Besides platinum, gold and silver, what other precious metals are there?

The first thing to explain to the landlord here is what precious metals traditionally mean. Traditionally, precious metals generally refer to eight kinds: gold, silver, platinum, palladium, rhodium, iridium, ruthenium and osmium. Although the prices of other rare metals are similar to these eight kinds, when it comes to precious metals, people will only say these eight kinds!

Answer the landlord's question. Precious metals used to make jewelry must have good processability, stable chemical stability and safety to human body, not to mention gold, platinum and silver. At present, in addition to the first three kinds, there is also a common one on the market.

Palladium, chemical symbol Pd, is also very stable in chemical properties, easy to process and safe for human body.

In fact, people who generally don't pay attention to precious metals may not know that there is actually another precious metal that will be used in jewelry in a small amount and is extremely expensive, that is,

Rhodium, chemical symbol Rh, is the highest price among precious metals, and it is difficult to process, so it can only be processed by heat. At present, it is difficult to see jewelry made of this material in the international market. Only a few foreign companies accept customization, and the price is extremely high. But at present, rhodium does have the trend of being widely used in jewelry in the future.

Ruthenium and Hunger, two metals, are too difficult to be made into jewelry, and they are easy to produce toxic volatiles after heating, so they will not be used in jewelry.

As for other non-precious jewelry, it's just like 1 building!
