I'm back again...just talked to Yoni from Eternity Diamonds and finally got an answer! They use 950platinum and iridium alloy. I'm waiting for my ring to be shipped (he said Monday! wahooo!!!!), and now I'd like to hear some feedback from those with this mixture. I know the preferred seems to be the Platinum-ruthenium combo, BUT seeing as that isn't what I'm getting, I'd like to "hear" about what I might be in store for with this softer metal. As far as polishing goes, how much does that cost about? And do you think it wears away the metal to much? My ring will have the milgrain on it, so is that even polishable? I've got three kids (8 twin boys and a 14 yr old daughter) and a crazy golden retriever to boot, so I'm pretty rough on my hands. Hopefully I won't regret this softer choice... bring on the stories...the good (hopefully there are some) and the ugly. Thanks in advance!
