Difference Between 14k and 18k Gold (With Table)

Jewellery made of pure gold is too soft to be used every day, so alloys and mixtures of metals are used instead. The soft and malleable nature of gold in its purest form makes it difficult to work with when making jewellery. Due to this, the only way to make pure gold hard is to mix it will alloy metals in different proportions. For this reason, the purity of gold must be determined by a scale.

There was a scale that could be used to determine the purity of the gold alloy when gold is mixed with alloy when gold is mixed with alloy metals in different percentages. This scale is known as the Karats, which indicates the purity percentage of a gold alloy.

14k vs 18k

The main difference between 14k and 18k gold is that it’s percentage 18k gold has a purity level of 75% (18/24) and 25% other metal alloys 14k gold has a purity level of 58% (14/24) and 42% other metal alloys. Because the alloys used in 14K gold change its colour from pure gold to a lighter tone, 18K gold has a rich yellow colour.

There are 14 parts gold in a karat of 14 karat gold, which consists of 58.3% gold and 41.7% alloy. Rings and other jewellery made of 14K gold have a rich, classic appearance, with the rich colour and classic gold finish that most customers desire. Although it is just over half gold, 14K was selected for an entirely different reason.

When you have a nickel allergy, you’re less likely to experience skin irritation when wearing jewellery made of 18K gold since it is almost pure.
