So this should be the last post on the ring for awhile.
Well we got the ring back yesterday and you can really tell they've done some work on it. They've noticeably tipped each of the four prongs on the center stone so that they wrap over the edge of the stone. It may come loose over time, but I doubt this baby will fall out again.
At any rate, the store manager was very gracious and still offered to exchange or refund the ring, and we have until the end of the year to make a decision. We spent most of the afternoon window shopping and pricing rings at other stores in the mall. Fun for me; not so fun for Sweetie. So I made sure we stopped off at some of the places he likes, Game Stop, Babbages, and Game Workshop.
One thing we're concerned with for the future is that if we move to Eugene, OR (one of the places we're considering in the distant future) the nearest branch of this jeweler is in Portland. We think we have it bad now with a 50 - 60 mile round trip.
