Hello, although I am not a professional, I learned some identification knowledge from the waiter when I bought gold ornaments at Lizhi Gold Store. I hope I can help you. You can see if there are any standard marks.

Gold seal is generally like G750GXXX.

Or the bid price is 14K 18K 24K.

This is a national symbol.

You can also go to the gold and silver jewelry store for identification, and you can also identify the gold content.
