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?
