Yes, you can put a fingerprint on a piece of handwriting jewelry. We can replace the handwriting with a fingerprint in that case. We can also put a stamped message on them, if you prefer.
For pieces that are narrower than the oval of a fingerprint, we take a distinctive section of the fingerprint to put on the piece. For an example of this, see our wide band fingerprint ring: https://www.heartonyourwrist.com/fingerprint-ring-wide-band/
When ordering, just upload the fingerprint instead of the handwriting, and leave a note that you want us to use the fingerprint instead.
If you want a stamped message instead of the fingerprint, just leave a note that you want us to use your message instead.
