I have to laugh reading this on a BBS where people extol the virues of 52100 vs White No 1 vs O1 and CPM154 vs CM 154 vs VG10Keep in mind that I'm only 26 and I've never even set foot into a jewelry store or even considered buying any sort of engagement ring, so maybe I'm just naive, but can the average person even tell the difference between white gold and platinum or even silver based on looks alone?
