This type of gold is also referred to as 18K gold, as it contains 18 parts gold out of a total of 24 parts.
The Science Behind Gold Purity
Gold purity is measured using the karat system, where pure gold is defined as 24 karats. The breakdown is as follows:
– 24K Gold: 99.9% pure gold, considered the highest quality.
– 18K Gold (Au750): 75% gold and 25% other metals, offering good durability and value.
– 14K Gold (Au585): 58.5% gold, commonly used for everyday jewelry due to its affordability.
– 10K Gold (Au417): 41.7% gold, often used in lower-cost options.
The other metals mixed with gold can enhance strength and alter the color of the alloy, resulting in different types of gold like white gold or rose gold.
