I wear my Mene ring daily, too. And my earrings.... I don't take them off, even when I do my weekly routine Thursday lap swim. They are as shiny and beautiful as when I got them. It is interesting that shipwreck gold discovered after hundreds of years in the bottom of the sea remained intact... and seawater is so corrosive.
I am so glad to have made the decision to grow my Mene gold and platinum collection, @goldmatters. Thanks for sharing, @jonknight!
