Decorative lobster clasps in gold, platinum, etc.

[preswine]

I'm looking for decorative lobster/parrot clasps to be used as a (functional) charm on a necklace. The function is to make it easy to clip something to the necklace for safe keeping.

I really like this clasp:

There seems to be a whole collection of animal clasps just like it. Unfortunately, these pieces are in sterling silver, which is somewhat high maintenance and, in my opinion, isn't really a precious metal anyway (not for the last hundred years at least).

Does anyone know where I can find similarly decorative pieces in gold or platinum-group metals (or even Argentium Silver for its lower maintenance)? G&S sells clasps in all the metals of interest, but nothing I'd consider decorative.
