IGI report 727566177
2.33 ct Marquise Diamond
87/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 2.15:1 length-to-width ratio sits in the classic marquise range.
- Face-up spread (14.62 × 6.81 mm) is typical or better for a 2.33 ct marquise.
- Excellent polish and symmetry, the top finish grades.
- VS1 clarity is typically eye-clean in a marquise.
- Faint fluorescence: no haze risk to weigh.
What deserves a closer look
- I color in a 2.33 ct marquise may show some warmth, especially at the points.
- 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.
The reading, field by field
- Table · Ideal
- At 57%, the table sits within the typical 53–63% range for a marquise, balancing brightness with fire.
- Total depth · Closer look
- 57.6% is shallower than typical for a marquise (58–64%). That spreads the stone face-up but raises the risk of windowing — a glassy, see-through center.
- Length-to-width · Ideal
- A 2.15:1 outline is within the classic 1.85–2.2:1 range for a marquise.
- 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
- 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 · Favorable
- I may show slight warmth at the points of a marquise, especially next to white metal. Yellow or rose gold tends to complement it.
- Clarity · Favorable
- VS1 is typically eye-clean.
- Fluorescence · Favorable
- Very Slight fluorescence is rarely visible in normal lighting.
- Cut grade · Favorable
- Very Good as issued by IGI, on IGI's own scale. The measured proportions above tell you more than the label.
What to check on the exact stone
- With a shallow 57.6% depth, can you see a glassy, see-through patch in the center?
- 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?
