cheap dog jewelry wholesale (1) Gold jewelry classification "Pure Gold" jewelry "Pure Gold" is usually divided into sufficient gold and thousands of gold. The color is red, soft, and shiny. But the absolute pure gold does not exist, as the saying goes, "gold has no redness." Based on the level of modern science and technology, the purity can be refined by 99.9999 % of reagent gold for standard chemical reagents. Due to the high production cost of reagent gold, it is of little significance to make jewelry with reagent gold in terms of use value. At present, there are three types of sufficient gold in the Chinese market: "Four Nine Gold", which is 99.99 % in color; "Three Nine Gold", which is 99.9 % in color, commonly known as thousands of gold; Commonly known as foot gold. 2. K -gold jewelry K gold is a alloy made of adding some other metals in pure gold to increase hardness, change color tone, and reduce melting points. Due to the different proportion of other metals, the nature, tone, hardness, ductility and melting point of K gold are different. The characteristics of K gold jewelry are that the amount of gold is small, the cost is low, and it can be prepared into various colors, and it is not easy to deform and wear, especially after inlaid gemstone is firm and beautiful, and it is also precious and beautiful. Therefore, many cities in my country are widely popular. The color of K gold jewelry is relatively rich. At present, the successful research is red K gold, orange K gold, yellow K gold, green K gold, blue K gold, cyan K gold, purple K gold, gray K gold, black K gold, black K gold, black K gold, black K gold, black K gold, black K gold, black K gold, black K gold, black K gold White K gold, white K gold is similar to that of platinum, especially plating a layer of 铑, which is elegant and generous. It can be false and true, but the price is much lower than platinum, so it is favored by many people. There are three main series of white K gold, namely: gold and 钯, gold and nickel, gold and silver, or their combination of alloy, can form white gold. (2) Simulation gold jewelry Gold -plated jewelry plated jewelry is mostly made of silver or copper, and the surface plating layer is gold. The golden luster replaces the original color of the original material, thereby increasing the ornamental value of the jewelry. The gold -plated gold content must not be less than 14K, and its thickness is not less than 0.5 microns. Gold -plated jewelry is generally lighter, and the bending is harder. In addition, the thin layer of jewelry can be exposed on the sandpaper to expose the base color. After the fire is burned, the color becomes white and the black is copper. 2. Gilt gold jewelry Gilt is a way of making jewelry in ancient times. It is to dissolve gold in mercury, and then evenly apply it to the surface of the jewelry. On the surface, it becomes a gold product. 3. The gold jewelry of the gold jewelry is made of silver, copper, lead, zinc, and other alloys, and then the gold foil is firmly wrapped on the surface of the metal product substrate in a mechanical or other method to obtain the gold coverage layer. The gold content of the gold must not be less than 14K, and its thickness is not less than 0.5 microns. (3) Maintenance of gold jewelry When wearing gold and silver jewelry, avoid contact with hard objects and pull hard. Due to the low hardness of gold and silver, contact with hard objects can be easily scratched or stretched, which will destroy the decoration of the jewelry. 2. Wear jewelry in a place with chemical pollution. At the same time, try to contact cosmetics such as perfume, head oil, flower dew water. Once you contact, you can easily corrode the surface of the jewelry and change color. In order to maintain the gloss of gold jewelry, you can often add a small amount Gently brush in the soft brush, rinse it with water, and then wipe and dry it with a soft cloth. (4) Test of gold jewelry 1． The mark of the logo should contain the name and content of the manufacturer's code, the precious metal material name and content. 2. The appearance quality is mainly the inspection of specific process quality of the overall shape and processing quality of the jewelry. 3. Jewelry weight gold jewelry is calculated based on weight and processing costs. The weight of the jewelry is one of the important indicators. The measurement unit of the decoration weight according to the standard is gram, and the average difference between the single parts of the gold jewelry is. 4. The gold content in gold content is an important indicator of its quality. There are many types of gold content testing methods, which can be divided into chemical analysis methods and instrument analysis methods. Depending on whether the jewelry is damaged during the testing process, it can be divided into non -destructive detection method and damage testing method. The daily inspection of the jewelry quality supervision department is generally based on non -destructive testing method. Utilize large instrument analysis. Market supervision random inspections are mainly due to damage testing. The fire test method is currently the national testing method that measures the gold content in jewelry in my country. (5) The physical nature of gold: red yellow, with a color of more than 95 %; positive yellow, the color is about 80 %; the blue yellow, about 70 %; the yellow is slightly gray, about 50 %. Density: 19.32g / CM3 hardness: Mohs hardness 2.5, which is similar to human nails. What is platinum, platinum, K platinum and gold in recent years, and in recent years, silver -white precious metals inlaid jewelry. In malls, the names of these precious metals are often at a loss. In Taiwan, these white metals are called by platinum and K platinum (silver is not discussed here). In fact, this statement often causes misleading and confusion. We must explain according to the naming of the elements on the chemical cycle table to get a reasonable name. First, Gold (GOLD): The so -called K platinum and platinum in the market are actually a alloy of gold, nickel, copper, and zinc. Or gold and silver, or alloy of gold, silver and copper. It also includes the alloy of gold and crickets often adopted by the Taiwanese masters. Its code WG (GOLD), which means white gold. In the early days, 226 (60 % of gold, 钯 20 %, and 20 % of copper) represents white gold containing 6001,000 pure gold, which is commonly known as "ingredients", which means silver white metal containing gold, instead of nickel without gold. Nickel Alloy electroplating. Generally use abroad; (14K), (18K), or only the amount of gold with digital. White gold has good reflexity and is not easy to lose its luster. Before the use of platinum and 钯 in the future, white gold is mainly used to inlay silver white metals inlaid with gem jewelry. Second, Platinum: Also known as pure platinum, positive platinum or real platinum. But these titles are unreasonable and easily confused with white gold. Its symbol is PT, silver gray-white, a gravity of 21.35, a melting point of 1700 ° C, and a Mohs hardness of 4-4.5 degrees. Chemical is refreshing. Pure platinum is relatively soft, and adding metals such as 铑 and 钯 will increase its hardness. South America's Indian people made platinum jewelry as early as the 15th century, and Europeans began to adopt until the middle of the 19th century. At present, Japan is the largest consumer of platinum. Third, Platinum AlLoy: refers to alloys made of platinum mixed with other metals, such as 钯, 铑, 钇, cobalt, copper, etc. Although platinum hardness is higher than that of gold, it is still not enough to use inlaid. It must be used to make jewelry with other metal alloys. The jewelry industry uses platinum, cricket alloy and platinum, and crickets. Platinum and cobalt alloys are used in Europe and Hong Kong. Platinum (85%) in Japan manufacture chains. The poke of platinum jewelry internationally is the word PT, Plat or Platinum, and represented by a thousand points of purity. For example, PT900 means that the purity is 900%O. The specifications of Japanese platinum jewelry are marked with PT1000, PT950, PT900, and PT850. Third, Palladium: It is a member of the platinum, silver -white, symbol PD, a gravity of 12, lighter than platinum, strong ductility, slightly harder than platinum, insoluble in organic acid, cold sulfuric acid or monitoring acid. But dissolved in nitric acid and Wang Shui. Under normal conditions, it is not easy to oxidize and loses gloss. The temperature will generate oxides on the surface of about 400 ° C, but the temperature will be restored when the temperature rises to 900 ° C. At present, it is cheaper than platinum. The jewelry industry is used alone, or it is composed of gold, silver, and silver alloy. Sometimes I participate in some crickets to increase their hardness. Common gold on the market, k k 市场, platinum, and 钯 alloy. Specifications are marked with the differences between PD1000, PD950, PD900 -platinum and platinum 1. Thousands of gold refer to pure gold jewelry with a metal amount of 99.9 %, and 999 or thousands of foot gold seals. 2. Foot gold refers to pure gold jewelry with a gold content of 99%, with 99%or foot gold engraved. 3. 18K gold refers to accessories containing 75 % gold ingredients, and the remaining 25 % are other precious metals, with 18K or 750 marks. 4. 18K Platinum refers to the gold jewelry containing 75 % golden ingredients and white gold jewelry. The remaining 25 % are other white golds and are engraved with 18K or 750 marks. 5. PT900 refers to platinum with 90 % platinum, and the remaining 10 % is other precious metals. Platinum and pupa contents with 950 % of platinum accessories are printed as PT900. 6. PT950 refers to jewelry containing 95 % platinum ingredients, and the remaining 5 % are other precious metals and the mark is PT950. The metal composition is completely different. On the chemical element table, one is Gold and the other is Platinum when buying jewelry to distinguish between true and false and quality? I. View the national standards of the mark, precious metal jewelry should be produced, manufacturers, materials and content marks, and unsproting products are unqualified products. If a quality problem, quality inspection agencies may be given inspection and judgment according to the mark. Consumers should purchase the brand they need and the gold jewelry of different gold content according to the mark. Second, sensory inspection method: 1. Look at color: Foot gold is dark yellow, K gold has yellow, red, white and other color, and most of the imitation gold products are copper alloys, and the color is lighter. 2. Oblique weight: The proportion of gold is much higher than the proportion of imitation gold products. For example, a foot gold ring is about 5 grams, and the same size imitation gold products are generally less than 3 grams. 3. Test hardness: Pure gold is soft, scratches with large head needles, bite tooth marks with teeth. Third, if you need to know the content of precious metal jewelry or quality disputes, you should go to the jewelry quality inspection institutions and use a physical or chemical analysis method for identification. When buying jewelry, you also need to carefully check whether the stones are inlaid, whether the welding is firm or broken, burrs, trachoma, etc. Maintenance of jewelry: When wearing and stored in gold jewelry, you should avoid contact with objects such as lead, mercury (mercury), etc., otherwise the surface of the jewelry will be discolored. Dry the jewelry during drying and bathing to prevent wear or bumps, let alone pull it hard to avoid deformation or broken. After wearing jewelry for a period of time, there may be dirt, dark color, soak with washing spirit, brushing gently with soft brush, rinse with water, and wear after drying. Platinum (platinum) basic knowledge platinum is also known as platinum. The symbol of chemical element is PT. It is silver -white precious metal. The hardness is slightly higher than gold, density (20.C), melting point 1768. C, it has many excellent characteristics, such as corrosion resistance, antioxidant, and beautiful colors. Because platinum has these characteristics, it can be used to make a beautiful and tough platinum jewelry. The jewelry, especially the white golden base, is inlaid with a flashed with a flashed with a fire color, and the pearl is combined to complement each other. It is currently the most popular jewelry jewelry. The type of platinum jewelry (common in the market) PT990 jewelry, also known as foot platinum jewelry, has a platinum content of not less than 90 %. The PT900 jewelry, its platinum content is not less than 900 %. The PT850 jewelry, its platinum content is not less than 80 %. The mark of platinum jewelry: Materials and content marks: for example: PT900, which means that the platinum content is not less than 900 %. Manufacturer's mark: For example: Beijing E, it means a manufacturer's production. Diamond weight: such as: D0.26, indicating that the inlaid diamond weighs 0.26 carats. Consumers should pay special attention to the mark when buying jewelry, and distinguish the platinum (platinum) jewelry from white K gold jewelry. The white 18K gold mark is 18K, and the platinum (platinum) is PT. Basic knowledge of silver jewelry: silver, chemical element symbols are AG, which are silver -white precious metals, low hardness, density, melting point 960. C, has good conductivity, ductility, and thermal conductivity. In addition to the use of electronics, medical, and photographic industries, it is also used to manufacture currency, jewelry, utensils, etc. Silver jewelry classification (common in the market) S990 foot silver jewelry has a silver content of not less than 90 %. S925 silver jewelry has a silver content of not less than 925 in thousands of thousands. The mark of silver jewelry: materials and content marks, such as: S925, indicates that the silver content of jewelry is not less than 925. Manufacturer's mark, such as Beijing A, indicates that a manufacturer is produced.
