I lately needed to have it resized as much as a dimension 6.5 and it nonetheless weighs 6.18 grams.
This was all performed on the authentic place of buy.
This final resize is a foul job as there’s a divot and you may see the place it was resized, additionally an emerald has been chipped. It’s a gold band that’s (was) pretty thick all the way in which round with stones solely on the highest.
How does the change in weight have an effect on my authentic appraisal if I have been to resell the ring?
I am fairly disheartened by the dangerous resize job and no change in gold weight, is that standard?
Thanks upfront for any recommendation you can provide me. 🙂
Reply: G’day and lots of thanks to your query.
Now the very first thing is you did not point out WHAT QUALITY of Gold the Ring was constituted of? If it was made in 9ct or 12 kt – it will have a really completely different worth than a hoop made in 18ct or 22okay for instance.
Nonetheless, on this case – the ring solely weighed 6.7 grams to begin with and was later weighed once more as being 6.18 grams. This can be a distinction of simply zero.52 grams (simply over half of 1 gram).
Assuming center floor at round 12 or 14 karat – the distinction within the gold high quality is minimal. We calculate it like this…
One ounce of PURE gold roughly equals 32 grams (pure gold being calculated as 24 carat). Oh and BTW – if you happen to see I’m switching between ct or kt (carats and karats) please learn my earlier articles on the Jewellery Appraisal Heart regarding gold high quality right here.
So we will calculate gold (listed in the present day) as being US$930 per ounce – so we divide that determine by the 32 grams as a way to see what one gram is price. That’s 930 / 32 = 29.0625 per gram.
