The Carat Standard

IGI report LG820604716

2.00 ct Radiant Laboratory-Grown Diamond

87/100 · Refined

A strong candidate on paper; confirm its light pattern in imagery.

What reads well

  • A 1.41:1 length-to-width ratio sits in the classic radiant range.
  • Face-up spread (8.67 × 6.13 mm) is typical or better for a 2.00 ct radiant.
  • Excellent polish and symmetry, the top finish grades.
  • F color is in the colorless range.
  • VVS1 clarity: inclusions are not a practical visual factor.

What deserves a closer look

  • The table 73% sits 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 · Closer look
A 73% table is larger than typical for a radiant (60–70%). Large tables can read bright but flatter, with less fire and contrast.
Total depth · Closer look
69.3% 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 1.41:1 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
F is in the colorless range and faces up white in any metal.
Clarity · Ideal
VVS1: inclusions, if any, are only visible under magnification.
Fluorescence · Ideal
None: no meaningful effect on appearance.

What to check on the exact stone

  • With 69.3% depth, does this stone face up smaller than a typical 2.00 ct radiant?
  • 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?
