The receipt tells you what you paid for a finished necklace. An estimate of its gold content answers a different question. Keep both numbers, with labels that explain what they represent.
When reviewing a purchase:
- Find the metal weight and purity on the invoice.
- Separate any listed making charges, stone charges and taxes.
- Keep the total purchase amount as the historical price paid.
- Check what a current per-gram rate actually represents.
- Keep an estimated metal value separate from any written buyer's offer.
- Ask a buyer to explain the weight, purity and deductions used in its quote.
Making charges relate to creating the finished piece. Their treatment in a later sale depends on the buyer and transaction; do not assume that multiplying weight by a gold rate reproduces your receipt total. The World Gold Council's Indian jewellery market research discusses making charges within jewellery pricing.
For a stone-set necklace, gross weight is another detail to check. A calculation that treats the entire piece as gold can give a misleading result.
Your records become more useful when “purchase price,” “estimated gold value” and “buyer quote” remain distinct. Store the invoice with the piece so the original breakdown is available whenever you revisit it.
