IGI report LG823638683
1.50 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 (8.34 × 5.75 mm) is typical or better for a 1.50 ct radiant.
- Table 65% and depth 64.3% fall in the typical radiant range.
- Excellent polish and symmetry, the top finish grades.
- F color is in the colorless range.
- VVS2 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.
- 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 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?
