The purity of gold generally refers to the gold content, and the higher the gold content, the more expensive the gold jewelry is not necessarily. For example, the price of 18K gold (75% gold content) jewelry is usually higher than that of pure gold (99% gold content) jewelry. Don't believe it? You can go to some big brand stores to compare.
Pure gold is generally based on the international gold price, plus a certain processing fee, rent, labor and so on. , and finally priced by gram; 18K gold is also affected by the international gold price, but the workmanship and design costs are higher than pure gold, and other gems may be inlaid, so the price is generally sold at a price, regardless of the weight of gold.
In addition, 18K gold is more popular internationally, such as top luxury jewelry brands Cartier, Tiffany's, Bulgari and Van Cleef & Arpels. , and 18K gold is often used to design products and styles.
Extended data:
"The higher the purity, the better the value" is basically no problem, but the current situation is that China people like to pursue the ultimate of "purity" and think that pure gold is not pure enough, so they pursue thousands of gold; One day, I felt that thousands of gold was not pure enough, so I pursued thousands of gold.
It is estimated that the big brother who controls this industry by the state can't stand it anymore, so he abolished the statement of thousands of gold and thousands of gold, and stipulated that all gold with a gold content greater than 99% is collectively called pure gold. The recovery price is also calculated according to the recovery price of pure gold, so there is no case that the value of 10 thousand pure gold is higher than that of thousands of pure gold, and the value of thousands of pure gold is higher than that of pure gold.
