Minerals and crystals

I need some bling for my home, something sparkly but not fake, and no rhinestones. I'm not a rhinestone kind of girl. I have seen these minerals and agates in several different uses, and I think I might need a new sparkly night table lamp. I currently own the crystals in jewelry form and I get so many compliments on them already. Maybe the agate platters, I really love the black crystal lamp with the spider but way too much out of my price range ($3,500.00). I think I'll have to start with the agate coasters.

And aren't crystals supposed to put people in a happy place? At least that's what Spencer from the Hills claims, although I'm not sure they did him any good.
