I am turning to tPF for shopping advice AGAIN! 
My dad is looking for a ring to buy my mom for Christmas. She no longer wears her wedding set because the gold is getting thin and she is afraid to have it re-done or messed with in any way. They have been married for almost 30 years. It was a small inexpensive set but means the world to her and she doesn't want a new one.
However, she does want a ring of some kind. She would be happy with a $10 fake ring from eBay, but my dad wants to get her something nice. Even though they have plenty of cash on hand and even more in investments, he doesn't want to spend more than a couple of hundred. We found a nice anniversary band for $250 at a jewelry store, but he doesn't really want to spend even that much! I'm trying to convince him to go with the ring at the jewelry store (very pretty and simple but sparkly and beautiful!).
In the meantime I thought I would ask for advice here...
