Did you know?
Out of the entire top layer of earth crust, you will only find 3.5 parts of pure gold out of 1 billion parts.
The karatage numbers gives you a precise indication of the gold composition.
24kt gold is 99.99% pure gold.
18kt is 75% gold and added metals such as copper, silver, and zinc. It is also presented as 18 parts gold and 6 parts of other metals. In Europe, they mark 18kt jewelry “750” which means 75% of pure gold.
14kt gold has 58.3% of pure gold, which means it has 14 parts of pure gold and 10 parts of other metals.
Of all metals, pure gold is the most ductile, which means that it can be transformed into various shapes and hold onto these shapes. Picture this: you could make a 80km/ 50 miles gold wire thread out of 31 grams of pure gold.
