The purest gold is 24K, which means the gold content is 99.99%. No 100%. That's why it's called "gold is not enough"

If you want to collect gold and silver ornaments, you can go to large gold and silver shops such as Edcom, Claudius Gem Palace and Liu Fu Jewelry. (There are chain stores all over the country) In addition, you can go to gold shops in various cities. Note that large gold and silver collections will have gem identification certificates.
