Etsy store fabuluster will send you a little casting that you stick your finger into and turn the results into a pretty novel wedding band.

I would have said unique – but a journalist I once met from Germany had something similar.

There are a few different varieties available and they are reasonably cheap (at $150USD).

The author

Nathan runs St Eutychus. He loves Jesus. His wife. His daughter. His son. His other daughter. His dog. Coffee. And the Internet. He is the pastor of City South Presbyterian Church, a church in Brisbane, a graduate of Queensland Theological College (M. Div) and the Queensland University of Technology (B. Journ). He spent a significant portion of his pre-ministry-as-a-full-time-job life working in Public Relations, and now loves promoting Jesus in Brisbane and online. He can't believe how great it is that people pay him to talk and think about Jesus. If you'd like to support his writing financially you can do that by giving to his church.
