Jeweler Andrew English has designed wedding bands which are hand-engraved with the fingerprint of the partner so that they're completely unique to each couple. They're only available by commission and come in 9, 14 and 18ct white/yellow/rose gold and platinum. The bands are available in a number of styles with the fingerprint hand-engraved on either the inside or outside of the band. There's no price listed, but I'm assuming it's a bit out of my league. Although to be fair, a stale Funyun is out of my league.
