Palladium and platinum are both platinum group elements, and their metallurgical properties are quite similar. They are all silvery white and similar in appearance. Because they are rare metals and have similar uses, they often replace each other in various applications. However, they are two different white metals. The difference is that the element name of palladium is palladium, the element symbol is pd, the atomic number is 46, the hardness is 4 ~ 8, the relative density is 12 ~ 02, and the melting point is 1555℃. The name of platinum element is "platinum", the element symbol is "pt", the atomic number is 78, the hardness is 4 ~ 3, the relative density is 2 1.45, and the melting point is 1700℃.
Apart from the above differences, palladium is cheaper than platinum. Therefore, the sales staff selling jewelry must not be vague when introducing goods, thus misleading consumption. We must clearly tell consumers the differences between them and their respective advantages and disadvantages, so that consumers can take their own needs and clearly consume, thus establishing a good image of enterprise's honest and orderly operation.
In the past, there were only three kinds of precious metal jewelry in our national standard: gold, silver and platinum, and there was no palladium. Due to the high price of platinum, it exceeded $900 an ounce some time ago. In the past, jewelry manufacturers could not do it, and many consumers could not afford the price. Now the price of palladium is relatively low, only about $200 an ounce. Because palladium ornaments are also white and light, manufacturers are profitable to consumers. So in the last month or two, many enterprises are producing palladium ornaments in large quantities. Palladium jewelry became popular in this situation. Now the national standard of precious metal jewelry has been revised, even Pd (palladium) jewelry has been included in the standard.
Platinum, also known as pure white gold, is a natural white precious metal. The annual output of platinum is only one twentieth of that of gold; White luster is natural and will not fade after long-term wear; The hardness of platinum makes it the best friend of diamonds, and most of them are inlaid with diamonds. So the price is very expensive, which is the highest among all precious metals. In China, platinum ornaments are generally marked with "PT", and the purity is expressed in thousands.
Although palladium is also one of platinum metals, it is also a natural white precious metal. In China, palladium ornaments are generally marked with "PD", and the purity is expressed in thousands like platinum.
Because palladium has almost no impurities, its purity is extremely high, it is very suitable for skin, and its market price is much cheaper than platinum (the price difference is nearly 4-5 times), and it is gradually replacing platinum as a fashion trend in jewelry industry.
Among the above two kinds of ornaments, platinum is expensive, pure and elegant, and palladium is suitable for skin care. Consumers Association specially reminds consumers that when buying platinum jewelry, the key is to have a price positioning in mind first, and to identify the logo according to their own positioning when buying.
