Joanna Krupa -- Look At My Massive ... Diamond Ring

What's more distracting than Joanna Krupa's giant boobs spilling out of a skin-tight gold dress? Her humungous DIAMOND ring ... a ring SO BIG it blinded half a city block (maybe) ... and we got it up close.

Our photog spotted the "Real Housewives of Miami" star Saturday night in L.A. and asked to see the massive rock on her finger, considering JK tied the knot Thursday with Romain Zago ... in a wedding that reportedly cost $1 MILLION.

You may have seen pics, but nothing can prepare you for how HUGE the radiant-cut yellow diamond is up close ... seriously, you have to see it. Even Jennifer Aniston would be jealous.
