I am looking at a radiant cut diamond for an engagement ring. The one I am contemplating buying is $13400. 1.90 carat. H Color. IF Clarity. No Fluorescence. 7.01x6.94x4.73. Table 64%. Depth 68.1%. Excellent Polish and Symmetry based on GIA report. Is this a good stone? Or would you recommend something else? I don't want to spend more than 15K on a stone.
