Some halos are designed to have an airline between the stone and the setting. But sometimes, a stone that is too small is set it a halo, and that is not a good thing. I do not like a gap between stone and halo in a setting like that, personally.
It's a matter of personal preference. Some women like a small airline and some don't like any degree of openness at all. You have to ask yourself which you prefer.
Can you take a photo of you ring from a straight on point of viewing it? We're seeing a slight angled view which is a little deceiving.
I don't like the way the stone is seated in the halo, I find the halo too much for the center stone, the setting looks like a bulls eye to me, I'm not fond of the pave in the band, versus prong set in the halo, and the center stone doesn't appear (although this can be misleading due to angle and light) to be well cut.
Also, while I don't mind an airline, this stone seems to be set slightly unevenly as the gap doesn't seem to be uniform around the whole stone.
So, all up, not a ring I'd buy. BUT TO EACH HIS OWN, and for every person who doesn't like this ring, you'll find just as many people who do. Since one of the photos came from 'their facebook page' I am assuming this isn't your ring but that you're considering a purchase.
If, on the other hand, you're just looking for people to criticize somebody else's ring, you need to be clear that this is NOT your ring, or a ring you're considering purchasing. Cryptic comments that side-step questions from people trying to respond to your questions aren't really appreciated.
I'm not a fan either. If you want a double halo we can point you to jewelers who can do them nicely. We would also need your budget. The cut of that stone in the ring looks questionable as previously stated.
