Table of Content

Gold purity, measured in karats, indicates the amount of pure gold in a gold alloy. A higher karat value means a higher percentage of pure gold. For example, 24K gold is 99.9% pure, while 14K gold is 58.3% pure. The different types of gold karat affect purity,  gold's color, durability, and suitability for different uses.

Depending on the purity level, gold is classified into different karat types: 10k, 14k, 18k, 22k, and 24k. Below are explanations of the various types of gold karats:

24k Gold (999 Gold Purity)

24 karat gold is also known as 999 gold, also measured at 99.9%, making it the best available in the market. It contains negligible traces of other metals. As such, it is the purest form of gold available, characterised by its bright yellow colour. It is more expensive than other gold types due to its high purity. However, because it is relatively soft compared to lower karats, 24k gold is not ideal for regular jewellery, as it is prone to scratching and bending. As of May 7 2025, the 24-karat gold price in India is approximately ₹9,846 per gram. For 10 grams, the rate is about ₹98,460, and for 100 grams, it is around ₹9,84,600.

22k Gold (916 Gold Purity)

22 karat gold is also known as 916 gold that is 91.6% pure, making it among the best purities of gold readily available in the market, also being a durable and popular choice for jewellery. It contains 91.67% pure gold and 8.33% other metals such as copper, silver, or zinc, which help harden the metal, making it more durable for everyday wear.

Although 22k gold is frequently used for traditional jewellery, it may not be ideal for settings with heavy gemstones like diamonds, as the gold may not hold them securely. It's more commonly found in wedding bands and other occasional jewellery. The 22-karat gold price in India on May 7, 2025, is approximately ₹9,075 per gram. For 10 grams, it is around ₹90,750.

20k Gold (833 Gold Purity)
20 karat gold, also referred to as 833 gold, is made up of 83.3% pure gold, with the remaining 16.7% composed of various alloys, making it a good balance between purity and strength. Its higher gold content compared to 18k gold gives it a richer yellow hue, but it's still durable enough for everyday wear. 20k gold is often used in fine jewelry such as necklaces, bracelets, and earrings. It is slightly less expensive than 22k gold but offers more durability than 18k gold.

While 20k gold is generally suitable for daily wear, it may cause mild allergic reactions due to the presence of alloy metals like copper and nickel. As of May 7, 2025, the price of 20 karat gold in India is approximately ₹7,900 per gram and ₹79,000 for 10 grams.

18k Gold (750 Gold Purity)

18 karat gold is also known as 750 gold that is 75% pure, with the remaining 25% made up of alloys, offering a balance between purity and durability for everyday wear. The price of 18 karat gold is lower than 22k and 24k gold, and because of its strength and durability, it is commonly used in the creation of rings, watches, and other wearable accessories. Its vibrant yellow colour and relative durability make it a popular choice for engagement rings.

Since it contains more alloy metals like nickel, 18k gold may be more likely to cause allergic reactions than higher-purity gold such as 22k or 24k. As of May 7, 2025, the price of 18 karat gold in India is approximately ₹7,385 per gram and ₹73,850 for 10 grams.

14k Gold (583 Gold Purity)

14 karat gold is also known as 583 gold consisting of 58.3% pure gold and 41.7% of other alloys. The price of 14 karat gold is lower than 18k, 22k, and 24k gold, as it contains a higher proportion of non-gold metals. These metals, like copper, nickel, and silver, enhance the gold’s durability and prevent wear and tear, making it suitable for active or everyday jewellery.

14k gold is often used for pendants, lockets, and heavy-studded jewellery due to its strength and relatively affordable price. The price of 14-karat gold in India today, May 7, 2025, is approximately ₹5,744 per gram and ₹57,440 for 10 grams.

10k Gold (417 Gold Purity)

10k gold is 417 gold that is composed of 41.7% pure gold and 58.3% alloys, also considered among the best purities of gold readily available. The price of 10 karat gold is the least amongst its counterparts at approximately ₹3,480 per gram and ₹34,800 for 10 grams. It is the lowest purity of gold that can be sold as gold in many countries, such as the United States. Although it is strong and durable, its lower gold content makes it prone to discolouration and is generally less popular for jewellery, as it has a paler yellow tone.

10k gold is primarily used for simple jewellery items such as rings and chains but may not be suitable for those who prefer a higher gold content.

What Type of Gold is Mostly Used in Making Jewellery?

The most common gold used for jewellery is 22k gold, particularly in markets where gold purity is a significant factor, such as in India. However, 18k, 14k, and 10k gold are also commonly used, especially for designs requiring more durability for daily wear. While 24k gold is used for high-end products like gold bars and coins, it is less common in jewellery due to its softness.

Which Type of Gold is Ideal for Daily Use?

For daily wear, 18k or lower karat gold is ideal due to its strength and resistance to wear and tear. Gold with a higher percentage of alloys is more durable, making it suitable for regular use. On the other hand, 22k gold is better suited for occasional wear, like during special occasions or weddings, as it is relatively softer and may not withstand the rigors of everyday use.

When choosing the right gold for your needs, consider factors like the intended use of the item (jewellery, coin, bar) and your preferences for purity versus durability. Additionally, always check for proper certification and authenticity before purchasing any gold items.
