IGI report LG770680629

8.01 ct Round Brilliant Laboratory-Grown Diamond

85/100 · Refined

A strong, composed candidate on paper.

What reads well

Crown 33.2° / pavilion 40.3° 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.
Not stated on the report: cut grade. This is not assumed to be favorable, and confidence is lower.

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: 33.2° sits in the 32–36° zone where crown angles typically balance fire and brightness.
Pavilion angle · Closer look: 40.3° 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: VS2 is typically eye-clean.
Fluorescence · Ideal: None: no meaningful effect on appearance.

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?
