The Most Important C
Cut
Cut is the only C that's entirely a product of human craftsmanship — and it's the single biggest driver of a diamond's beauty. A perfectly cut diamond returns nearly all entering light as brilliance and fire.
GIA grades cut from Excellent to Poor. AGS uses Ideal as their top grade. Look exclusively for Excellent (GIA) or Ideal (AGS).
Key metrics: table %, depth %, crown angle, pavilion angle. Whiteflash's A CUT ABOVE® diamonds add ASET scope verification of ideal light performance.
