IGI report LG780615546

3.03 ct Round Brilliant Laboratory-Grown Diamond

95/100 · Signature

An unusually disciplined report profile.

What reads well

Crown 34° with pavilion 40.9° sits in the well-regarded pairing zone for brightness and fire.
The IGI Ideal cut grade corroborates the measured proportions.
Excellent polish and symmetry, the top finish grades.
D color is in the colorless range.
VVS1 clarity: inclusions are not a practical visual factor.

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: 61.2% 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: 34° sits in the 32–36° zone where crown angles typically balance fire and brightness.
Pavilion angle · Ideal: 40.9° is inside the narrow 40.5–41.3° zone where the pavilion returns light most efficiently.
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: D is in the colorless range and faces up white in any metal.
Clarity · Ideal: VVS1: inclusions, if any, are only visible under magnification.
Fluorescence · Ideal: None: no meaningful effect on appearance.
Cut grade · Ideal: Ideal as issued by IGI, on IGI's own scale. The measured proportions above tell you more than the label.

Does the large table look bright but flat, with less colored fire than you expected?
Does this HPHT-grown diamond look neutral white beside another stone in daylight, with no gray or blue cast?
Can I see this stone in soft daylight away from store spotlights to verify its sparkle?
Can you show me the inscribed report number under a loupe before it is set?
