Do gold weighing scales weigh different to post office scales?

Question

sold ring on ebay it wieghed 10grams at post office without packageing the buyer is saying it is only 6gram on her scales

Answer 1

unless both sets of scales have been calibrated using the same approved weights differences can be quite varying.I would at a guess trust the post office more than a personal scale simply because the post office will be regulated by the local  weights and measures office

Answer 2

Here is a web site that explains the weighing of Gold

Why don't you decide after reading it

I think that there is a difference

Answer 3

10 grams seems very heavy for a gold ring.

You need to be very careful with the Post Office as well. Someone in the sorting office switched some perfume I sent to my mum, with some counterfit junk from Hong Kong.
