Platinum has outstanding characteristics that other metals can't match: high density, toughness and wear resistance, and stable performance in various extreme environments, so it can remain as white as ever and never fade with time.
According to the person in charge of some jewelry processing enterprises, "the price of platinum jewelry has always been more expensive than that of gold jewelry, because the processing of platinum jewelry is more complicated than that of gold jewelry."
It is said that platinum has higher hardness and melting point than gold, so it will produce dazzling white light during processing, and workers must wear professional eye protection tools, which is indeed more difficult to process than gold.
It is more difficult to extract platinum than gold, and the energy consumption is higher: 10 tons of ore takes 8 weeks to extract 1 ounce of platinum; In contrast, 1 ounce of gold only needs 5 tons of ore in 5 days. At the same time, processing platinum requires a higher technical level than processing gold, and every step of the process needs to be very precise.
My personal guess is that not only the protective gear is inconvenient to operate, but also the protective gear itself should be calculated. Therefore, combined with other reasons, the processing cost of platinum is much higher than that of Huang Jingui. So in the end, although platinum is lower than gold in transaction price, it is still higher than gold in finished jewelry.
