A ring with a stone has two different materials in one object. We buy the gold. The stone is not converted into a gold price.
Why the kitchen weight misleads
The gross weight includes the gem, the setting and sometimes a hollow gallery. Payable weight is what is left once those parts are out of the figure. A heavy-looking cluster ring can carry less gold than a plain band that feels lighter.
What we do with the stones
Diamonds and coloured stones can be removed and returned to you. We do not automatically buy them as part of a gold offer, and we do not quote a diamond price unless that has been agreed as a separate assessment. If you want the piece kept intact, tell us before any stone is taken out. Intact pieces that cannot be weighed as gold alone may simply be unsuitable for a scrap offer.
Hallmark versus setting
A 750 mark on the shank describes the shank alloy, not the stone and not the total object. White gold is still gold alloy. It is not “less real”, but it can be confused with silver or platinum until it is tested. We test rather than guess from colour.
