[final schedule comparison and selection guide]
Today's novel is a complete account of the purity of gold and its market name。
I. What is the purity of gold
Gold purity refers to the metal content of gold in jewellery or gold bars. Because pure gold (24k) is too soft to make complex jewellery directly, and even if it is able to do it, it is easily deformed, people add other metal elements (e. G. Silver, copper, zinc, etc.) to increase their hardness, strength and colour change, which creates gold of different purity and colours。
At present, there are two main purity labels in the market:
K gold: 24 copies of pure gold, 1k representing 1/24 gold content. Thousands of feet: pureness is expressed as a percentage of a thousand points, e. G. “999” represents 99. 9 per cent gold, i. E., “9999” represents 99. 99 per cent gold。
