I think that it all depends on how much you like pink? I think that peridot is a nice color and I have seen the peridot green with pink sashes on bridesmaids dresses. I think they were at AlfredAngelos.com and I think even davidsbridal.com. but be careful if the green is lite it might make the silver look weird.

or the silver make the green look weird. I hope I helped a little bit.
good luck
