Why 23-carat gold is special in India

Gold is highly durable. It does not rust, corrode, or react to most acids, which is why gold jewellery can last for generations. In India, gold also carries deep cultural value as part of traditions, festivals, and ceremonies. 23 karat gold has a purity of 95.83%. It is very close to pure gold while being slightly firmer than 24 karat gold, which makes it suitable for special jewellery pieces.

Understanding the unique properties and cultural importance of 23-carat gold helps you make better decisions, whether you are buying it for rituals, celebrations, or investment purposes.


How to check 23 carat gold purity

Understanding gold purity helps you verify authenticity and value before you buy, sell, or invest. Consider these methods:


  1. BIS hallmark: The Bureau of Indian Standards (BIS) hallmark is a reliable purity indicator. It is stamped on the gold item and confirms it meets India's purity standards
  2. Magnifying glass: Look for small engravings that show the purity level. A 23 karat piece should carry a "23K" or "958" mark
  3. Colour and shine: Genuine 23 karat gold has a rich yellow colour and an even shine. Dullness or colour changes can suggest impurities
  4. Magnetic test: Gold is not magnetic. If your piece reacts to a magnet, it may contain other metals or have lower purity
  5. Professional assessment: A certified jeweller or gold assayer can use specialised tools to give an accurate purity reading

Checking hallmarks, appearance, and expert opinion together gives you the most reliable result. Knowing your gold's purity helps you judge its value and get a fair deal, whether you buy it for a special occasion or as an investment.

Please note: We also do not simply use today's headline rate. As per RBI guidelines, 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.
