The Carat Standard

IGI report LG760557055

2.00 ct Round Brilliant Laboratory-Grown Diamond

90/100 · Refined

A strong, composed candidate on paper.

What reads well

  • The IGI Excellent cut grade corroborates the measured proportions.
  • Excellent polish and symmetry, the top finish grades.
  • E color is in the colorless range.
  • VS1 clarity is typically eye-clean in a round brilliant.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • Table 61% sits outside the preferred round range.
  • 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 61% table is larger than typical for a round brilliant (53–59%). Large tables can read bright but flatter, with less fire and contrast.
Total depth · Closer look
59.3% is shallower than typical for a round brilliant (59.5–63%). That spreads the stone face-up but raises the risk of windowing — a glassy, see-through center.
Crown angle · Ideal
32.2° sits in the 32–36° zone where crown angles typically balance fire and brightness.
Pavilion angle · Ideal
40.9° is inside the narrow 40.5–41.3° zone where the pavilion returns light most efficiently.
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
E 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.
Cut grade · Ideal
Excellent as issued by IGI, on IGI's own scale. The measured proportions above tell you more than the label.

What to check on the exact stone

  • With a shallow 59.3% depth, can you see a glassy, see-through patch in the center?
  • Does the large table look bright but flat, with less colored fire than you expected?
  • Does this CVD diamond show any brown or gray undertone face-up in daylight?
  • Can you show me the inscribed report number under a loupe before it is set?
