Jewelry Engraving: Fonts, Depth and What Lasts

925 sterling silver jewellery, set with lab grown diamonds and made in our own Shenzhen workshop.

The engraving comes back illegible after three years and the assumption is that the wrong method was used. In most cases the method was fine and the specification was not: the letters were cut too small and too shallow for the surface, so ordinary polishing softened them into a blur. Engraving is limited by geometry rather than by technique, and the two numbers that decide whether a mark survives — letter height and cut depth — are set at the order stage.

What actually decides whether engraving lasts?

Depth first, then letter size, then placement.

Every polishing removes a thin layer of metal, and a shallow cut loses a meaningful share of its depth each time. A mark cut to at least 0.15 mm survives years of ordinary polishing; one cut to 0.05 mm looks identical on delivery and is soft within a season. Letter size works the same way: below roughly 3 mm, lettering stops reading as text at normal viewing distance and starts reading as texture, regardless of how deep it was cut.

Placement is the third variable, because a mark on a high-wear surface loses material faster than the same mark on a protected one.

Hand, laser and machine engraving compared

Three methods, and the honest differences between them.

Method	How it cuts	Best for	Limitation
Hand engraving	Cut with a graver, by hand	Script, ornamental work, curved surfaces	Cost and time; depends on the engraver
Laser engraving	Vaporised by a focused beam	Small text, logos, repeatability	Depth depends on settings; can look shallow if hurried
Machine or rotary	Mechanically cut to a pattern	Straight text, repeat orders	Less suited to script and fine detail

The common belief that laser engraving is inferior is a specification question rather than a method question: a laser cut to 0.15 mm depth and a graver cut to the same depth behave similarly in wear. What differs is how the mark looks at close range, since a hand cut has varying depth and a laser cut is uniform.

Fonts and what each surface can carry

Font weight should be chosen against the finish, not against preference alone.

A light script reads beautifully on a matte surface and can disappear on a highly polished one, because the polished surface reflects light across the thin strokes. A heavy block font cuts clearly but crowds a small disc, and on a curved surface it distorts at the edges. The practical approach is to choose a medium-weight font for polished metal and allow a lighter one only where the surface is matte and the letters are at least 4 mm.

Serif faces read better than sans-serif at small sizes because the contrast between thick and thin strokes survives cutting. All-capital block lettering is the most durable of all, for the same reason.

How much room a mark needs

Four formats, and the surface each requires.

Mark	Minimum letter height	Usable width	Best placement
Single initial	3 mm	6–8 mm	Front centre, or beside a stone
Three initials	3.5–4 mm	14–18 mm	Front or reverse of a disc
Date, numeric	3 mm	12–15 mm	Reverse face, or vertical on a band
Short name	4 mm	22–26 mm	Tag, bar or disc of 20 mm and up

Curved surfaces reduce the usable area further, because a mark wrapped around a cylinder distorts at the edges. On a band, that means keeping text within the central third of the visible width. The formats and their constraints for pendants are set out in our notes on personalised silver pendants.

Where to put the mark

Front, reverse or inside, and the trade each makes.

A mark on the front is visible and collects polishing wear. A mark on the reverse or the inside of a band is protected and hidden when worn, which is why dates, coordinates and private messages belong there. On a ring, the inside of the band is the standard location and is also the least disturbed surface, since it contacts the finger rather than the world. On a pendant, the reverse of a disc is the equivalent.

Placement should be referenced to a fixed feature — the bail on a pendant, the hallmark on a band — rather than to the drawing, because the drawing has no top once the piece hangs or sits on a finger.

What can and cannot be corrected

Three outcomes, depending on how much metal remains.

A faded mark can usually be re-cut, provided the metal has not been thinned by previous polishing; the engraver deepens the existing lines rather than cutting new ones. A misspelling can be corrected if the error is small and the surrounding surface allows the letters to be re-spaced, but the corrected area usually shows unless the whole mark is re-cut deeper. A mark on a piece that has been polished repeatedly may have no metal left to cut, in which case the options are to accept it or to replace the surface, which for a band means a new band.

This is why spelling is the one detail worth checking twice on a proof: it is the only error with no clean remedy.

Engraving on plated and finished pieces

The cut goes through the coating, and that has to be expected.

Engraving a rhodium-plated piece cuts through the plating and exposes the alloy beneath, which shows as a slightly warmer line inside the letters. That is an aesthetic effect rather than a defect, and it can be reduced by engraving before plating where the production sequence allows. On anodised or oxidised finishes the same applies: the cut removes the surface treatment, and the contrast is permanent.

Where the colour of the mark matters, the sequence should be specified: engrave first, then finish, so the mark carries the same surface as the rest of the piece.

Specifying engraving on an order

Six lines that remove the guesswork.

The exact wording and case. Letter height in millimetres. Engraving method and depth. Placement, referenced to a fixed feature. Font or a reference image of it. And the proof approval step, including who signs it off. Add whether the piece will be plated and in what sequence, and the specification is complete.

With those agreed, engraving is a predictable operation rather than a hope that the result looks as imagined.

FAQ

Laser or hand engraving: which is better?

Neither is better in durability terms; both depend on how deep the cut is. A laser mark cut to 0.15 mm behaves like a hand-cut mark at the same depth. The visible difference is character: hand engraving has varying depth and suits script, while laser cutting is uniform and suits small repeatable text.

What can be engraved on jewelry?

Initials, dates, coordinates, short names and symbols. Allow about 3 mm of letter height and at least 0.15 mm of depth for a mark that survives polishing. Full names need a surface of roughly 20 mm, and curved surfaces reduce the usable area because text distorts at the edges.

Will engraving wear off?

It fades rather than disappears. Every polish removes a thin layer of metal, so repeated polishing softens the edges of the letters over years. Marks cut to 0.15 mm depth stay readable well beyond that, and most loss can be corrected by re-cutting rather than replacing the piece.

Can a mistake be corrected after engraving?

Sometimes. A faded mark can be re-cut if enough metal remains. A misspelling can be corrected only if the surrounding surface allows re-spacing, and the correction usually shows unless the whole mark is deepened. On a repeatedly polished piece there may be no metal left to cut, which is why spelling is checked twice on the proof.
