The Carat Standard

IGI report LG380912718

2.00 ct Emerald Laboratory-Grown Diamond

82/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

  • A 1.34:1 length-to-width ratio sits in the classic emerald cut range.
  • E color is in the colorless range.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • SI1 in an emerald cut: the open step-cut table makes inclusions easier to see. View an image or video of this exact stone.
  • Screening only: for this emerald cut, check images or video of the exact stone for the "hall of mirrors" step pattern, any see-through window under the table and clean corners.
  • Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.
  • Not stated on the report: depth. This is not assumed to be favorable, and confidence is lower.

The reading, field by field

Table · Ideal
At 67%, the table sits within the typical 60–69% range for an emerald cut, balancing brightness with fire.
Length-to-width · Ideal
A 1.34:1 outline is within the classic 1.3–1.5:1 range for an emerald cut.
Polish · Favorable
Very Good polish is a fine result; the difference from Excellent is rarely visible without magnification.
Symmetry · Favorable
Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.
Girdle · Ideal
Slightly thick to thick: a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal
Long: a keel-line culet, normal for elongated step and modified cuts.
Color · Ideal
E is in the colorless range and faces up white in any metal.
Clarity · Closer look
SI1 in a step cut often shows inclusions through the open table. Confirm eye-cleanliness with images or video.
Fluorescence · Ideal
None: no meaningful effect on appearance.

What to check on the exact stone

  • Step cuts show inclusions openly—is this SI1 diamond eye-clean through the table from about 10 inches away?
  • With Very Good polish and Very Good symmetry, are there visible misaligned facets or wheel marks?
  • Can you show me the inscribed report number under a loupe before it is set?
