Is it dangerous ring?

For my weddings I found an perfect wedding ring http://www.tungstenfashions.com/tungsten-carbide-r... but it have zirconia stone is it not radioactive? Will my wife shine in the night green? I like green light, even in my bedroom. My wallpapers are green, my carppet is also green, my curtains is green too.

Ok, so my fiance is 45 kg's and how will her health react fot this radiation. Should she get some weight or maybe she should try to become immune to radiation with small doses daily, before wedding?

Also is the tungste used in lightbulbs. Can I make my wedding ring shine (but not so bright) to light my room or other dark places?

But the main reason is price and health of my fiance.
