IGI report LG786661907

1.50 ct Oval Laboratory-Grown Diamond

88/100 · Refined

A strong candidate on paper; confirm its light pattern in imagery.

What reads well

The table 66% sits outside the typical oval range.
Screening only: for this oval, check images or video of the exact stone for the bow-tie (a dark band across the centre) and whether both ends look even.
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 66% table is larger than typical for an oval (53–63%). Large tables can read bright but flatter, with less fire and contrast.
Total depth · Ideal: 58.6% is within the typical 58–63.5% range for an oval, keeping weight where it contributes to face-up size and light return.
Length-to-width · Ideal: A 1.38:1 outline is within the classic 1.3–1.5:1 range for an oval.
Polish · Ideal: Excellent polish is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
Symmetry · Favorable: Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.
Girdle · Ideal: Medium To 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 · Favorable: VS1 is typically eye-clean.
Fluorescence · Ideal: None: no meaningful effect on appearance.

Does the large table look bright but flat, with less colored fire than you expected?
In a face-up video, does the bow-tie flicker as the stone tilts, or stay a fixed dark band across the center?
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?
