IGI report LG837628368

3.00 ct Cushion Mixed Cut Laboratory-Grown Diamond

84/100 · Refined

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

What reads well

  • Table 65% and depth 65.3% fall in the typical cushion range.
  • Excellent polish and symmetry, the top finish grades.
  • D color is in the colorless range.
  • IF clarity: inclusions are not a practical visual factor.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • A 1.42:1 length-to-width ratio is outside the classic cushion range; the outline will look more elongated than typical.
  • Face-up area is about 15% below typical cushions of this weight, suggesting hidden weight in depth.
  • Screening only: bow-tie, windowing and contrast in a cushion can only be judged from images or video of this exact stone.

What to check on the exact stone

  • Does this cushion produce broad, chunky flashes or small needle-like crushed-ice sparkle?
  • Does this HPHT-grown diamond look neutral white beside another stone in daylight, with no gray or blue cast?
  • Can you show me the inscribed report number under a loupe before it is set?
