What Makes a Good Fingerprint Engraving | Tag A Paw
Share
We've been engraving for over 20 years. Fingerprints, paw prints, handwriting, signatures, full portraits, and far stranger things. We've watched the fingerprint jewellery market boom, flood with mass-produced lookalikes, and quietly disappoint a lot of customers six months after they bought.
This is a post about why some fingerprint engravings still look good a decade later, and why others fade in a few months. Both are sold as "engraved sterling silver." Both look fine in photos. Only one of them holds up.
If you're about to buy a fingerprint piece — your own, a gift, a memorial — this is what to look for.
The four things that matter
After this many years, it comes down to four things. Material, depth, detail, and the maker.
We'll take them in order.
1. The material underneath
Most fingerprint jewellery on the UK market is sterling silver. That's the legal minimum to call it sterling. What varies — wildly — is the thickness of the silver underneath the engraving.
The thinner the silver, the shallower the engraving can be. A 1mm sterling silver disc can only be engraved so deep before it weakens. A 1.7mm disc can take much deeper engraving without losing structural integrity. The same applies to rings — a thin band can't carry a deep fingerprint without bending.
Most off-the-shelf fingerprint pieces are 0.8mm to 1.2mm. Ours are thicker because the engraving needs the room. You'll feel the difference the moment you hold it.
When you're shopping, look for the thickness in the product spec. If it isn't listed, ask. A workshop that knows what it's doing will tell you.
2. Engraving depth
This is the one nobody talks about, and it's the one that decides whether the piece still looks like a fingerprint in five years' time.
There are two kinds of engraving sold under the same name:
- Surface etching. A shallow mark on the top of the metal. Looks crisp on day one. Wears smooth with daily contact — sleeves, skin, keys, soap, life. Within a year, it starts looking faded. After three, it can be nearly gone.
- Deep engraving. The print is cut substantially into the metal. The ridges have actual physical depth. The piece can be polished, rubbed, knocked around, and the engraving stays sharp.
A lot of mass-produced fingerprint jewellery is surface etched, even when the listing says "engraved." It's faster, cheaper, and the difference isn't obvious from a product photo.
Our fingerprint engravings are deep — 2.5D — meaning the engraving isn't just cut down, it has shape and dimension. The ridges of the print physically push into the metal, and the edges sit slightly proud, the way a real fingerprint would press into something soft.
It's why we can offer a lifetime guarantee on the engraving. We wouldn't if it weren't built to last that long.
3. The detail in the print itself
A good engraving captures three things from the source image:
- The overall pattern. The loops, whorls, or arches that make the print recognisable as a fingerprint
- The ridges. The individual lines that make it recognisable as this person's fingerprint
- The proportions. The way the print sits naturally on the surface — not stretched, not centred awkwardly
When a fingerprint engraving disappoints, it's usually because one of these is missing. The pattern is there but the ridges have been smoothed away. Or the ridges are there but the proportions look off. Or the print has been resized to fit a generic template and now looks like everyone else's.
We work with the original image — the actual photo, mould, paper print, or mortuary card you sent us. We don't run it through a generic template. The print on the finished piece is yours, scaled to the piece you chose, with the detail preserved.
This is also why we can work with imperfect images. We're not trying to fit a print into a system — we're engraving the print you've got, however it came in. We've written more about how to send us your fingerprint here.
4. The maker
This is the bit that's hardest to put on a product listing, but it shows up in the finished piece.
A lot of fingerprint jewellery in the UK is dropshipped — ordered online, made somewhere else, finished by people who never speak to the customer. The system works for low prices and quick turnaround. It doesn't work for getting the difficult cases right.
We do everything ourselves. Michael designs the pieces, cuts the silver, sets up the engraving, runs it, finishes it by hand. Andreea handles the customer side. The kids and the dog supervise.
That means when a difficult fingerprint comes in — a faint mortuary print, a phone photo taken in bad light, an old piece of inherited jewellery — there's a 20-year jeweller's eye looking at it, not a piece of software deciding whether to reject the order.
It also means we can be honest. If the source image really isn't usable, we'll tell you. We don't push orders we can't deliver on.
What "good" actually looks like
A good fingerprint engraving:
- Stays sharp after years of wear, not weeks
- Catches the light at the right angles — you can feel the ridges with a fingernail
- Looks like the specific print you sent us, not a generic version of a fingerprint
- Doesn't soften when polished — polishing should only make it cleaner, not flatter
- Comes with a guarantee the maker is willing to honour
A disappointing fingerprint engraving:
- Looks faded after a year of normal wear
- Can't be felt at all when you run a fingernail across it
- Looks like a stylised pattern more than a real print
- Comes with a 6 or 12-month warranty that quietly ends
- Was made by someone you never spoke to
If you're about to buy and you can only check one thing, check engraving depth. It's the difference between a piece you'll keep and a piece you'll replace.
The short version
Twenty years tells us the same lesson, over and over. Material thickness sets the ceiling. Engraving depth decides how long it lasts. Source detail decides whether it looks like the right person. And the maker decides whether anyone's actually looking at your specific piece.
If you'd like to see how we do it, our fingerprint collection is here. Each piece is designed in-house, deeply engraved, hand-finished, and guaranteed for life.
FAQ
How deep is your fingerprint engraving? Our engraving is 2.5D — meaning the print is cut substantially into the metal with dimensional shape, not just etched onto the surface. You can feel the ridges with a fingernail. It's why we can offer a lifetime guarantee on the engraving.
Does fingerprint engraving fade over time? Surface etching fades. Deep engraving doesn't — though the silver around it may polish brighter with wear, which actually makes the engraving more visible, not less.
Why is your fingerprint jewellery thicker than others? Deep engraving needs metal to cut into. Thinner pieces can only be etched superficially. We use a heavier gauge of sterling silver so the engraving has the room it needs to last.
Can you tell the difference between deep engraving and surface etching by looking? Sometimes, in good photos. The reliable test is to run a fingernail across the print — if you can feel the ridges, it's deep. If it feels smooth, it's surface.
Do you offer a guarantee on the engraving? Yes. Every fingerprint piece carries a lifetime guarantee on the engraving. If it ever fades in normal wear, we'll re-engrave it.
