The platinum diamond ring on the previous market includes two types, one is platinum, which is usually nominated as PT950 gold. The English name is Platinum. In order to play PT marks, there are often PT950 steel prints on the inside of the ring. PT950 is international standards and national standards. Platinum output is scarce, expensive, and high melting point. Therefore, general countries rarely use platinum to produce real K platinum. After the outbreak of World War II, because platinum had very important military use, the US government once banned platinum non -military affairs, and used white K gold (gold and other white metal alloys) to replace platinum. It can never replace platinum. At present, in order to meet the needs of consumers for platinum, gold and cricket gold or nickel, silver, copper, zinc and other metals are used to melt into a white alloy, called "K platinum". The color of K platinum is the same as K gold. The quality of the bundle is 24, and the number of quality occupied by gold is the K Platinum KD. All marked 750 in the market, no matter what the previous symbols are, are 18K (24 divided by 18 equals 75%). There is no platinum in 18K Platinum. It is a kind of gold containing nickel and silver. Among them, 75 % gold contains gold, 10 % silver, zinc -containing 10 %, nickel -containing 5 %. The 18K steel print on the inside of the ring is not as white as platinum. Sometimes it is plated on the outside. It looks no different from platinum. According to the current market price, the price of platinum is about three times that of 18K platinum. "Platinum" is not a "platinum". The two are literally. One is beside it, a metal, and the other is emphasizing the color, but because of the pronunciation of Chinese, some people read platinum as platinum. The following points are for reference only:
1. Buying gold jewelry must first determine the price that you can accept, and then pick the style. Remember, the goods do not suffer than the three houses, don't rush to buy it, "the impulse is a devil."
2. Word printing: 18K material printing is generally labeled G18K or 750, platinum material is PT900 or 950 tag [Platinum content is not less than 990, and "foot platinum" or "PT990" mark; PT900; PT900 It means that the platinum content is not less than 900ths (that is, 900 ‰)]. Manufacturer's mark: such as Beijing E or H, which means produced by a manufacturer in Beijing. Diamond weight: such as D0.26, indicating that the inlaid diamond weighs 0.26 carats. In addition, there are also:
gold plating: It is plated on the surface of jewelry made of electrolytes on the surface of silver or copper. Even if the thin -layer gold plating may be greater than 0.05um, the gold -plated layer jewelry is marked with "GP" or "KP".
Back gold: Wrap the gold foil on the surface of metal materials such as silver, copper, and requires that the gold foil has not less than 10k, and the weight is not less than 1/20 of the total weight of the material.
Forging gold: In essence, it belongs to the packet gold. Under high temperature and high pressure conditions, the gold foil is forged on other metal jewelry
on the surface of the blank. The color of the gold foil is greater than 10K, and the total amount of K gold for forging should not be lower than the 5 % of the finished product. The standard
is recorded as "GF" or "KGF". Lost gold texture.
. Type weight: The same style, the same size, and diamond size, the jewelry of different materials, the PT950 material is heavier than the 18K hand, because the density of the PT950 is greater than the density of 18K.
4. See color: The color of the PT950 is slightly gray; the color of 18K is white.
5. Buying gold jewelry must go to a reputable formal merchant, because after -sales service is also an important aspect.
