Ever held up a beautiful gold necklace, only to be left asking what “22K” or “18K” marked on it really refers to? You’re not alone. Caratage is more than a figure—it determines the purity, value, and strength of your gold. If you’re purchasing, selling, or just wondering, knowing how pure gold is can help you make better decisions. So, what is 20-carat gold, and how pure is it?

Gold purity is a determining feature in its value, durability, and overall appearance. Although 24-carat gold is purest, it’s also the softest—and therefore less easy to wear daily. Lower-carat gold, on the other hand, is strengthened by alloys with other metals but has less actual grams of gold. Where does 20-carat fall, then? Is it an intelligent option for jewellery? How does 20-carat rate against other forms of gold? No matter whether you want to buy, invest, or sell gold, its purity is what you should be aware of. Let’s learn everything you need to know about 20-carat gold and whether it is for you.

What You Should Know About Gold Purity in Carats

Gold purity is also weighed in carats, with 24-carat being the purest and that is literally 99.9% gold. Pure gold is very soft, so it’s usually alloyed with other metals to make it stronger. This is a brief rundown:

  • 24 Carat Gold – 99.9% gold (soft and prone to scratches)
  • 22 Carat Gold – 91.6% gold (most often used in jewellery)
  • 20 Carat Gold – 83.3% gold (a balance of purity and durability)
  • 18 Carat Gold – 75% gold (very strong and widely used in fine jewellery)
  • 14 Carat Gold – 58.5% gold (less expensive and scratch-proof)

What’s Inside 20 Carat Gold?

If 20-carat gold is not pure 100%, then what is the other 16.7% made of? Metals such as copper, silver, or palladium are added most often to make it more durable and to make it richer in color overall.

Why Choose 20 Carat Gold?

  1. Best of Both Worlds – Pure enough to be valuable but durable enough for everyday use.
  2. Ideal for Jewellery– Provides a rich yellow colour without being too soft or easily damaged.
  3. Holds Its Value – Greater gold content results in improved resale value if you ever choose to sell gold.
  4. Less Likely to Tarnish – In contrast to lower-carat gold, it stays bright longer.

20 Carat Gold vs Other Gold: Which One Is Best for You?

  • 24 Carat vs 20 Carat – If you need investment-grade pure gold, opt for 24-carat. But if you need gold for jewellery, 20-carat is the way to go.
  • 22 Carat vs 20 Carat – 22-carat gold is a tad purer but also softer, so 20-carat is a better option for detailed jewellery.
  • 18 Carat vs 20 Carat – If you consider durability, gold of 18 carats would be a better option. However, if you prefer additional gold content, continue with 20-carat.

Where is 20 Carat Gold Used?

  • Jewellery – Rings, necklaces, and bangles made of 20-carat gold are both stunning and durable.
  • Investment – As it has a high gold percentage, it’s a good investment choice.
  • Gold Coins and Collectibles – Some coins and commemorative pieces are crafted with 20-carat gold.

In a nutshell

20-carat gold offers the best balance of purity and strength, so it is perfect for jewelry lovers as well as investors. Whether you purchase or sell gold, being aware of its purity can help you make the appropriate decision.
