Difference Between 18K, 22K, and 24K Gold

Gold is an embodiment of luxury, elegance, and traditions. Nonetheless, when it comes to purchasing it, the terms such as 18K, 22K, and 24K appear. They can be confusing at first sight. Thus, how are these designations different from each other?

The thing is that these numbers determine the gold’s purity. The bigger its number, the purer the gold is. Nevertheless, besides the purity level, the gold becomes stronger but less resistant and expensive. In light of this, you should know the features before buying it.

What Is “Karat” When Talking About Gold?

It is important to define basic aspects of karat first of all.

The definition says that the term karat (K) is used for measuring the quantity of gold content. One hundred percent of gold is equal to 24 karats. Hence, the proportions will be as follows:

• 24K – 100% gold
• 22K – 91.6% gold
• 18K – 75% gold

Moreover, to increase durability, jewelers add metals, such as copper, silver, or zinc to the alloy.

What Is 24 Karat Gold?

The highest purity of gold comes from 24K gold.

Main Attributes:

• Purity level: 99.9%
• Color: Dark and shiny yellow
• Softness level: High
• Application: coins, bullions, investing

- Thus, if your target is to invest, it will be the best option.

What Is 22 Karat Gold?

22K gold is composed of a mixture of other metals. Consequently, it becomes stronger.

Main Attributes:

• Purity level: 91.6%
• Color: Yellow
• Strength: Medium
• Application: Jewelry

22K gold has become a preferred choice of Indian buyers during weddings due to its tradition. But it still remains quite soft;

- therefore, it doesn’t have the strength to keep gemstones.

What Is 18K Gold?

There is more alloy content in 18K gold, and hence the material has better durability.

Key Properties:

• Purity: 75%
• Color: Yellowish gold (can be also white gold or rose gold)
• Durability: Highly durable
