Ring blanks

from £75incl. VAT · blank only, engraving quoted separately

A flat profile gives you a second option: outside, where people can read it. We will still steer you away from surface methods there, for the reason set out on the methods page.

Engraving faces

  • Inside the band

    44.5 × 3 mm usable · 8 mm reserved for the hallmark

    8 mm of the inner wall is reserved for the hallmark and stays clear of your text.

  • Outside the band

    52.5 × 2.6 mm usable

    A flat outer face holds a line, but it is the surface that meets everything.

Methods on this blank, and what fits

Hand engraving

+£65 · +5–8 working days · up to 35 characters per line at 2 mm

Machine engraving

+£25 · +2–3 working days · up to 47 characters per line at 1.5 mm

Laser engraving

+£18 · +1–2 working days · up to 71 characters per line at 0.8 mm

Surface treatment. Long wear — especially on the outside of a ring — will gradually make it fainter. We do not describe it as lasting for ever.

Diamond drag

+£30 · +2–3 working days · up to 71 characters per line at 1 mm

Surface treatment with almost no depth. It wears faster than the cut methods and is not suited to outer ring faces.
