Excuse me, is the gold and platinum jewelry of zlf Leofoo Jewelry really pure gold?
The purity of gold is generally 99.9%, that is, thousands of gold. Platinum is gold with a gold content of 75%. You should have said platinum.
In fact, no matter what the clerk says, there will always be a material mark on the ring holder. Au999 stands for thousands of gold and pt999 stands for thousands of gold. If there is no or the number behind it is not 999, it should not be.
