IGI report LG786682993
2.00 ct Marquise Laboratory-Grown Diamond
89/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 2.13:1 length-to-width ratio sits in the classic marquise range.
- Face-up spread (13.76 × 6.47 mm) is typical or better for a 2.00 ct marquise.
- E color is in the colorless range.
- VS1 clarity is typically eye-clean in a marquise.
- No fluorescence: no haze risk to weigh.
What deserves a closer look
- The table 65% sits outside the typical marquise range.
- Screening only: for this marquise, check images or video of the exact stone for the bow-tie and whether the two points line up end to end.
- 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 marquise (53–63%). Large tables can read bright but flatter, with less fire and contrast.
- Total depth · Ideal
- 60.1% is within the typical 58–64% range for a marquise, keeping weight where it contributes to face-up size and light return.
- Length-to-width · Ideal
- A 2.13:1 outline is within the classic 1.85–2.2:1 range for a marquise.
- Polish · Favorable
- Very Good polish is a fine result; the difference from Excellent is rarely visible without magnification.
- Symmetry · Ideal
- Excellent symmetry is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
- Girdle · Ideal
- Slightly Thick 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
- 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.
What to check on the exact stone
- 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?
- Will the ring setting use protective V-tip prongs or a bezel to safeguard the two delicate points?
- Can you show me the inscribed report number under a loupe before it is set?
