5 thoughts on “What is the difference between Chinese gold rings with full gold and those without 999?”

  1. Answer:
    999 gold is also called thousand gold, and the gold content is not less than 999 ‰
    990 gold is called full gold, and the gold content is not less than 990 ‰
    the gold content of 22K gold is not less than 916 ‰; The gold content of 18K gold shall not be less than 750 ‰; The gold content of 14K gold shall not be less than 585 ‰; The gold content of 9K GOLD is not less than 375 ‰
    the National Standardization Administration has published the No. 1 amendment to gb11887-2012 regulations on the purity and nomenclature of precious metals in jewellery, which came into effect on May 4, 2016. In the future, even gold ornaments with a purity of 999.0 ‰ can only be labeled as "full gold", rather than "thousand full gold".

  2. Gold is divided into thousands of gold and thousands of gold. What is written in four nines is thousands of gold, and what is not written is thousands of gold. The purity has not reached 999, so it is not written.
