need your help please- size of melee on this halo ring?

[TruLuv858]

Hi All! I love love love this double halo... while the shank and surrounding diamonds are beautiful- they are not what I am interested in... I will likely do a simple pave band. This is Jessica Biel 's Engagment ring. Please help me decipher the stone size on the double halo...are my eyes playing tricks on me or is the melee around the stone larger than the second halo? There seems to be a nice curve along the second halo, which makes it look super delicate. I figured if anyone could help me best relay this information to the jeweler- you all could!
