Thanks everyone for your input!
I tried to wear the sample for longer than 30 minutes, and the diamonds that goes all the way down the shank kept on rubbing on my other 2 fingers and it just wasn't comfortable. Also I showed it to the BF and he said that the Tacori just has a lot more details and that he likes that one a lot better. But since this setting is almost $2k less than the Tacori, it's still somewhat in the running hehe.
I'll try to get a side by side, I need to check with this other jeweler that has really good ratings on yelp.
GOG has 2 more new diamonds posted, it's both about $3000-$4000 more than the one that I posted, but it has better specs. When I get home I'll post it and see what you guys think.
