First time poster here considering buying a princess cut ring online. Can someone with knowledge of this cut please advise on color? I'm considering F-H color grades, but feel like I need to narrow this down so I'm not so overwhelmed looking at so many rings. Suppose a G and H were put side-by-side, would the average person be able to tell a difference? What about a F and an H? My goal is to have as white a stone as possible without someone saying..."ahhhh you went with the lower color grade to save money didn't you." Joking but you get the point. Thanks.
