The actual gold price is defined per gram or per 10 gram by exchanges for respective purity levels. This is the amount you pay for the weight of the gold you are buying. Making and wastage charges are calculated separately for every piece of jewellery. Making charges usually range from 3-25% of the gold price for mass machine-made jewellery. Wastage charges range anywhere between 5-7% of the amount of gold. However, most jewellers show only the making charges on the invoice, and it is inclusive of the wastage charges.
