The difference between platinum and platinum

Platinum and platinum are both natural precious metals. But there are essential differences. Their chemical properties are more stable than gold, and the price is more expensive than gold. They are often used to make high-end jewelry. So what are the differences between platinum and platinum? It is a detailed answer provided by Diamond.com. The difference between platinum and platinum Platinum and platinum are both natural precious metals. But there is an essential difference. Their chemical properties are more stable than gold, and the price is more expensive than gold. They are often used to make high-end jewelry. So what are the differences between platinum and platinum? The following is a detailed answer provided by Diamond.com: One of the differences between platinum and platinum: the concept generally refers to platinum, and its full name should be'white k gold'. It is a platinum-free white alloy made by smelting gold and other white metals. Among them, the percentage of gold is at most 75%. Because this alloy appears white, it is called platinum. The name of platinum comes from the Spanish'platina del pinto', which translates to the white metal similar to silver in the pinto river. Metals smelted from platinum group element minerals include palladium, iridium, platinum, rhodium, etc. Generally, platinum is smelted from platinum ores such as natural platinum and crude platinum ore. It is a rare precious metal that mainly contains platinum or is composed entirely of platinum, and is a precious metal equivalent to gold and silver. The second difference between platinum and platinum: composition 　　 platinum is an element, white 18k gold is a mixture containing gold (au) and a small amount of other metals. In the chemical element table, white k gold is gold, and platinum is platinum. Platinum (pt) has more stable chemical properties than gold, and is more expensive than gold, and is used to make high-end jewelry. The'pt900' or'pt950' seen on the products of the jewelry store means that the platinum content in the jewelry is 90% and 95% respectively.　The third difference between platinum and platinum: purity 　The general purity of platinum jewelry is 95%, while the purity of 18k gold is only 75%. No metal can be completely pure, there are impurities, doped with other metals. Platinum has almost no impurities and is extremely pure, so it will not fade or change color, and it can still maintain its luster through the passage of time. The pure white luster of platinum reflects the true light of diamonds very well. White K gold is a mixture containing gold (au) and a small amount of other metals, and the highest purity available on the market is 75%. It is a mixture of 75% platinum and 25% silver, nickel, copper and other metals, which is white k gold. Labeled as 18k white gold, 750 white gold, 750g, etc. The fourth difference between platinum and platinum: the mark of white k gold should indicate the k number. K refers to the gold content. For example, the words labeled 18k white, 750g, 750 gold, and au750 are white k gold with a gold content of 18k. The purity of platinum jewelry is not indicated by'k'. The white karat gold and karat white gold jewelry sold on the market are not platinum jewelry. Platinum is chemically called platinum, and its seal code is'pt', which is also the chemical symbol of platinum, which is the abbreviation of'platium' in English. Its elegant and simple color is innate. The content of platinum jewelry is calculated in thousandths, pt1000 is pure platinum, pt950 or pt900 is 950 and 900 parts of platinum. The fifth difference between platinum and platinum: durability Platinum's density and weight make it more durable than other jewelry metals. All precious metals leave scratches, and platinum is no exception. However, scratches on platinum only move the metal and will not reduce its volume, while scratches on gold will cause wear and reduce the volume of gold. If there are visible scratches on the platinum, a qualified jeweler can re-sand it. White karat gold has lower alloy purity, but its wear resistance and hardness are better than platinum. If the diamonds are larger, platinum inlay is generally not as reliable as white karat gold. The sixth difference between platinum and platinum: Rarity Platinum is 35 times rarer than gold. In the world, it can only be mined in very few places, mainly in South Africa and Russia, as well as a few areas in Zimbabwe, Canada, and South America. Every year, only 88 tons of platinum are made into jewelry, while gold has 2,700 tons. The number of platinum mines is even smaller, with a ratio of 1:10 to gold mines.
