The Etsy.com maker Fabuluster makes this sterling silver ring that gets imprinted with your fingerprint. It can be made out of any metal, though. And as you know (especially if you were ever in jail!) everyone has different fingerprints. So it’s a very sentimental way to do a wedding band. You could also use this as a friendship ring, or any sort of love ring. Fingerprint Ring @ Etsy.com
If you’re curious about the process, this is what goes on:
I send you my Impression Kit in the mail. Once you receive it, imprint the entire length of your finger and/or your fiancés finger separately. Then you mail that back to me. Once I receive it here in my studio in beautiful coastal Maine, I make a wax form from the impression material. Then utilizing the ancient lost wax casting process, I turn that impression into a metal ring utilizing gold or silver.
