A platinum and 18K yellow gold three-stone ring centering a GIA-certified 5.02 carat cushion modified brilliant diamond graded N color and VS1 clarity, flanked by two GIA-certified natural Fancy Vivid Yellow cushion modified brilliant diamonds totaling 1.44 carats, for a combined 6.46 carats. GIA grades the center stone N color — however, its Medium Blue fluorescence actively counteracts warmth in natural and mixed lighting, causing the stone to face up visually whiter than the grade alone suggests; buyers familiar with fluorescence behavior will recognize this as a meaningful value consideration. Note that a prior EGL grading report listed this stone as J color — the GIA report (the definitive standard) grades it N, and buyers should reference GIA #6461349234 for the authoritative assessment.
