International Gold Karat
Gold is a precious metal that has been used for centuries to create jewelry, coins, and other objects. The purity of gold is measured in karats, with 24 karats being pure gold. However, pure gold is too soft for most practical applications, so it is alloyed with other metals to make it harder and more durable.
The international standard for gold karatage was established in 1907 by the International Organization for Standardization (ISO). The ISO standard defines the following gold karatages:
* 24 karats: 99.9% pure gold
* 22 karats: 91.6% pure gold
* 18 karats: 75% pure gold
* 14 karats: 58.3% pure gold
* 10 karats: 41.7% pure gold
Gold of different karats has different properties. For example, 24 karat gold is very soft and malleable, while 10 karat gold is harder and more durable. The karatage of gold also affects its color. 24 karat gold is a deep yellow color, while lower karat golds are lighter in color.
The karatage of gold is an important factor to consider when purchasing jewelry. The higher the karatage, the more pure the gold and the softer it will be. Lower karat golds are harder and more durable, but they also contain more alloy metals. The karatage of gold that is right for you will depend on your personal preferences and the type of jewelry you are purchasing.
