Platinum is made of natural platinum and other raw platinum ores. Platinum is called white platinum for its silver white. Its hardness is 4 to 4.5 and intense is 21.45. Its melting point is 1773 centigrade. It has a quality of fixability and can be stretched into thin platinum string or pressed into thin piece. It has a stable chemical quality and can hardly be corrupted by strong acid. Thereupon, it is wildly used in jewelry industry and chemical industry. It can be used to make junior chemical contents or used as catalytic agent to increase the action between chemical materials.
In jewelry industry, platinum can be used for three kinds of platinum jewelry.
The first is pure platinum jewelry. It is of the highest quality and often used for wedding jewelry to show the eternal love between two people. In foreign country, many people think that the diamond will turn yellow if it is set by gold, which will degenerate the value of diamond. However, if the diamond is set by platinum, the platinum can at least guarantee the pure white of the diamond. It is especially necessary when you are going to get married; the diamond set in the platinum symbolizes the pure and eternal love. However, platinum is not hard enough to set diamond even though it is harder than gold. It is usually necessary to add some other metal in to make a kind of platinum alloy to set diamond.
The second is a kind of alloy consisting of iridium and platinum. It has a silver white color and is strongly glossy. It has a high hard and a huge intense as well as a stable chemical quality, which makes it the excellent material fro platinum alloy jewelry . It can be divided into three varieties according to the different components of it.
The third is white K gold which consists of gold and other metals. Because platinum is a rare expensive metal with high melting point, few people use it to make the rare white K gold. Some people choose gold mixed with silver, copper, nickel and zinc to make a kind of white alloy which is called white K gold. This kind of manufacture is to cater to consumers for their love of platinum jewelry. The content of white K gold is similar to the K gold, which is that the content of gold in it is the same such as 18 white K gold or 14 white K gold. The content of gold in them is 75% and 58.5% respectively.This paper from the http://www.jewelryshopvip.com
