I'm going to say up front that I had no say in my e-ring. DH bought it as a surprise from a cousin of his who, as he put it: "has a bad habit of buying jewelry a little too early." That said, I love my little diamond ring. It looks a lot like my Mom's, and it's from DH, so I love it.
Anyone who gave me grief for wearing it, for whatever reason, is not going to be taken seriously. Who cares if somebody thinks I need a 2c compass setting in platinum, or a sunstone ringed with angel tears set in mithril?
Unless he or she's buying, in which case, my right ring finger's a 7 and a half.
