The Carat Standard

IGI report LG766624993

2.01 ct Round Brilliant Laboratory-Grown Diamond

88/100 · Refined

A strong, composed candidate on paper.

What reads well

  • Table 59% and depth 61% are within the classic round brilliant range.
  • D 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

  • Crown 33.6° / pavilion 40.2° fall outside the pairing zone associated with strong light return.
  • 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 59%, the table sits within the typical 53–59% range for a round brilliant, balancing brightness with fire.
Total depth · Ideal
61% is within the typical 59.5–63% range for a round brilliant, keeping weight where it contributes to face-up size and light return.
Crown angle · Ideal
33.6° sits in the 32–36° zone where crown angles typically balance fire and brightness.
Pavilion angle · Closer look
40.2° is shallower than the narrow 40.5–41.3° zone. Shallow pavilions can let light pass straight through, looking glassy.
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 · Favorable
Medium to thick (faceted): durable, on the thicker side for a round brilliant, so a little weight sits in the rim.
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.
Cut grade · Favorable
Very Good 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

  • Does a gray ring or glassy patch show around the center when you look straight down?
  • Does this CVD diamond show any brown or gray undertone face-up in daylight?
  • 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?
