IGI report LG778680695
2.71 ct Hexagon Laboratory-Grown Diamond
67/100 · Character
Distinctive trade-offs that should be viewed deliberately.
What reads well
- Excellent polish and symmetry, the top finish grades.
- D color is in the colorless range.
- VS1 clarity is typically eye-clean in a fancy shape.
- No fluorescence: no haze risk to weigh.
What deserves a closer look
- The table 79% sits outside the typical fancy shape 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 fancy shape, check images or video of the exact stone for the overall light pattern, dark areas and any see-through window.
- Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.
- The shape "Hexagonal Modified Brilliant" does not match a standard profile, so a conservative general screen was used.
The reading, field by field
- Table · Closer look
- A 79% table is larger than typical for a fancy shape (55–65%). Large tables can read bright but flatter, with less fire and contrast.
- Total depth · Closer look
- 69.7% is deeper than typical for a fancy shape (58–68%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests.
- 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
- 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 69.7% depth, does this stone face up smaller than a typical 2.71 ct hexagon?
- Does the large table look bright but flat, with less colored fire than you expected?
- Is extra carat weight trapped in the thick girdle rim where it does not add finger presence?
- Can you show me the inscribed report number under a loupe before it is set?
