IGI report LG788669086

2.00 ct Cushion Laboratory-Grown Diamond

88/100 · Refined

A strong candidate on paper; confirm its light pattern in imagery.

What reads well

  • Face-up spread (8.72 × 6.22 mm) is typical or better for a 2.00 ct cushion.
  • Table 66% and depth 67.4% fall in the typical cushion range.
  • F color is in the colorless range.
  • VS1 clarity is typically eye-clean in a cushion.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • A 1.40:1 length-to-width ratio is outside the classic cushion range; the outline will look more elongated than typical.
  • Screening only: for this cushion, check images or video of the exact stone for the facet pattern (bold, chunky flashes or finer "crushed ice") and any dark areas under the table.
  • Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.

The reading, field by field

Table · Ideal
At 66%, the table sits within the typical 56–66% range for a cushion, balancing brightness with fire.
Total depth · Ideal
67.4% is within the typical 61–69% range for a cushion, keeping weight where it contributes to face-up size and light return.
Length-to-width · Favorable
A 1.4:1 outline is longer and slimmer than the classic 1–1.35:1 range for a cushion — a matter of taste, but worth seeing in person.
Polish · Favorable
Very Good polish is a fine result; the difference from Excellent is rarely visible without magnification.
Symmetry · Favorable
Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.
Girdle · Ideal
Thin To Slightly Thick (Faceted): a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal
Pointed: no visible culet facet when viewed face-up.
Color · Ideal
F is in the colorless range and faces up white in any metal.
Clarity · Favorable
VS1 is typically eye-clean.
Fluorescence · Ideal
None: no meaningful effect on appearance.

What to check on the exact stone

  • Does this cushion produce broad, chunky flashes or small needle-like crushed-ice sparkle?
  • Does this CVD diamond show any brown or gray undertone face-up in daylight?
  • With Very Good polish and Very Good symmetry, are there visible misaligned facets or wheel marks?
  • Can you show me the inscribed report number under a loupe before it is set?
