Different Types of Gold Karats

For centuries, gold has been treasured due to its natural beauty, radiance and versatility. These qualities make it the most important metal in jewellery making. When you buy gold jewellery, there’s usually a choice between different kinds of gold colours, plating options and gold karats. The first thing you should look at is the karat.

You can see what karat gold jewellery is by looking for the karat mark, usually indicated with a “k”. The karat mark will tell you how much gold content the jewellery has. You should also look for the manufacturer’s trademark next to the karat mark to assure that the karat mark is accurate.

Guide to Gold Karats

Gold is divided into 24 parts, with each single unit called a karat. The higher the karat, the purer the gold:

  • 24 karat – 99.5% pure gold and above
  • 22 karat- 91.7 % gold
  • 18 karat – 75.0 % gold
  • 14 karat – 58.3 % gold
  • 12 karat – 50.0 % gold
  • 10 karat – 41.7 % gold

Higher purity gold is more popular with Asian and Indian jewellery while 14k to 18k gold is more widely used in western countries. As purity decreases, gold jewellery gets heavier and harder.

24k Gold

24 karat gold means 24 out of 24 parts are gold. Remember that this is the purest form of gold and that any dealer that claims to have 25k or 26k gold is being deceptive. Pure gold has a distinct bright yellow colour. As there is no higher form of gold, it is naturally the most expensive. Coins and bars are mostly bought of 24K gold purity as an investment. It is also used in electronic and medical devices.

However, it’s unusual to find 24k gold in jewellery. This is because pure gold is a soft metal. While it’s highly resistant to rust, tarnishing and corrosion, pure gold is just too pliable for regular forms of jewellery. Instead, gold jewellery is alloyed with other metals to increase its strength and durability.

22k Gold

22-karat gold jewellery has 22 parts gold with the other 2 parts made up of other metals. This kind of gold is commonly used in jewellery making. The addition of other metals like silver, zinc and nickel makes the gold harder, thereby making the jewellery durable. 22kgold is great for plain gold jewellery and best for naturally enamelled jewellery.

However, it isn’t preferable for heavily studded and diamond jewellery. As diamond is a precious material, it requires a metal that can strongly hold it and ensure it doesn’t fall off. 22k gold is still too soft to hold onto gemstones reliably. 22k gold is more commonly used in Asian and Indian jewellery than elsewhere, but can still popular around the world.

18k Gold

18-karat gold is 75 per cent gold mixed with 25 per cent of other metals. Studded gold jewellery and other diamond jewellery is often made in 18K gold. This kind of gold is not as costly compared to 24K and 22K, however it has a duller colour. 18K gold can be stamped with 18K, 18Kt, 18k or a variation similar to these or by 750, 0.75 or a stamp similar to these, symbolising that the jewellery contains 75 per cent gold.
