IGI report LG754594050
3.00 ct Square Cushion Laboratory-Grown Diamond
86/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 1.01:1 length-to-width ratio sits in the classic cushion range.
- Table 57% and depth 68.4% fall in the typical cushion range.
- Excellent polish and symmetry, the top finish grades.
- D color is in the colorless range.
- VVS1 clarity: inclusions are not a practical visual factor.
What deserves a closer look
- Face-up area is about 12% below typical cushions of this weight, suggesting hidden weight in depth.
- Thick to very thick girdle: a thick girdle carries hidden weight and can reduce face-up size (thicker points are common in fancy shapes).
- 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?
- Is extra carat weight trapped in the thick girdle rim where it does not add finger presence?
- 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?
