Platinum is platinum, and PT is also platinum. Platinum is a chemical element, commonly known as platinum. Its chemical symbol is PT and the atomic order is 78. Platinum is a gray -white precious metal with high density, high ductility, and low reactivity, which belongs to transition metal. According to international regulations, only platinum can be called platinum, so the two are the same thing. It is a natural white precious metal. PD is gold. Gold, a member of the platinum, element symbol PD, similar to platinum, silver -white metal luster, bright color. The gravity is 12, which is lighter than platinum, and strong ductility. The melting point is 1555 ° C, and the hardness is 4-4.5, which is slightly harder than platinum. The chemical properties are relatively stable, insoluble in organic acid, cold sulfuric acid, or hydrochloric acid, but soluble in nitric acid and king water, which is not prone to oxidation and losing luster in normal conditions. Platinums: Brene wearing is not particularly particular about it. Do not wear heavy work or physical activity, which may cause scratches. The nature of platinum is very stable, and it will not deteriorate or fade because of daily wear, and its luster is always as early as the beginning. Even if you contact the common acidic substances in life, such as sulfur, bleach, chlorine in the pool, or sweat in hot springs, will not be affected, so you can wear platinum jewelry at any time. This of 讲 讲: 1. First of all, it is best to wear it alone to avoid mutual wear. 2, jewelry items should be prevented from pulling, squeezing, colliding, and friction. 3, regularly clean the gold jewelry. This ensures the best luster and more lasting. 4. All valuable metals may leave scratches, and gold gold is no exception. If there is scratches visible to the naked eye, please bring the gold jewelry to the jewelry store with qualified qualifications for polishing. 5. Try to avoid contact with bleaching or irritating chemicals. Pucting information: Platinum gold is often confused with white K gold on the market. But white K gold English is White Gold. The main ingredient is gold, because it is white after adding other metals, it is easy to fade. Platinum (Platinum) is naturally pure white and never fade. platinum = white gold ≠ white k gold. The most direct way to distinguish platinum is to find platinum propaganda in jewelry-PT or platinum. According to national regulations, the back of each platinum jewelry must be engraved with the proprietary symbol of platinum: PT or platinum (platinum), and after the sign, it is necessary to indicate that the purity of platinum is a thousand points containing platinum, such as platinum (platinum (platinum (platinum (platinum (platinum ( Platinum) or PT950, PT990, PT999, the latter two are commonly known as foot platinum and thousand -foot platinum. It is like a platinum ID card, and only the platinum propaganda -PT or platinum jewelry is the real platinum jewelry. The sign of the white K gold is AU750/G750/18K/Gold 750, which indicates that its 75%alloy material is gold, and then adds other metals to show surface white.

"PT" is the element symbol of metal platinum, and "PD" is the element symbol of the metal pupa. The difference between Platinum and Gold is as follows: 1. Seeing the signs of the two The chemical element symbols of platinum are "PT", and the chemical symbol of the gold gold is "PD". For example, PT999, PT990, etc. are platinum; PD999 and PD990 are gold gold. The two precious metals are only one word. When you look at it, you must be careful. 2. Their weight is different In the case of similar volume, their weight is different, because the density of platinum is nearly 1.5 times the density of the golden gold, and platinum is obviously better than the gold gold. Weighing heavy. 3. Use the feel to judge The feel of platinum is significantly better than the golden gold, and even if the platinum is worn for a long time, it will basically not produce oxidation. Essence In terms of stability, platinum losses are smaller than that in the case of high temperature melting. This information: platinum and 钯 钯: The international jewelry industry is active in the unique chemical and physical characteristics of the golden jewelry industry, which makes it difficult to process jewelry processing. Therefore, the domestic jewelry industry is rarely used to make processing jewelry. However, due to the mastery of its performance in the foreign jewelry processing industry, a small amount of processing has begun to make it as a decoration and decorative artwork, and it has gradually formed a fashion trend. It, in addition to making jewelry, 铂 and platinum are also mainly used to produce automotive catalysts, electronics and dental medical appliances. Internationally not only uses jewelry, but also develops precious watches with 钯 钯 国际 after solving production technology. The world's top brand watches such as Chopin, Cartier, and Parma Johnny have pushed the newly developed Golden Watches to the international luxury market, and the price is equivalent to hundreds of thousands of yuan or even millions of yuan.

Platinum is a type of 18K gold. The gold content of 18K gold is 75 %. It is yellow and 25 % contains copper and other metals. The PT990 state stipulates that the gold content of more than 85 % of the gold content can enter the symbol of platinum. The PD is Pak to gold, which is the cheapest of these three. The market price of these gold is: Gold -18K Gold 230 yuan per gram, 270 yuan per gram of gold (excluding manual fees). platinum: PT900 380 yuan per gram, PT950 per gram of 430 yuan, PT990 per gram of 450 yuan. Pabin: PD990 about 80 yuan per gram.
. Quality 1. Poly -purity platinum jewelry, which is engraved with platinum jewelry with a PT950 logo with a purity of 95%; the purity of the PT900 logo is 90%.
2. The annual output of rare platinum is very limited. A ton of ore must be obtained by more than 150 processes to get a few grams of platinum.
3. The density of firm platinum is very high, and it is not easily damaged even in friction. Therefore, the jewelry made of platinum is very fine. All kinds of gems are inlaid with platinum, which is not easy to fall off.
4. Platinum's natural white metal luster is naturally elegant and subtle.
5. Platinum jewelry is easy to match with various types of clothing to create fashion classic at all times.
. The differences The two kinds of white precious metals popular on the market are platinum and K platinum. It is difficult to identify with the naked eye. Different methods: White K gold is commonly known as K platinum, which is alloy. "18K" or "750" is usually marked. Platinum is a natural white precious metal. Its content is marked with PT900 or PT950, so the mark must be recognized when purchasing. It is best to buy a secure merchant to buy.
. The market price is now PT950, about 260-300, (see the city) men's platinum ring is larger.
. The meaning of foot platinum is a platinum jewelry marked with PT950 or PT900 is called foot platinum jewelry.
. The meaning of k gold Due to the addition of different metal elements, K gold can present a variety of colors such as yellow, white, red, and green. No matter what color K gold, its gold content is 75%, marked "18K" or "750". There is a essential difference between white 18K gold and platinum. Whether it is texture or value.
6. Platinum and gold (Special Tips) Platinum logo: PT; 钯 钯 ：: PD. From a price point of view, the golden gold is much cheaper than platinum; in terms of texture, the golden gold is light, it is easy to crack, and the color will be darkened for a while, and the above problems will never occur.
What is platinum? Platinum (English Platinum abbreviation PT) flashed dazzling light in the history of human civilization as early as 700 BC. Successfully mastered the processing process of platinum and made different styles of platinum jewelry. In the 18th century, the French king Louis XVI prefers platinum, saying that platinum was "the only precious metal that matches the title of the king". In modern times, world -renowned jewelry design has created immortal masterpieces with platinum. The world -renowned Hop (Hope) diamonds were also inlaid on the platinum chain forever. At the beginning of this century, platinum has become the most favorite precious metal in the United States. Its natural white gloss conquered the hearts of countless nobles. After the outbreak of World War II, platinum has important military use. The U.S. government once banned platinum non -military affairs, and used white K gold (gold and other white metal alloys) instead of platinum. Although white K gold is from luster, hardness and other aspects, platinum is never replaced. Today, the use of platinum jewelry has to continue. Its rare, pure, hard characteristics, and their natural white luster still make men and women pursue fashion. It is said that platinum is rare because the treatment of platinum is far lower than gold. So far, the global platinum reserves are enough to fill a medium -sized room. One ounce of platinum needs to be refined from 10 tons of platinum ore. It is said that platinum is pure because platinum jewelry usually contains 90%of pure platinum, and other 10%of platinum metal. In contrast, 18K white K gold contains only 75%of pure gold, and the white luster of platinum is naturally natural, and long -term wearing will not fade. It is said that platinum is hard because the density of platinum is high, and the intensity is almost twice gold, which has become the best choice for inlaiding various accuracy. Due to the goodness of platinum, one gram of platinum can pull out 2 kilometers of filament for years. The hardness of platinum makes it difficult to wear, while platinum is long and eternal. The inherent value of platinum and its elegant gloss inspired countless jewelry designers, and the jewelry world or fashion is keen to set off the "white wave" again. French designer Cartier claims that platinum jewelry is "the king of precious metals": Platinum wire was used in its designed evening dresses: also used platinum filament to weave its evening dresses. The design of platinum jewelry is constantly new, of which Japan is the largest market as platinum jewelry. Its platinum jewelry is particularly representative. Japanese platinum jewelry is finely worked, from casting to polishing, all of which are improving. The design style is both fashionable and subtle. Each jewelry is like art. As the world's second largest platinum jewelry market, China still needs further improvement in design concepts and processing technology to meet consumers' needs for personalized and fashionable jewelry. To this end, the International Platinum Association will be held in Shanghai in early July in Shanghai. For the first time of jewelry designer expert lectures, Mr. Sekikazu, one of the top ten famous jewelry designers in Japan, taught the design concepts and skills to Chinese platinum jewelry teachers. In general, simple lines, subtle ideas, and fine processing are currently fashionable design of platinum jewelry. To this end, Thai platinum design is talked about by designers, because the silver white and lines of the metal itself can be made into a lot Modern work with a strong sense of modernity. The passage of the years did not take away people's love for platinum, but added the beauty of platinum. The charm of platinum is that it brings people a peaceful aftertaste from the inside to the outside. Real, its pure, and elegant temperament, none makes people feel that platinum is worth having. ■ Seven characteristics of platinum 1． There are 95%of the pure platinum with the highest pure platinum alloy with a gold with a 75%gold. A platinum jewelry has a higher purity than gold jewelry. 2. The rarerity of 140 tons of platinum is produced in the world each year, and the annual output of gold is 3,300 tons. 3. Only the skilled craftsmen can make it. The melting point of platinum is higher than that of gold, so it is more proficient in the technical requirements of workers. 4. The most stable platinum is the most resistant metal to acid, alkali, high temperature, etc., and will not fade or change color. Platinum rings generally do not deform. 5. The luster and ductility of platinum have natural white and gloss, which will not affect the color of the gem, and it can make gems release glory and "fire", and good ductility also makes it suitable for processing. 6. It will definitely not make the jewelry a allergic reaction. 7. Valuable and outstanding. ■ The symbol of platinum in international platinum is PT, Plat or Platinum, and represented by pure thousand points, such as PT900 indicates that the purity is 900%O. The specifications of platinum jewelry are marked with PT1000, PT950, PT900, and PT850. The purity is expressed at the lowest value, and there is no negative difference. The purity range of platinum is shown in the table. Platinum alloy jewelry should comply with the provisions of the table below, and the total content of platinum and pupa should not be less than 950 ‰. ■ Platinum type pure platinum: the highest color platinum. Commonly used for making engagement rings to show the pure virginity of love. Many people think that inlaid diamonds with gold may cause diamond yellowing, which greatly reduces the price of diamonds. With platinum inlaid diamonds, the pure white color of diamonds can be kept, especially as an engagement ring. Platinum inlaid diamonds with platinum are both white and crystal. However, although platinum has higher hardness than gold, inlaid diamonds and jewelry are still insufficient, and they often need to be mixed with "gold" to make "platinum alloy" to inlay diamonds. Platinum: alloy composed of 铂 and platinum. The color is also silver -white, with strong metal luster. High hardness. The relative density is also large, and the chemical properties are stable. It is an excellent platinum alloy jewelry material. ■ The difference between platinum and K platinum platinum: It is a precious metal that is naturally white itself. The annual mining volume of platinum is only one -twenty of gold, and a ounce of platinum needs to be refined from 10 tons of platinum ore. Domestic platinum jewelry usually contains 90%of pure platinum and is attached to the "PT900" logo. White K gold: It is white after gold and some alloys. It only contains 75%of gold. White K gold cannot be beaten on the PT logo, and it can only be marked by the purity of gold and purity according to its purity. For example: 18K white K gold can only play marks such as "18K" and "G750". In the international precious metal market, the price of platinum is far more than gold, and the highest price among all precious metals. In addition, some white jewelry may also be silver products or white metals plated on its surface. Over time, it may show the original appearance. Although platinum is sometimes commonly known as platinum, in a strict sense, it should be called "platinum". Platinum English Platinum means chemical element platinum. Therefore, the purity, scarcity, durability of platinum, and its natural white gloss are not comparable to white K gold. ■ Platinum reserves Due to the scarce reserves of platinum in nature than gold, according to incomplete statistics, the world's total platinum storage is about 14,000 tons (the total reserves of platinum elements mineral resources are about 31,000 tons). Many countries have discovered and mined platinum ore, but their reserves are highly concentrated in South Africa and the former Soviet Union. Among them, the platinum reserves of South Africa (Azania) are about 12,000 tons, and the most famous platinum mines in Teramomi are the largest platinum mines in the world. Natural platinum weighing 8-9 kg was found in the platinum ore, and natural platinum weighing 427.5 grams was also obtained in native abnormalities. The total reserves of the two account for 98%of the world's total reserves. The annual output of platinum in the world is only 85 tons, which is far less than gold. In addition, it is more difficult for pure melting platinum to refine platinum than gold and high energy consumption, so its price is more expensive than gold.
Platinum English abbreviation is that PT is a kind of precious metal is rare, so it is more expensive platinum, which is commonly known as the low gold content of gold.
