Gold purity is often indicated by a hallmark or a stamp that denotes its fineness、The most common hallmarks for gold purity include:

24K or 999: This indicates that the gold is 99.9% pure、It's the highest level of purity for gold and is often marked as 999 or 999.9 to denote its fineness.

If you're referring to y999 in the context of gold, it's possible that:

1、It's a Specific Product: You might be referring to a specific gold product or item marked as y999, which could imply it's made of 99.9% pure gold、Without more context, it's hard to provide details about the item itself.
