2.01 ct Round Brilliant Laboratory-Grown Diamond

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.
• VS2 clarity is typically eye-clean in a round brilliant.
• No fluorescence: no haze risk to weigh.

What deserves a closer look

• Crown 33.1° / pavilion 40.4° fall outside the pairing zone associated with strong light return.
• Table 62% 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 62% 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

59.1% 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

33.1° sits in the 32–36° zone where crown angles typically balance fire and brightness.

Pavilion angle · Closer look

40.4° is shallower than the narrow 40.5–41.3° zone. Shallow pavilions can let light pass straight through, looking glassy.

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

None: 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

VS2 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

• Does a gray ring or glassy patch show around the center when you look straight down?
• With a shallow 59.1% 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?
• Can you show me the inscribed report number under a loupe before it is set?
