the stones that most of you all find ugly!
Garnet: one of my favorites, especially the mozambique garnet. I actually don't like rubies because I don't find the red to be "deep" enough compared to a garnet.
Peridot: I love this in studs. I love when I can find the kind of "olive" colored colored ones.
Smozy quartz: again in studs
Champagne colored diamonds, mostly in studs (or like a tennis bracelet)
I have a champagne brown pearl set in a "shell" that some folks go ga-ga over when they see it.
Finally, my birthstone is aquamarine--not my favorite, but I do have a cool college class ring with the stone.
