The Carat Standard

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?
