Altering my Engagement Ring!!!

I love my diamond... I wished it had been a bit larger, but it's the perfect diamond, literally. He went with quality versus quantity. But, my friend works for a jeweler and brought me there today to look at wedding bands. My setting is low so every wedding band would not fit properly. I don't like the look of rounded bands. She asked if I would be willing to switch the band itself to one that pops the diamond up higher. I tried on a solitaire with the same size diamond as mine (.70 Carats), with five prongs versus my four prong. Holy shit! The ring looks fab! And even more amazing with the wedding band(s). I'm actually doing stackable. So, I decided to change the setting. I'm having a conversation with my fiancé tonight. Basically, the wedding bands weren't siting right with what he got me, and the jeweler said that give prongs protects it better.
