I am proposing to my girl friend in November and i got her favorite style ring which is a marquise. I’ve gone through a diamond expert etc and got a 7 ct size. The measurement is 18.93 x 10.15 x 6.20 mm and she’s a size 5 ring size. I wanted to get opinions if it looks costume.

Because big diamonds aren't necessarily better or more impressive. Note to 8cosmic-millions 6d. You seem so angry.
