I'm with you on the shock about the price. I like the look, and the idea, when the stone is not so dark in colour at least. But a price of $300 or below is about the max I'd pay.
They really do capture my interest though. Especially because I am experiencing a trial in my personal life. I was thinking about purchasing a ring with an uncut diamond as a reminder to myself that though the situation seems murky and rough right now, beautiful things can be laying beneath the surface - just waiting to be polished into appearance if you will.
That and a girl can't have too much jewelry, right?
