What does 18K gold mean?

18K gold is 75% pure gold. The "18" means 18 of 24 parts are gold, and the other 6 parts (25%) are metals such as copper or silver. These added metals make 18K gold harder than 24K gold, so it holds its shape in rings, bracelets and chains you wear daily.

The trade-off is gold content. 18K pieces cost less per gram than 22K pieces, but they hold less gold and fetch a lower resale value per gram. Check for the Bureau of Indian Standards (BIS) hallmark 750, which confirms 75% purity.

Choose 18K for durability and a lower price per gram. Bajaj Finance accepts 18-22 karat jewellery for a gold loan, so 18K pieces qualify.

Significance of 18 Karat gold

Because it has 75% pure gold, it has a beautiful shine that immediately stands out, yet it remains strong enough for everyday use. This combination makes it a favourite for rings, earrings, necklaces, and even heirloom pieces that you want to pass down. You get elegance without worrying too much about scratches or bends. When you pick 18 carat gold, you choose something that blends sophistication with long-lasting quality. It is perfect for anyone who wants jewellery that stays stunning for years while holding sentimental and financial value.


How to check purity for 18 k gold?

Before buying any 18K gold jewellery, it helps to know how to check if it is genuinely 18K. Here are some easy ways to do that:

  • Look for a hallmark: Check for marks like 18K or 750, which show that the piece has 75% pure gold.
  • Get it tested professionally: A certified jeweller can test your gold using acid testing, electronic machines, or XRF analysis for accurate results.
  • Do a quick visual check: Pure gold has a richer yellow tone. Though not fully reliable, checking the colour and finish can give you an idea.
  • Ask for a certificate: Reputable jewellery sellers provide purity certificates to confirm authenticity.

These simple checks help you buy confidently and ensure your 18K gold truly holds the value you expect.

Impact of 18 karat gold rate on gold loan

The rate of 18 karat gold plays a big role in how much loan amount you can get. Since lenders calculate your loan value based on the purity and current market rate of your gold, a higher 18K gold rate means you may qualify for a higher loan amount. When the rate dips, the eligible amount may reduce. Keeping an eye on daily prices helps you plan your gold loan smartly and borrow at the right time. 


Pro tip: Manage planned to urgent expenses with ease. Check your gold loan eligibility now and make your gold work for your needs.


Please note: We also do not simply use today's headline rate. As per RBI, we use whichever is lower between the previous day's closing price or the 30-day average closing price published by IBJA or a SEBI-regulated commodity exchange. This protects you from a sudden price spike inflating things unrealistically. You can pledge your 18-22 karat gold jewellery or ornaments, or gold coins up to 24 karat purity as collateral for our gold loan offering. 

The maximum LTV eligible for a loan depends on the loan amount and cannot be more than the limits given. To know more, click here.
