7 mm Solstice08/15/2007 ByJason James This is the 4th ring I have purchased from eWeddingbands. No I am not a serial divorcee, I just tend to loose wedding rings in outdoor mishaps involving water. Every time I need a new one eWeddingbands is there for me with a friendly voice on the other end of the phone. I can never seem to remember what size ring I need so I just call in and ask what I purchased last time. This is a Great company with Great people and Great quality. I should know, I keep coming back for more.
