Use of palladium
Palladium is relatively stable, acid-resistant, almost free of impurities and extremely high in purity. It is suitable for skin. The international jewelry industry began to process palladium to make it into jewelry and decorative works of art. The jewelry made of palladium not only has the natural and charming luster like platinum, but also can withstand the tempering of years and last as long as new.
In recent years, the world has also developed precious watches made of palladium, such as Chopin, Cartier, Parmigiani and other world-class watches, which have pushed the newly developed palladium watches to the international luxury market. Palladium jewelry will be printed with manufacturer code, precious metal material and purity, so that consumers can distinguish palladium.
