Shopping for a wedding band that is mostly visible diamond. I like princess cut diamonds in a channel eternity setting with very little visible platinum though I'm fine with, if not slightly prefer, 1/2 or 3/4 eternity. Apart from being a full eternity, I found the exact style I'm looking for in THIS Leon Mege platinum and princess cut diamond wedding band. From an environmental and cost perspective would prefer a pre-loved piece. Any suggestions on specific pieces or vendors/websites to consider? If relevant I'm a size 5 (could also wear 5.25).
