Quoted from northvibe:I mean it’s all opinions of people who don’t know you and your fiancé, but get some things she’d like in a ring, like the stone shape, material of ring and maybe a design cue

Make sure whoever you buy from shows you the diamond grade, color, etc. Don't be like my buddy who bought a ring at 9k, the engagement ended and it turns out his diamond is shitty so his ring is almost worthless. Diamond is like $1.5k.
Quality, color, where it came from, all that shit matters. Some diamonds have ugly ass voids in them. Once you see them, you can't unsee them.
