Poison Ring

I've been hunting for the perfect wedding band(s) for the past year and can't make up my mind.  I have a tiny budget, but I want something pretty simple so that isn't too much of a problem.  I love sparkly things so I tried on a diamond band last week just to make sure I didn't want to go in that direction, but my hands looked like a tomboy in a sequin dress.  Later that afternoon, as I built garden beds and did yard work, I realized precious gems do not belong on my fingers.  

Today I saw this ring and I'm so bummed that it is already sold.  I think this ring would be an exception to the "two simple plain bands" decision that I think I came to for my wedding rings. It has a secret chamber for poison!
