Although the names of red gold, rose gold and rose gold are interchangeable, the copper content of the three kinds of gold is actually different-the more copper, the heavier the red color. Because pure gold is golden yellow and pure copper is rose red. The common rose gold is 18K gold with a gold content of 75%. Because rose gold is a kind of gold alloy, the so-called "pure rose gold" is incorrect.
The rose gold with the highest gold content is a kind of 22K gold called "Crown Gold", which is a kind of gold for coinage. 18K red gold can be smelted from 25% copper and 75% gold. Typical 18K rose gold usually contains 75% gold, about 4% silver and 2 1% copper, showing a beautiful rose color. 14K (containing 58.33% gold and 4 1.67% copper) red gold is mostly found in the Middle East.
