Ask before you post, always
You never have to commit to anything to start. Message us on WhatsApp or call, tell us roughly what you have, and send a few clear photos for a quick indicative figure. Nothing leaves your hands until you decide it should, and there is no obligation even then.
GoldPaid is a UK-wide postal gold and silver buying service. Wherever you are, you sell 18ct gold by post with a free tracked Royal Mail label. There is no shop to visit and no counter pressure.
What 18ct gold is
18ct gold carries the fineness mark 750. It is 75% pure gold, with the rest made up of other metals for strength and colour. It is the premium standard for fine British jewellery, engagement rings, quality wedding bands and better dress pieces are often 18ct. You may also see it stamped 18k, 18ct or .750.
Whatever the carat, GoldPaid pays for the confirmed gold content. 18ct items are weighed and XRF-assayed exactly like any other, a piece marked 750 is never paid at the wrong rate. For how the marks work, see the gold hallmark guide.
What 18ct gold we buy

Valued on fact, not estimate
Your valuation rests on three things we can measure. An XRF assay confirms the purity, a calibrated scale records the weight, and the live precious-metal rate on the day sets the price. It is all shown to you in writing first. XRF testing explained covers how the assay works.
Indicative 18ct rates are published on our gold calculator, last reviewed 4 August 2026. Those rates move with the live market and are a guide only; your firm offer follows the XRF assay of your specific items.
Postage and cover
Your parcel travels on Royal Mail Special Delivery, and Royal Mail cover may be available up to £2,500 depending on the postal method and cover level used. The label we send is Royal Mail Special Delivery Guaranteed: tracked end to end, signed for on delivery, and arranged with that compensation cover per parcel. If you believe your items are worth more, message us before posting. We will arrange the right approach, either extra cover or splitting the items across more than one parcel.

Common questions
Do you buy broken or unhallmarked 18ct gold?
Yes. Condition does not matter. We pay for the metal content, so broken, worn and single items are all welcome. Unhallmarked gold is fine too; the XRF assay confirms the carat for certain.
Is 18ct gold worth much more than 9ct?
Yes, 18ct is 75% pure against 9ct’s 37.5%, so gram for gram it is worth roughly twice as much in gold content. Even small 18ct pieces can carry real value. Your firm offer follows the XRF assay of your specific items.
What if I decline the offer?
Your items are returned to you free of charge by tracked, signed-for Royal Mail post. There is no fee for declining and no follow-up pressure.
Request a free prepaid Royal Mail label
Tell us where to send it. The label arrives by email, usually within about 30 minutes during working hours. Requesting one commits you to nothing: you get a written offer after the XRF assay, and if you decline, your items come back to you free.
