Is it an airline? Floating? I'm not sure...I know it's not a bezel. One of the ladies at work just got engaged & her halo is similar to mine. The rock sits above the actual halo...kind of like a solitaire but not really...
my ring in this picture was dirty, sorry...
It's prong set halo peg head, and the prongs are not part of the halo. The stone is set into a peg head. The peg head just happens to be set into a halo frame.
