With a composition of 75% pure gold and 25% other metals like silver, copper, or zinc, it strikes a balance between purity and strength. This type of gold is admired for its ability to hold intricate designs, making it a preferred choice for crafting detailed and ornate jewellery pieces. Its slightly lower gold content compared to 24-carat gold enhances its resilience, making it ideal for everyday wear while retaining its inherent beauty and charm.

Unlike 24-carat gold, 18-carat gold contains a lower proportion of pure gold, making it more robust and suitable for crafting intricate jewellery pieces.

  • Use a magnifying glass: Inspect the gold for marks indicating purity.
  • Visual examination: Look for any discolouration or tarnishing, which might suggest impurities.
  • Magnetic test: Real gold is not magnetic, so a magnet can help distinguish it from other metals.
  • Nitric acid test: This test uses nitric acid to assess gold, but it is best done by a professional due to the use of chemicals.

To sum up, verifying the purity of 18-carat gold jewellery before purchase or sale is essential. 18-carat gold contains 75% pure gold, and its purity can be confirmed by checking for the BIS hallmark on the jewellery. Alternatively, you can conduct an acid test or use an electronic gold tester.

Frequently asked questions

Which is better, 18K or 22K gold?

Choosing between 18K and 22K gold depends on your needs. 18K gold offers 75% purity with added strength, making it ideal for everyday jewellery. 22K gold is 91.6% pure, providing a richer gold appearance but is softer and more prone to wear. For durable, frequently worn pieces, 18K gold is better. For more traditional, less-worn items, 22K gold is preferred due to its higher purity and luster.

Is 18 carat gold purity 90%?

No, 18 carat gold purity is not 90%. 18 carat gold purity means the gold is 75% pure, with the remaining 25% made up of other metals like copper, silver, or zinc. This combination increases the gold’s strength and durability, making 18k purity gold ideal for everyday jewellery. If you are looking for 90% purity, you might consider 21.6 karat gold instead.

What is 18K gold purity?

18K gold purity means the gold is 75% pure, with 18 parts out of 24 being gold. The remaining 25% is composed of other metals like copper, silver, or zinc, which provide additional strength and durability. This balance makes 18k purity gold a popular choice for jewellery, offering a good mix of purity and robustness, suitable for everyday wear while retaining a significant amount of gold content.

How does 18 carat gold purity percentage affect gold Rate?

The 18 carat gold purity percentage directly affects the gold rate. 18K gold has 75% purity, meaning it contains less pure gold compared to higher karat gold like 22K, which is 91.6% pure. Consequently, 18K gold is generally cheaper than 22K gold due to its lower gold content. The addition of other metals also impacts the gold rate in India, making 18K gold a more affordable option for jewellery while still maintaining a substantial gold presence.

Are interest rates affected by 18K gold purity?

Interest rates on gold loans are generally not directly affected by 18K gold purity. Lenders primarily consider the overall value of the gold and market conditions when determining interest rates. However, since 18K gold contains 75% pure gold, its valuation will be lower than higher-purity gold like 22K or 24K. This lower valuation may influence the loan amount you can secure, but the interest rate itself remains influenced by broader financial factors.
