2.51 ct Oval Diamond

89/100 · Refined

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

What reads well

  • A 1.50:1 length-to-width ratio sits in the classic oval range.
  • Face-up spread (11.08 × 7.37 mm) is typical or better for a 2.51 ct oval.
  • Table 58% and depth 63.3% fall in the typical oval range.
  • Excellent polish and symmetry, the top finish grades.
  • VVS2 clarity: inclusions are not a practical visual factor.

What deserves a closer look

  • H color in a 2.51 ct oval may show some warmth, especially at the tips.
  • 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.

The reading, field by field

Table · Ideal
At 58%, the table sits within the typical 53–63% range for an oval, balancing brightness with fire.
Total depth · Ideal
63.3% 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 1.5:1 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 · Ideal
Excellent symmetry is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
Girdle · Ideal
Medium to thick (faceted): a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal
None: no visible culet facet when viewed face-up.
Color · Favorable
H is near-colorless and faces up white in most settings, though an oval can show a hint of warmth at the tips.
Clarity · Ideal
VVS2: inclusions, if any, are only visible under magnification.
Fluorescence · Ideal
Faint: no meaningful effect on appearance.

What to check on the exact stone

  • Does the feather reach the outer edge where a setting prong could put pressure on it?
  • In a face-up video, does the bow-tie flicker as the stone tilts, or stay a fixed dark band across the center?
  • Can you show me the inscribed report number under a loupe before it is set?
