HallmarkedBirmingham

A channel machined into zirconium or titanium and filled with solid 18ct gold or platinum. You get real precious metal on the face of the ring, hallmarked, at roughly a third of what the same ring costs in solid gold. It is the honest middle: not gold plated, not gold coloured, actually gold.

Right for

  • Wanting gold without a gold budget
  • Mixing metals with a partner's ring
  • A ring with a visible centre line

Wrong for

  • Anyone who wants scrap metal value
  • Resizing

Honestly

The inlay is a few millimetres of gold, not a gold ring. We say the weight on every product page so you know exactly what you are buying.

Precious inlay questions

Can a precious inlay ring be resized?
No. Precious inlay cannot be stretched or cut and rejoined the way precious metals can, and anyone claiming otherwise is describing a replacement. We replace free for life instead, which is the same outcome stated honestly.
Is precious inlay hard wearing?
Its surface sits at Mohs 8.5. For comparison, airborne dust contains quartz at Mohs 7, which is why anything below that picks up fine scratches from ordinary wear. This is comfortably above that line.
Is precious inlay 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 precious inlay ring?
7.2 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 precious inlay safe for sensitive skin?
Yes. It contains no nickel, which is the metal that causes almost all jewellery reactions.
