IGI report LG775622777
2.01 ct Round Brilliant Laboratory-Grown Diamond
70/100 · Character
Distinctive trade-offs that should be viewed deliberately.
What reads well
- 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.
- Medium to slightly thick girdle balances durability and weight retention.
What deserves a closer look
- Crown 33.9° / pavilion 40° fall outside the pairing zone associated with strong light return.
- Table 65% and depth 57.9% sit 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 65% 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
- 57.9% 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
- 33.9° sits in the 32–36° zone where crown angles typically balance fire and brightness.
- Pavilion angle · Closer look
- 40° 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
- 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 · 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?
- With a shallow 57.9% 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?
