Let's talk about gold first. Gold is almost the most popular metal ornament on the market. Its formation is very rare and takes a long time. In this long time, it will gradually have a very strong antioxidant capacity, so in theory, it will slow down the aging speed of people.
But this point has not been fully scientifically proved, so it can only be used as a hypothesis for the time being.
In addition, there is another interesting phenomenon, that is, men wearing gold rings for a long time will lead to the decline of gonadal function. Maybe this is God's punishment for mankind. It is true that marriage is the grave of life.
Platinum, on the other hand, is mainly composed of a metal called Pt, which is much more expensive than gold. This alloy has no effect on human body, but it has a great effect on physics.
For example, the thermocouple we often use when measuring the temperature of several thousand degrees is mainly made of PT. It is precisely because the use price of this metal is relatively high that its market price is relatively high, so it is generally not recommended to buy this metal, which has no effect except some scientific value.
In the current market, many people will confuse platinum with another metal platinum. Although there is no apparent difference between these two things, the main component of platinum is a metal that we often see-silver.
Moreover, silver is harmful to human body. Like the European aristocrats in the Middle Ages, many people were infertile because of excessive use of silver tableware, and many children were born unhealthy. So I suggest you don't buy this kind of metal ornaments.
