I like it as costume jewelry, it just doesn't look "real" to me. The size + shape makes it look like a cocktail ring rather than fine jewelry.
This is where I am. It looks more like a statement piece than an engagement ring. I'm not a huge fan of heart shaped diamonds anyways, though the quality of the stone looks amazing.
NMS, but her style is kind of extreme in general. Cool for her. I'll also say that I would not pass up a large good quality diamond in any shape if someone gave it to me.
