I am looking for an ideal brilliant cut stone for an engagement ring. I found a GIA certified with the following characteristics for $10,800. Please advise if this is a good value?? One cocern of mine is that this stone did not give off the same colors and brillinace of stones of lower qualites that I saw at Tiffany & Co. Could it be the lighting? AS well would I founf more value in a similar stome though F in color and Si1 clarity for the same price? Any adice or insight is much appreciated!
