Can a 9ct gold ring be resized?

Yes. 9ct gold is worked by any bench jeweller, and we resize free for as long as you own the ring.

Is 9ct gold hard wearing?

Its surface sits at Mohs 3.5. For comparison, airborne dust contains quartz at Mohs 7, which is why anything below that picks up fine scratches from ordinary wear. This is well below it, so expect marks. They polish out.

Is 9ct gold hallmarked?

Yes, at the Birmingham Assay Office. Gold over 1g and platinum over 0.5g must legally carry a UK hallmark, and ours do.

How heavy is a 9ct gold ring?

11.2 grams per cubic centimetre. Titanium is the lightest thing we make at 4.5 and platinum the heaviest at 21.4, so this sits in the middle of the range.

Is 9ct gold safe for sensitive skin?

Not always. Some white gold alloys contain nickel, which is the usual cause of a reaction. If jewellery has irritated your skin before, choose titanium, zirconium, platinum or palladium.

HallmarkedBirmingham

37.5% gold against 18ct's 75%, so roughly half the metal cost in a year when bullion set an all time record. It is also the harder alloy of the two, which matters more on a ring worn daily than the carat number does. Fully hallmarked, fully resizable, and a British standard that has been sold here for over a century.

Honestly

All gold is soft. At Mohs 3.5 this will pick up more marks in a year than zirconium will in ten. That is normal and it polishes out.
