More wired than a Roman Internet café

I'm getting married soon, and I'd like to put a specific inscription on my wife's ring. When we bought the rings, I suggested getting titanium ones, which she readily agreed to. Her exact quote was "Titanium is perfect. Our love is unbreakable". It stuck with me. I want to translate "Our Love is Unbreakable" into latin for the inscription. Can anyone help me out?
