My husband was talking about buying me an anniversary band and I just couldn't believe the price difference between 10 karat and 14 karat gold! It was unreal!
We have a good, locally owned jewelry store in town and I asked the sales associate about the difference. He said we could get "more ring" in a 10 karat for our money, since we could get more, or larger diamonds in the ring for what we would pay for a 14 karat band. As Grivusangel noted, it's not like anyone can *see* whether it's 10k or 14k just by looking at it.
