Extended data
According to the different types of gold, the rate of preservation is also different:
1. 18k gold is only suitable for wearing, and it is impossible to keep it. Because the gold content of 18k gold is 75% gold, the price of beautiful and fashionable 18k gold jewelry is much higher. It is ok to buy clothes. When it comes to the preservation rate, that's the worst.
2. There are other gold jewelry materials, not to mention 14k, but 18k, and 22k gold is not preserved with pure gold.
3. Needless to say, pure gold jewelry is ordinary pure gold jewelry, directly according to the sales price of the day plus some process fees. 3D hard gold is higher than the basic gold price and the process cost is more expensive. After all, exquisite and beautiful, beautiful and fashionable. Of course, the price is also higher than ordinary gold jewelry.
4. There are no complicated procedures for gold bars, and there are no excessive process fees. A very ordinary gold bar is sold at the gold price of the day plus a little handling fee, especially the gold bar in the bank, even lower than the price in the jewelry store. There is no excessive handling fee. Adding a little handling fee according to the trend of gold price on that day has an advantage over ordinary jewelry prices.
