by diamondseeker2006 » Apr 27, 2017 Gorgeous rings, M!!! I love the size of your new ACA, and that CVB french cut band is beyond beautiful! To answer your question, no, it does not matter what your spacer band is made of. It just needs to be low enough to separate the other two rings without damaging the e-ring prongs itself. Who made your engraved band? It's beautiful, too!
