jewelry backup

I "backed up" DH's ring last night. This is what it looks like:

As you can see, it's pretty unique. I'm thinking of trying to find another one, so that we have a "spare" just in case. There's no markings on the ring to indicate who the designer is, just the metal content (gold and paladium). There's a single diamond flush-set into one of the pieces. Those little straight pieces hold the top and bottom rings together, and the smaller trapezoid shapes shift and slide around.

But now we have pictures, more than just the single shot in our wedding album. Maybe, worst case scenario, we could go to a jeweler and have something like this made. Hopefully the situation will never come up again.
