The Evolution of a Diamond Wedding Ring

She is a friend and lover of Variance.  She requested we take the diamond from her wedding ring (she is still married by the way), change the band and setting and add a moonstone.  Their son's birthstone is moonstone.  

It's not a common thing to want to change a wedding ring when you are still married to the same person.  We think of these rings as a moment in time, a snap shot of the past.  But it really does make sense if you think about it.  Why should a wedding ring not change?  People change, relationships evolve... why not rings too.
