I don't know if it is gold, but it looks very similar. There are 420 685
685 written on it. By the way, it is the decoration of a necklace I picked up.

Gold is divided into two categories: "Gold" and "Cooked Gold". Shengjin is also called "original gold", "natural gold" or "barren gold", which is a gold that people mine from the mines or the riverbed and have not been refined. All refined gold is called "cooked gold". Due to the addition of other elements in cooked gold, gold changes in color. People usually call the cooked gold that has been added with metal silver without other metals. The gold is called "mixed gold". K gold is a way of mixed color gold, 4.1666 % of gold ingredients are LK. Gold can be expressed as 24K, 22K, 20K, and 18K, etc. The golden color can also be represented directly with the percentage of the content. Usually, the gold weight is divided into 1,000 copies. For example, 9999 is 9999 % marked on the gold piece, and 58.6 % is marked at 586.

I suspect that it is not gold. The common words of gold jewelry are full gold, thousands of gold or 9999. There should not be these numbers. I suggest you go to test it
