Mininana, I already have a nice ring and I love it. Another thing is that my hands are not pretty. So I don't really buy a lot of rings. However, you are right. I don't have to buy a Tiffany necklace. I just don't know if non-designer jeweleries would have same quality. That will need some time to search for it.
risingsun, thanks for the recommendation. It's a gorgeous piece. I like hears on fire! The style is very formal though. I doubt it can be worn everyday.
