Which is more expensive, gold or platinum? The platinum ring I bought before was replaced by a gold ring of 18k. Did you lose money?

Almost all people who like gold can't tell this gold from that one. Friends are often fooled, which is a headache! 18K gold, rose gold and platinum are all the same things. 75% gold and other worthless metals increase the hardness, so it is easy to engrave, and the price is fixed on the manual fee (in fact, it is not that expensive, so it looks more expensive than pure gold). There are thousands of pure gold and pure gold, namely 999 and 9999. Platinum is several times rarer than gold! More than Huang Jingui.
