Global stock markets tumbled, with most falling into bear market territory as Chinese people celebrate the Lunar New Year. Investors' risk aversion was high, pushing the international gold price to break through $1,200 an ounce. Although China is on holiday, the Chinese are not idle. Taking advantage of the low price of gold, many Chinese snapped up gold jewellery during the Chinese New Year.

The US media CNN recently reported that China has entered an era of "crazy gold purchases". In just five years from 2010, the import volume of gold in mainland China has soared, with an increase of more than 700%. According to John LaForge, director of Wells Fargo's commodity group, 40% of the gold mined in the world each year goes to mainland China.

According to Hong Kong data, the total amount of gold imported by China was only more than 100 tons in 2010, but it has risen to the level of nearly 1,000 tons last year. CNN analyzed in the article that gold has flowed more into the pockets of the increasingly wealthy Chinese people. Chinese people mainly buy gold jewelry.

Although you are rich and rich, you can buy gold, but you can't be willful. What should I do if I buy gold that is not very pure? Let's take a look at the purity categories of gold and introduce several methods to identify the purity of gold for your reference:

What does "K" gold and "full gold" mean?

Internationally, people often use "K" to measure the content of gold or the purity of gold, and "K" is taken from the French Karat. 24K gold means pure gold, then 1K means 1/24, or 4.1666%, so 1K means that the gold content is 4.1666%. Then 18K gold means that the gold content is 18/24, which is 75%, and the remaining 25% is other metals.

In China, when it comes to the purity of gold, people may hear more about pure gold, such as thousand pure gold, ten thousand pure gold, one hundred thousand pure gold and so on. Gold with a purity of 99% can be called "pure gold", gold with a purity of 99.9% is called "thousand pure gold", gold with a purity of 99.99% is called "ten thousand pure gold", and gold with a purity of 99.999% can be called it "One hundred thousand pure gold", or "high-purity gold". Due to the defects of the smelting technology itself, 100% pure gold does not exist at all.

Now people buy more gold jewelry, and many businesses also use people's lack of gold knowledge to deceive or even deceive propaganda. According to the "Regulations and Nomenclature for the Purity of Precious Metals in Jewelry", the minimum purity of pure gold is 990, that is, the purity is not less than 990‰; the minimum value of pure gold is 999, that is, the purity is not less than 999‰. The provisions on the purity of gold in the national standard refer to the minimum value of purity.

Gold jewelry will have a mark on the purity of gold. For example, 18K gold is marked on the jewelry as "G18K", "Au750" or "Gold 750"; pure gold is marked on the jewelry as "G999", "Au999" or directly marked "Thousands of gold" three words.
