Gold rate in India, 24K, 22K and 18K explained
The number before the K tells you how pure the gold is. 24K gold is 99.9% pure and is mostly bought as coins and bars. 22K gold is 91.6% pure and is the usual choice for jewellery, because the added metals make it stronger for daily wear. 18K gold is 75% pure and is common in diamond and fashion pieces. Higher purity means a higher price per gram, so compare rates of the same carat only.
