IGI report LG779658575
2.50 ct Radiant Laboratory-Grown Diamond
78/100 · Considered
A balanced profile with a few questions to carry forward.
What reads well
- A 1.40:1 length-to-width ratio sits in the classic radiant range.
- Excellent polish and symmetry, the top finish grades.
- D color is in the colorless range.
- VS1 clarity is typically eye-clean in a radiant.
- No fluorescence: no haze risk to weigh.
What deserves a closer look
- The table 57% and depth 72% sit outside the typical radiant range.
- 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 57% table is smaller than typical for a radiant (60–70%). Smaller tables tend to favor fire over broad, flat brightness.
- Total depth · Closer look
- 72% 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 1.4:1 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 · Ideal
- Thick: a durable girdle thickness that doesn't hide meaningful weight.
- Culet · Ideal
- Pointed: no visible culet facet when viewed face-up.
- Color · Ideal
- D is in the colorless range and faces up white in any metal.
- Clarity · Favorable
- VS1 is typically eye-clean.
- Fluorescence · Ideal
- None: no meaningful effect on appearance.
What to check on the exact stone
- With 72% depth, does this stone face up smaller than a typical 2.50 ct radiant?
- 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?
