Diamond Cut

EMERALD VS ASSCHER DIAMOND CUT:

Emeralds and asschers are very similar. The only difference is the L:W ratio. Emerald cuts are rectangular while asscher cuts are square. Value or quality will be identical for both Emerald and Asscher cut Diamonds. It is up to your personal preference or setting style.

  • Depth: 60% to 69% (under 65% is relatively hard to find) you don’t need any built-up depth to maintain brilliance, you should go as low as possible in terms of depth
  • Table: 61% to 67%
  • Girdle thin to slightly thick.
  • The classic emerald cut diamond has a length to width ratio of around 1.50
  • VS2 Clarity for the best value
  • Color D-F
  • suited for diamonds which have the superior clarity and color

Disadvantage:

  • Overlap between a Classic Asscher-cut and Square Emerald shape, you should go for Asscher-Cut diamond.

Asscher Diamond Cut

The modern asscher cut diamond is similar to a square emerald cut, usually with larger step facets, a higher crown, and a smaller table.
