Understanding 20 carat gold: Purity, uses, and significance

20 karat gold contains 20 parts pure gold and 4 parts other metals like silver, copper, or zinc, giving it a purity of 83.33%. This mix strikes a good balance between purity and strength, making it well-suited for intricate, durable jewellery designs. It is especially valued for traditional pieces where detail matters, though it is softer than lower-karat gold, so may not suit everyday wear as well. Checking for the 20 karat hallmark helps confirm authenticity.


What is the purity percentage of 20 carat gold?

Karat measures how pure gold is — the higher the carat, the more pure gold it contains. 20 karat gold works out to 83.33% pure gold, calculated by dividing 20 by 24. The remaining 16.67% consists of other metals that add strength. Knowing your gold's karat helps you understand its value, durability, and suitability for jewellery or investment.

Methods to check 20 carat purity

Testing gold purity involves using different simple techniques. While these methods give a basic idea, for accurate results, it is best to ask a certified jeweller or a professional gold assayer.


  • Use a magnifying glass: Look for purity marks on the gold.
  • Visual check: Check for any changes in colour or stains that could mean impurities.
  • Magnetic test: Gold does not react to magnets, so this helps distinguish it from other metals.
  • Nitric acid test: This involves using chemicals to test gold and should be done by a professional.

Confirming 20 karat gold's purity before you buy or sell it matters — check for the hallmark, or verify it through an acid test or electronic gold tester. Understanding your gold's purity helps you judge its value, whether you're buying it as an investment or a stylish piece.

How is the price of 20 karat gold jewellery determined?

The price of 20 karat gold jewellery depends on the current market rate for its purity, along with making charges and applicable taxes. To estimate it, check the applicable gold rate per gram and multiply it by your jewellery's weight, then add making charges and taxes. For a gold loan, remember that we do not use the day's displayed market rate directly — as per RBI guidelines, we use the lower of the previous day's closing price or the 30-day average closing price for your gold's specific purity, published by IBJA or a SEBI-regulated commodity exchange. With us, you can pledge 18-22 karat gold jewellery or ornaments, or gold coins up to 24 karat purity.
