24K Gold vs. 18K Gold: What’s The Difference? 6 Facts

24K Gold: What Is It?

The purity of 24 karat gold is very high. Sometimes, people call it “non-alloyed.” It only has gold in it—not zinc, silver, palladium, copper, nickel, or any other metal.

The most pure gold is 24K gold. It is still the softest, though. 24K gold is easy to scratch and bend. Because of this, it can’t be used every day. If you want to buy an engagement ring or other gold jewellery, 24K is the safest option.

Difference in Appearance

24 karat gold is always a bright yellow colour that stands out. Because 18-karat gold is an alloy, which means that it is a metal that has been mixed with other metals, it can have different colours.

Rose gold, which is a mix of gold and copper, and white gold are two common types of coloured 18-karat gold (usually nickel and gold).

Uses and Applications

Aside from 14k and 10k gold, 18k gold is also often used to make jewelry. Even though 18-karat gold jewellery isn’t as resistant to scratches and other marks as 14-karat gold and lower, it’s often chosen over pure 24-karat gold, which is expensive and easy to damage because it’s so soft.

These gold items were “minted,” which means they were made in a factory that makes coins, bars, and bullion from gold and other metals.

Like some other countries, the United States has laws that say how pure something, like a gold bar, must be. The standard is 99.9% purity.

Both 18k and 24k gold are used in decorative gilding techniques such as gold leafing and plating.

When decorating, 22 karat gold and better is easier to work with because it is easier to make thin sheets of purer gold.

Some electronics and medical tools are made with 24-karat gold. For example, children who keep getting ear infections might get gold tympanostomy tubes to let more air into the middle ear.


Gold is both heavy and soft because of the way its atoms are arranged. Because pure gold is so flexible, one ounce of it can be hammered into a very thin, 300-foot-square sheet that can be used to gild.

Overall, neither type of gold needs much care, but jewellery made of 24 karat gold shouldn’t be worn every day. Both can be damaged by bleach, but 24 karat gold is more likely to do so.

Other Terms

A karat, which is also called a “carat,” is a way to measure the purity and quality of gold. The purest gold is 24 karats. The higher the karat rating, the less the gold has been mixed with other metals, like silver or copper, to make a gold alloy.
