Method 1 – Finding the Right Ring at Home: Lay the ring flat, measure the inner diameter from inner edge to inner edge, and compare it to the chart.
Method 2 – Measuring with Your Finger: Wrap a thin strip of paper or a piece of string around your finger, mark where the ends meet, and measure the length. That is the circumference—divided by 3.14 gives the inner diameter. For a more accurate result, take several measurements and calculate the average.
Not sure? The kit includes pre-cut ring stencils that are true to the original. Try it on, specify the size when you upload it—only then will we engrave it.
Delivered free of charge by mail in 1–2 business days. Included in the kit:
LIINI Tip: The easiest way to take the impression is while your baby is sleeping. Two kids? Then take two impressions—the kit has space for them. Failed? We'll send you a new kit for free.
Does my baby already have fingerprints?
Yes—they begin to develop around the 22nd week of pregnancy and are fully formed by the time of birth.
At what point does the imprint become clearly visible?
It's different for every child. We recommend taking the measurement starting at 6 months. If it's not clearly visible yet, just wait: Your order is valid indefinitely, and you can upload the photo at any time later.
Will this hurt my child?
No. Taking the impression is completely painless—and it's easiest to do while your baby is sleeping.
Will the print be engraved at its original size?
We digitize it and laser-cut it on a 1:1 scale—adjusted to fit the size of the pendant or ring.
Is that real gold?
No—it's a high-quality 18-karat gold plating on 925 sterling silver, so it's costume jewelry. Solid gold of this size and quality would not be possible at our price.
Can I give this piece of jewelry as a gift?
We'd be happy to—just provide the desired shipping address when you place your order. The kit will then be sent directly to the recipient.
Polish with a soft, dry cloth. Take off your jewelry when washing your hands, showering, swimming, or exercising; apply perfume and lotion first, then put on your jewelry. Do not clean gold-plated rings with silver polish or treat them with an ultrasonic cleaner. It's best to store it in a jewelry box.
The kit is shipped free of charge from our warehouse in Switzerland and arrives in 1–2 business days. We'll ship your finished ring in a jewelry box, insured and with tracking —you'll be notified as soon as it's on its way.
Each ring is engraved just for you; you can adjust the size until the engraving is done. You can find details about returning personalized items in our Terms and Conditions. Support 7 days a week—including weekends.
LIINI was created in 2021 because having warm milk on the go was an unsolved problem. Today, more than 100,000 families trust us—and the jewelry that holds the tiniest hands. Developed in Switzerland, given as gifts by parents to parents. And if something isn’t working right: Our support team is still available even when others have already started their weekend.
No symbol from a catalog, no stamp: The signet ring features your child’s actual fingerprint —laser-engraved 1:1, just as you’d take it at home. A ring that exists in only one copy. For Mom, for Dad—or as a couple’s set with two prints. And every time you look at your hand, you’ll see a piece of a memory that isn’t captured in any photo booth.
Signet ring made of 925 sterling silver, available with 18k gold plating or rose gold plating upon request, in sizes 1 (16.5 mm), 2 (17.3 mm), and 3 (18.1 mm). Not sure? The kit includes full-size ring templates —try them on, specify the size when you upload the file, and only then will we engrave them. Comes in a high-quality jewelry box.
From click to chain: take the print at home, upload it via QR code – no appointment, nothing to post back.
Choose chain, material and engraving style – that is all you need at checkout. Within 1–2 working days the free fingerprint kit is in your letterbox: ink strips, instructions and your card with a personal QR code.
Press the finger gently onto the ink strip and transfer it to the card – works while sleeping too. Then scan the QR code and upload a photo of the card. Nothing to post, no appointment. Didn’t work out? We send a new kit free of charge.
We pick the best print, prepare it digitally and laser it 1:1 into the metal – in Switzerland and Germany. About 10–14 working days after your upload, your piece is with you in its jewellery box, insured and tracked.
Two children? Simply take two prints – the kit has room for both.
Do you already have another ring at home?
If you already have a good fitting ring, you can use that to determine the size.
Step 1: Prepare material
Step 2: Measure the existing ring
Lay the existing ring flat on a flat surface. Make sure that it does not deform or twist. Use the ruler or tape measure to measure the inside diameter of the ring. This is the distance from one inner edge to the opposite inner edge of the ring. Note the measurement in millimeters.
Step 3: Compare with our size chart
Now compare the measurement you noted with our size scale and choose the appropriate ring size.
If you don’t have a matching ring at home, you can easily determine your size with the following procedure.
Step 1: Prepare material
Step 2: Measure the circumference of the finger
Wrap the thin strip of paper or string around the finger you want to wear the ring on. Make sure the strip fits snugly, but not too tight or too loose. Use a pencil to mark the place where the strip or string overlaps.
Step 3: Check the size
To make sure that the determined ring size is correct, you can wrap the thin paper strip or string around your finger again and place the ring on it. Check that it fits comfortably and is not too loose or too tight. Repeat this step if necessary to find the optimal size.
Tip: If you want more accurate measurements, you can repeat the process several times and take the average of the measurements.
Step 4: Compare with our size chart
Now compare the measurement you noted with our size scale and choose the appropriate ring size.
| Size | Inner diameter |
| 1 | 16.5 mm |
| 2 | 17.3 mm |
| 3 | 18.1 mm |
Don’t worry too much about your ring size.
After your order you will immediately receive our LIINI fingerprint kit.
Included are original and pre-cutring templates to try on.
So you can always change to a smaller or larger ring before engraving in the worst case.
