on the market is divided according to the true and false. Mainly divided into A, B, C, D goods.
A goods are pure natural jade, only polished and polished. It has not undergone any chemical treatment and has not been subjected to artificial heat such as high heat and high pressure. It is a natural color, undyed or electro-colored, and is called "positive color" or "true color". The texture of the naked eye is fine, the color is soft, the stone pattern is obvious; the slight impact, the sound is crisp and sweet; the handcuff has a heavy feeling, which is obviously different from other stone. It is characterized by a density of between 3.32-3.34g/cm3, a refractive index of 1.66, a glass luster, a magnified structure observed in a magnified view, and no fluorescence under the ultraviolet lamp. The certificate of identification is marked as: "Jade" or "natural jade".
B goods will have black spots commonly known as "dirty" jade, soaked and corroded with strong acid, destroy the molecular structure of jade, remove "dirty", "mian" to increase transparency, and then use high pressure to inject epoxy resin or alternative filling into strong acid In the micro-cracks generated by corrosion, it acts to fill, consolidate cracks and increase transparency. A slight impact, the sound is boring, there is no crisp sound of A goods. B goods at first look good color, but carefully observed, the color is dazed and evil, under the light to observe, the color transparency is weakened. Due to the destruction of the original quality of jade by strong acid, B goods will gradually lose their luster in two or three years, cracks appear, and long-term wear is harmful to the human body. The certificate of identification is marked as: "Jade (handling)".
C goods are completely artificially colored. The color is not correct, evil, and careful observation, the color does not exist naturally in the jade, but is filled in the cracks of the mineral, showing a network distribution, no color roots. Observed with a Charles filter, the green color turned red or colorless. Wipe with a strong fade word, the surface color can be removed or turned brown. Long-term wear is not good for health due to the injection of stains. The certificate of identification is marked as: "Jade (handling)".
After the B+C goods are soaked and corroded with strong acid, the color is added at the same time as the filling is injected, that is, the B-package treatment and the C-package treatment are simultaneously performed. The certificate of identification is marked as: "Jade (handling)".
D goods with other varieties posing as jade, divided into jade, glass, plastic. Jade class. That is, other jade is posing as jade. There are mainly Thai jade and Malaysian jade, Nanyang Dushan jade, Qinghai jade, dense jade and Australian green jade and Dongling stone. The difference between these jade and jade: First, the hardness is low, and second, the density is small and the gloss is weak. Glass, plastic. Most of these alternatives are ugly and the gloss is very weak. The relative density is very light, the hardness is low, and there is no cold feeling. From this we can know that only A cargo jade is a natural jade, with wearing meaning and collection value, B, C, D goods can be called fake.
What should I do if there is a crack in the jadeite I bought?
There are often small cracks in the natural jade, so the so-called "Ten Cui and Nine" does not matter.
This is the case with the relatively rough machine trade unions, but it is not ruled out by the novice masters. If it is a few hundred pieces of pendants, it will be inadvertently pursued. If it is a few thousand pieces, don’t let it go. Road traces, high-grade jade, if such a low-level problem, it is already a quality problem
Can jadeite appear in dark green and emerald colors?
Dark green is iron to color, and green is chrome to color. These two elements replace the original sodium of the jade. Will make the jade appear two green. Natural conditions are entirely possible.
Jade maintenance
Jade has strong toughness, but don't misunderstand this feature as not afraid of being beaten. As everyone knows, jade also needs careful maintenance. When wearing jade jewelry, try to avoid dropping it from high places or hitting hard objects, especially jade jewelry with a small amount of cracks, otherwise it will be easily broken or damaged.
Jade jewelry is a symbol of elegance and holiness. If it is exposed to oil for a long time, oil stains will easily touch the surface and affect the brilliance. Sometimes dirty oily grease fills along the cracks of jade jewelry, which is unsightly. Therefore, when wearing jade jewelry, keep the jade jewelry clean, often wash it with a soft cloth in a neutral detergent, wipe it dry and then polish it with a silk cloth.
After the jade jewelry is carved, there are often waxes to increase its glamour. Therefore, jade jewelry cannot be in contact with acids, alkalis and organic solvents. Even unwaxed jade jewelry. Because they are multi-mineral aggregates, long-term contact with acids and bases should also be avoided. These chemicals can cause corrosion on the surface of jade jewelry.
Also, don't put the jade jewelry in the box for a long time. After a long time, the jade jewelry will "water loss" and dry out.
The above is the jade knowledge that Xiaobian brings you to know, more jade jewelry knowledge pays attention to jewelry culture , jade jade brand pays attention to jade brand , and brings you to feel green life.
