IGI report LG791623013

7.01 ct Round Brilliant Laboratory-Grown Diamond

89/100 · Refined

A strong, composed candidate on paper.

What reads well

Crown 36.4° / 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.

Table · Closer look: A 60% 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 · Ideal: 60.7% 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 · Closer look: A 36.4° crown is steeper than the typical 32–36° zone. Steep crowns can add fire, but only pair well with a slightly shallower pavilion.
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 · 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: F is in the colorless range and faces up white in any metal.
Clarity · Ideal: VVS2: inclusions, if any, are only visible under magnification.
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.

Does a gray ring or glassy patch show around the center when you look straight down?
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?
