The Carat Standard

IGI report LG826611139

3.00 ct Cushion Laboratory-Grown Diamond

80/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

  • Face-up spread (10.94 × 7.07 mm) is typical or better for a 3.00 ct cushion.
  • Table 61% and depth 64.4% fall in the typical cushion range.
  • Excellent polish and symmetry, the top finish grades.
  • E color is in the colorless range.
  • VVS2 clarity: inclusions are not a practical visual factor.

What deserves a closer look

  • A 1.55:1 length-to-width ratio is outside the classic cushion range; the outline will look more elongated than typical.
  • Screening only: bow-tie, windowing and contrast in a cushion can only be judged from images or video of this exact stone.
  • Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.

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?
  • Can you show me the inscribed report number under a loupe before it is set?
