Diamond Cut — Sparkle & Proportions

Understand GIA Excellent / Very Good grading, brilliance, fire, and why cut is often the strongest driver of visible beauty.

Cut dictates how crisply light refracts toward your eye—the reason two diamonds can share specs yet look unmistakably different.

Open the interactive explorer to exaggerate brilliance vs softness while you skim this copy.

Excellent: Crowns near 34–35°, pavilion around 40.6°, tight facet meets—maximum face-up brilliance for rounds.
Very Good: Slight deviations can still sparkle impressively once set.
Below: Bellies retain weight but leak light—you pay for measurable carats you literally don’t perceive.

Fancies use different symmetry targets; always reconcile vendor videos with pavilion depth photography.
