IGI report LG790680004
3.00 ct Radiant Laboratory-Grown Diamond
86/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- Face-up spread (10.07 × 7.03 mm) is typical or better for a 3.00 ct radiant.
- G color should face up white in most settings.
- VS1 clarity is typically eye-clean in a radiant.
- No fluorescence: no haze risk to weigh.
- Medium to slightly thick girdle balances durability and weight retention.
What deserves a closer look
- A 1.43:1 length-to-width ratio is outside the classic radiant range; the outline will look more elongated than typical.
- The table 72% sits outside the typical radiant range.
- G color in a 3.00 ct radiant may show some warmth, especially at the corners.
- 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 the large table look bright but flat, with less colored fire than you expected?
- Does this CVD diamond show any brown or gray undertone face-up in daylight?
- With Very Good polish and Very Good symmetry, are there visible misaligned facets or wheel marks?
- Can you show me the inscribed report number under a loupe before it is set?
