I just bought a beautiful Hearts and Arrows diamond which is now set in a beautiful platinum semi-mount and my fiancee loves it. Now I'm wondering as to what is the best way to keep the ring looking its best and of course is a safe cleaning method. Any help with this is very much appreciated.RenatozanPS - I also want to give kudos to both Martin Sheffield of usagiacerteddiamonds (he sold me this beautiful hearts and arrows diamond) and to Bill Lieberum also known as Rockdoc (he checked out the diamond for me and was more than helpful to me in my buying decision). Anyone still looking for their diamond would be well advised to keep these names in mind.
