The Carat Standard

IGI report LG789611793

2.00 ct Marquise Laboratory-Grown Diamond

89/100 · Refined

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

What reads well

  • A 1.94:1 length-to-width ratio sits in the classic marquise range.
  • Face-up spread (12.68 × 6.54 mm) is typical or better for a 2.00 ct marquise.
  • Excellent polish and symmetry, the top finish grades.
  • D color is in the colorless range.
  • VS2 clarity is typically eye-clean in a marquise.

What deserves a closer look

  • A 64.4% depth is on the deep side for a marquise; deeper pavilions are associated with a stronger bow-tie and hidden weight.
  • Screening only: for this marquise, check images or video of the exact stone for the bow-tie and whether the two points line up end to end.
  • 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 · Ideal
At 60%, the table sits within the typical 53–63% range for a marquise, balancing brightness with fire.
Total depth · Closer look
64.4% is deeper than typical for a marquise (58–64%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests and may show a stronger bow-tie.
Length-to-width · Ideal
A 1.94:1 outline is within the classic 1.85–2.2:1 range for a marquise.
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
Medium To Slightly Thick (Faceted): 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
VS2 is typically eye-clean.
Fluorescence · Ideal
None: no meaningful effect on appearance.

What to check on the exact stone

  • With 64.4% depth, does this stone face up smaller than a typical 2.00 ct marquise?
  • Is this VS2 diamond eye-clean face-up from about 10 inches away?
  • In a face-up video, does the bow-tie flicker as the stone tilts, or stay a fixed dark band across the center?
  • Can you show me the inscribed report number under a loupe before it is set?
