10 Engraving ideas for the wedding rings
1. Heart rate
It's a cool idea for people who wear their smartwatches every time. You can check your heart rate from the moment you had your first kiss or the minute you made a proposal.
Quite similar to the #1, but looks more romantic. The only problem, it will be a bit weird to take your ECG immediately after your first kiss.
3. Fingerprint of your ring fingers
Of the place you met, kissed, made a proposal.
5. Moon phase
If you are into... moons :) On that day you made a proposal for example.
6. Spotify song code of the song which played during your special time
Too obvious and primitive but let it be.
8. Her voice phonogram when she said YES
You can record it using JustPressRecord, as I mentioned previously.
Related to that date. I'm not sure how this one works but at least it will look nice.
