IGI report LG780666052
4.00 ct Radiant Laboratory-Grown Diamond
88/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- Face-up spread (11.42 × 7.89 mm) is typical or better for a 4.00 ct radiant.
- Table 64% and depth 65% fall in the typical radiant range.
- Excellent polish and symmetry, the top finish grades.
- D color is in the colorless range.
- FL clarity: inclusions are not a practical visual factor.
What deserves a closer look
- A 1.45:1 length-to-width ratio is outside the classic radiant range; the outline will look more elongated than typical.
- Screening only: bow-tie, windowing and contrast in a radiant can only be judged from images or video of this exact stone.
What to check on the exact stone
- 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?
