Gold Necklace Went From 66g to 61g: Check Records Before Blaming Wear

Using 66 g and 61 g as an example, the difference is 5 g, or roughly 7.6% of the starting weight. If the original record says more than 66 g, use its exact number when calculating the actual difference. That is too large to explain casually, but the first step is not to invent a “normal wear rate.” The first step is to prove that both weights refer to the same complete item.

Check whether the two weights are comparable

  • Did the original 66g record include a pendant, clasp, tag, beads, small accessories or packaging?
  • Is the current weighing of the same necklace, with the same pendant and clasp attached?
  • Was the necklace repaired, shortened, polished, reshaped or exchanged at any store?
  • Were both weighings done on calibrated jewellery scales, with the result printed or written?

If the seller or repair shop polished, soldered or replaced parts, ask for its service record and weight-before/weight-after record. If the dispute is about quality or shortage, the 2024 Consumer Rights Protection Law Implementation Regulation provides a route for complaint handling and, where needed, quality appraisal. The National 12315 complaint notice is a practical market-regulation complaint channel.

Keep the comparison as a dated record: original documented weight, the complete item weighed now, any components missing or removed, scale reading and the person who performed the weighing. Taking photographs on the same scale helps document the process, but does not by itself establish the scale’s accuracy or prove who caused a difference.

What to ask for

  1. A written reweighing record from the seller or another jeweller.
  2. Copies of purchase, repair, cleaning and polishing records.
  3. A statement on whether any component was replaced or removed.
  4. Official or qualified testing if the parties cannot agree on weight or purity.

The answer is not “normal loss” or “definitely fraud” yet. It is: 5g is a material difference, so compare records, confirm the same complete object, and use formal testing or complaint channels if the explanation is not documented.
