Shopaholic? Me?

I have come across these Benchmark rings which really caught my eye. They are made of tungsten but I am not sure I know much about tungsten. I did a search on wikipedia for Tungsten but really I was not enlightened. What I do know is that the prices are reasonable and the rings look chic. Bearing in mind that I am a yellow gold person, I think I will stick with yellow gold but if you are into silver or platinum, then tungsten could probably be an alternative choice!
