Gold Alloys

The most common way to describe the purity of the gold is through the term ‘karat‘. The term was first used as a form of weight, however, nowadays people use it to describe the purity of the gold.

When dealing with gold in karat, we simply use a number that is followed by the letter K: 9K,12K,18K,24K Gold. If the gold is completely pure it is described as 24K gold. In most countries, however, 99% pureness is already enough for the gold to be considered as 24K.

To go further, 12K Gold translates to an item that has 50% of pure gold inside it. Other half is composed of other metals, such as silver.

All in all, when you want to know the purity of gold in your items, you should divide the karat value of your gold by 24 and multiply it by 100. The end result is the % of purity of your gold. With that simple formula, you can quickly find out the real value of your golden possessions.
