The cutter achieved near-perfect proportions: The 4.33mm depth (66.8% of width) prevents light leakage while the 1.18 length-to-width ratio creates a classic oval silhouette. These angles work synergistically to maintain the cornflower blue's velvety appearance while ensuring exceptional sparkle.

Cutting Insight: The 4.33mm depth represents a master cutter's solution to the cornflower blue paradox - maintaining the velvety texture while preventing dullness. At 66.8% of the width, it's precisely deep enough to concentrate color, yet shallow enough to avoid dark areas. The 6.48mm length gives impressive presence (visible even in elaborate settings) while the 5.50mm width ensures the stone doesn't appear narrow.
