As far as diamond rings are concerned, platinum diamonds are 18K platinum diamonds. In fact, platinum and diamonds are standard, one is the hardest, the brightest and the most stable.
However, platinum is expensive and expensive, and the production process is complicated and it is difficult to recover it. Jewelers prefer to use 18K platinum pairs to create diamond rings.
Everything expensive in this world is scarce. Even if it is not scarce, it is an oligopoly. Anyway, you can see that it's rare, so it's expensive. Platinum is really scarce. There is a saying that pouring all the platinum in the world into an Olympic standard swimming pool can't cover the instep, and gold can fill three swimming pools. The most important reason why platinum is expensive is its rarity. If it is the same as the big iron mine, even if it is not discolored and unstable, it will not be expensive, and we will not want to wear it.
China has less platinum reserves, and the main producing areas of platinum are South Africa, Russian and Canadian. The annual output of platinum in these three countries can account for about 95% of the world output, while the annual output of platinum in China is only 1% of the actual demand of platinum in China.
The demand for platinum I am talking about is not jewelry, but industrial use, which is just needed. Due to the increase of these demands, the price of platinum, which is already scarce, is much higher than that of gold.
Platinum has excellent stability, excellent catalysis, acid resistance, alkali resistance and high temperature resistance, so it is used in various automobile-driven chemical plants. Due to the rapid development of these industries, the demand for platinum is increasing.
Some people will say that as long as the output is so stable, it can be recycled. I've thought about it before, but in fact, you spend 5 thousand on a piece of gold jewelry and weigh it by the gram. One day you are short of money and want to sell it. Normally, you won't lose a lot of money. According to the gold price of the day, 20 yuan or 30 yuan can be given a maximum discount per gram. If gold goes up, maybe you can earn a smile.
But platinum can't. I have a small platinum ring. I once visited a department store and saw someone recycling platinum, platinum and gold. I went up and asked how much this ring could cost. The boss looked at it for a long time and gave me an offer 1 100. .
Me: Isn't it recycled by the gram?
Boss: Did you buy it by the gram?
Me: No, if you don't weigh it by grams, you can put it on the scale to see what to do. Then what should you recycle it through?
Boss: I just estimate. I don't want to accept platinum. You sold it. Don't sell. Selling platinum is not cost-effective.
Me: Platinum is badly preserved. Why is it so expensive when you buy it?
Boss: The recycling and purification process is very complicated, the cost is too high, and the jewelry process is also complicated. You see, there is very little platinum in small jewelry stores, and platinum jewelry of big brands is also sold by the piece, so the working hours are too high. You have seen jewelry stores selling pearls and gold by the gram, and they are all pieces. Don't even think about selling platinum jewelry. It's fun to wear As long as it doesn't change color and fade.
Another reason is that the mining cost is extremely high, which is about 10 times that of gold mining. This data is not accurate. You know it's hard anyway. It takes about half a year from ore mining to platinum mining. This data is not accurate either. This may be right.
Summarize the reasons why platinum is superior to Huang Jingui:
1 is rare and monopolized by a few countries.
2. Compared with gold mining, the cost is much higher.
It is widely used and can't be replaced by other metals.
4. The craft is more complicated than gold.
