A clear, no-jargon breakdown of how your old gold value is calculated at Londe Jewellers — with worked examples for 10g, 20g, 50g and 100g of 22K and 24K gold.
Before you walk into any showroom in Nagpur, you should know — to the rupee — what your old gold is worth that day. Most exchange disappointments happen because customers cannot do the math themselves and rely entirely on the jeweller's number. This guide gives you the formula, four worked examples, and the live rate to plug in.
Exchange Value = Net Gold Weight × Today's Per-Gram Rate × Purity Factor
At Londe Jewellers there is no fourth term for deduction or wastage on 22K and 24K. The number above is what we credit. Most other Nagpur jewellers add a fourth term: × (1 minus deduction percentage), which silently subtracts 5 to 20 percent of your value.
Net gold weight is your jewellery weight minus any stones (diamonds, kundan, pearls). The purity factor is 91.6% for 22K, 99.9% for 24K, 75% for 18K, etc.
The Londe Jewellers prevailing rate is published on our live gold rate page and updated daily. The rate you see on the website is the same rate we credit at the counter — there is no separate sell rate. Most Nagpur jewellers run a Rs. 100 to Rs. 200 per gram spread between their buy and sell rates; that hidden margin does not exist at Londe.
