Observing GIA Diamond Color
In this clip we take a critical look, upside down and face up against a flat white background of 5 princess cut diamonds. An E color, 3 G colors, an H and an I color. The lighting is properly calibrated and shows you how diamond color is observed in a lab setting. The lighting is also GIA approved for proper color grading and observation. The only limitations are the setting of your monitor.
