Video Analysis Summary (see video ) The 15-second macro video demonstrates a clear and pronounced moderate color change: gray-blue/gray body color in diffused/daylight lighting shifts to vivid purplish-pink/reddish-pink in warmer/direct spotlight angles. The shift is authentic, noticeable, and well-captured during smooth 360° rotation. The stone shows excellent lustre, sharp facet alignment, high brilliance, no windowing, and eye-clean to very slightly included appearance (no large fractures or clouds visible).
Key Technical Attributes:
