IGI report LG823690346
3.00 ct Radiant Laboratory-Grown Diamond
35/100 · Investigate
The report asks for a more careful visual review.
What reads well
- A 1.30:1 length-to-width ratio sits in the classic radiant range.
- Excellent polish and symmetry, the top finish grades.
- E color is in the colorless range.
- VVS2 clarity: inclusions are not a practical visual factor.
- No fluorescence: no haze risk to weigh.
What deserves a closer look
- The table 55% and depth 82% sit outside the typical radiant range.
- 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: for this radiant, check images or video of the exact stone for the sparkle pattern (defined flashes or "crushed ice") and any dark or see-through corners.
- Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.
The reading, field by field
- Table · Favorable
- A 55% table is smaller than typical for a radiant (60–70%). Smaller tables tend to favor fire over broad, flat brightness.
- Total depth · Closer look
- 82% is deeper than typical for a radiant (61–68%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests.
- Length-to-width · Ideal
- A 1.3:1 outline is within the classic 1.2–1.5:1 range for a radiant.
- Polish · Ideal
- Excellent polish is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
- Symmetry · Ideal
- Excellent symmetry is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
- Girdle · Closer look
- Thick to very thick: a thick girdle carries weight in the rim, so the stone can face up a little smaller for its carat weight. It is durable, though.
- Culet · Ideal
- Pointed: no visible culet facet when viewed face-up.
- Color · Ideal
- E is in the colorless range and faces up white in any metal.
- Clarity · Ideal
- VVS2: inclusions, if any, are only visible under magnification.
- Fluorescence · Ideal
- None: no meaningful effect on appearance.
What to check on the exact stone
- With 82% depth, does this stone face up smaller than a typical 3.00 ct radiant?
- Is extra carat weight trapped in the thick girdle rim where it does not add finger presence?
- 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?
