Price = weight × that carat’s rate + making charge + 3% GST. 10 g of 22K worth ₹1.37 lakh, with 12% making and 3% GST, comes to about ₹1.58 lakh.

22K is 91.6% gold. Multiply the 24K rate by 0.916 for a rough 22K rate. 18K is 75% gold.

Gold jewellery carries 3% GST, charged on both the gold value and the making charge.
