How much does it cost about gold and silver and white gold bracelets

Valuation: HKD8,500-11,500 yuan

[Edit this paragraph] 1 White Gold
The so-called K platinum and platinum on the market, in fact, it is a kind of gold, nickel, nickel, nickel, Copper and zinc alloy. 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 (White Gold), which means white gold. In the early days, 226 (60 % of gold, 钯 20 %, and 20 % of copper) represents white gold containing 600/1000, which is commonly known as "material", which means silver white metal containing gold, instead of not gold without gold, not gold without gold, not gold without gold, not gold without gold, not gold without gold, not gold without gold, not gold without gold. Nickle Alloy electroplating. Generally use abroad; WG585 (14K), WG750 (18K), or only the gold content with digital.
The white gold has good reflexity and is not easy to lose luster. Before the use of platinum and 钯 in the future, white gold is mainly used to inlay gemstone silver white metals.
[Edit this paragraph] 2 platinum (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. It is chemical and stable.
The pure platinum is relatively soft, and adding metals such as 钌, 铑, and 钯 will increase its hardness. South America's Indian people produced platinum jewelry as early as the 15th century. Europeans began to adopt until the middle of the 19th century. At present, China is the largest consumer of platinum. The platinum imported by each year accounts for more than 60 % of the world's total output.
[Edit this paragraph] 3 platinum alloy (Platinum AlLoy)
The alloy made of platinum is mixed with other metals, such as 钯, 铑, 钇, cobalt, cobalt, 锇, copper, etc. Although platinum hardness is higher than that of gold, it is still not enough to use it as a mosaic. It must be used to make jewelry with other metal alloys.
This use of platinum, cricket alloy and platinum, and crickets are used. 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.
[Edit this paragraph] Palladium
is a member of the Platinum, silver -white, symbol PD, a proportion of 12, lighter than platinum, strong ductility, slightly hardened than platinum, insoluble in soluble in, insoluble in it Organic acid, cold sulfuric acid or hydrochloride. 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 platinum 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 PD1000, PD950, PD900
[Edit this paragraph] The difference between 5 platinum and platinum n The official explanation of the International Platinum Association:
[Platinum (PT), which is a kind of Naturally generated white precious metal. The state regulations can only be called platinum jewelry only with a platinum content and top jewelry, and must have a PT logo. Platinum jewelry usually has a purity logo of PT850, PT900, PT950, or PT990. Therefore, platinum jewelry does not exist so -called 18K or 750 (ie 750 ‰) purity).
White Gold, its main ingredient is gold, it is not natural white, and it is white because it adds other metals. White K gold is not platinum (platinum). White K gold jewelry usually uses 18K or 750 to indicate the purity of the gold contained in it. ]
It this shows that in China, only platinum is called platinum; please refer to the "Platinum Credit Card" series launched by major banks.
platinum is an element, and platinum is a mixture. Platinum: Platinum (PT), which is more stable than gold, and the price is more expensive than gold. It is used to make high -end jewelry. The "PT900" or "PT950" seen on the products of jewelry stores represents the content of platinum in the jewelry of 90 % and 95 %, respectively.
The common name of platinum is platinum, platinum is pure white, and the natural platinum reserves are scarce than gold, so the price is more expensive than gold. Platinum can keep white diamonds maintaining the original color and firmness. It is the best material inlaid with diamonds. It is a superstar for diamonds to make platinums as precious metals. Most of the inlaid inlaid in my country is PT950 and PT900, and PT900 is the most commonly used.
The provisions of the platinum jewelery in the "Pure and Naming Methods of Jewelry and Precious Metals and Models", the total content of platinum and pupae must not be less than 950 ‰. Platinum jewelry is crowned with platinum or PT with a purity of thousands. Example: 990, PT990 or Foot Platinum.
This platinum is relatively soft. If you want to inlay diamonds, you must form alloys. Even adding 5%of the alloy can make PT hardening and meet the processing requirements. Some of the alloy components that are added must be platinum metal.
The purity allowed by Japan to be 1000.950.900.850, and can have a small (0.5%) negative difference. The purity is 850PT for chain, and the PT900 is the most commonly used purity. Since Japan is the most important export market in Hong Kong, Hong Kong uses Japanese standards.
If the United States stipulates that purity is called PT, at least 50%of platinum must be contained, and a total of 95%of platinum metals. Platinum content, which is higher than 95%, can be put on PT mark. Jewelry with platinum content between 75%-95%must also be marked with platinum metal. Jewelry with platinum content between 50%-75%must be put on the name and content of the platinum metal metal. Such as 585 platinum 365 (). Only the United States allows "K platinum" alloy.
The proportion of platinum alloy: PT950 --- 20.64 PT900 --- 19.88 PT850 --- 19.18
The difference between K platinum and platinum. Strictly speaking, K platinum cannot be equivalent to platinum. Platinum is a precious metal that is naturally white itself. At present, it is the highest price among all the precious metals. The commercially available platinum jewelry has a "PT" logo. This is the English abbreviation of platinum. K platinum is a white alloy made of gold and other metals. The so -called 18K platinum is actually synthesized by 75 % gold and 25 % of other metals. Therefore, K platinum cannot be put on the "PT" logo, and it can only be marked with gold and purity according to its purity. For example: 18K Platinum can only play marks such as "18K" and "G750". So, how to simply identify the two? First of all, buying these valuable jewelry must be reliable to buy from a large shopping mall. The most important thing is to see the label and see if the jewelry is "K" or the "PT" logo.
time when buying platinum jewelry, the operator should ask the operator to issue an invoice. Write whether it is platinum or white 18K gold in the invoice. It is best to indicate the weight of the jewelry, so that it is easier to claim when the fraud occurs.
