So first of all let me stress that from the conversation I've had with my fiancee I'm not sure if this is an Egyptian or Muslim or what kind of a tradition it is but he has been telling me that "In Egypt" (as he always starts) they have a 3rd ring in the ceremony that goes on top of the wedding band and engagement ring to be the "lock",Does anyone know anything about this tradition, I can't find anything online and the only thing I can find on jewelers websites are enhancers which do go on both sides or one side but I'm fairly sure this isn't the same thing.
