Wearing pure silver is good for you. This is because silver is a legendary metal-1,and its bactericidal effect. If the water contains1/200 million silver ions, all the germs in these waters will be killed. 2. it is its non-wear. During World War II, American nuclear physics laboratory urgently needed 2000 tons of non-oxidizing metal as wire rod, and the key was to smelt and process it for 36 times. It will probably lose 158 tons, and no one can afford this loss. Later, I borrowed 2000 tons of silver from the Federal Reserve Bank. After the atomic weapon experiment was completed, the laboratory found that the 2,000 tons of silver only lost 2.5 kilograms.
Platinum and gold are precious metals, which can preserve value. Gold represents wealth and platinum represents nobility.
However, platinum and platinum are one thing. The amount of platinum in the hands of human beings all over the world is less than 30 thousand tons, but it is used as a catalyst in the chemical industry. Pure platinum jewelry is not available. Generally, it is jewelry made of adjacent elements of platinum, such as palladium and zirconium. Don't trust jewelry made of pure platinum, just look good! ! ! ! ! !
