The Carat Standard

IGI report LG776643106

3.02 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 (10.52 × 7.47 mm) is typical or better for a 3.02 ct cushion.
  • Excellent polish and symmetry, the top finish grades.
  • F color is in the colorless range.
  • VVS2 clarity: inclusions are not a practical visual factor.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • A 1.41:1 length-to-width ratio is outside the classic cushion range; the outline will look more elongated than typical.
  • The table 68% sits outside the typical cushion range.
  • 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 · Closer look
A 68% table is larger than typical for a cushion (56–66%). Large tables can read bright but flatter, with less fire and contrast.
Total depth · Closer look
60.6% is shallower than typical for a cushion (61–69%). That spreads the stone face-up but raises the risk of windowing — a glassy, see-through center.
Length-to-width · Favorable
A 1.41:1 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 · Ideal
Excellent polish is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
Symmetry · Ideal
Excellent symmetry is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
Girdle · Ideal
Medium to 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 · Ideal
VVS2: inclusions, if any, are only visible under magnification.
Fluorescence · Ideal
None: no meaningful effect on appearance.

What to check on the exact stone

  • With a shallow 60.6% depth, can you see a glassy, see-through patch in the center?
  • Does the large table look bright but flat, with less colored fire than you expected?
  • Does this cushion produce broad, chunky flashes or small needle-like crushed-ice sparkle?
  • Can you show me the inscribed report number under a loupe before it is set?
