5.00 ct Oval Diamond

66/100 · Character

Distinctive trade-offs that should be viewed deliberately.

What reads well

  • A 1.40:1 length-to-width ratio sits in the classic oval range.
  • Face-up spread (14.04 × 10.02 mm) is typical or better for a 5.00 ct oval.

What deserves a closer look

  • Confirm this SI1 oval is eye-clean from an image or video; the report plot shows where inclusions sit.
  • A 51.2% depth is shallow for an oval; check images for a see-through window in the centre.
  • Feathers are listed: check the plot for any that reach the girdle or surface, which matters for durability.
  • G color in a 5.00 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 61%, the table sits within the typical 53–63% range for an oval, balancing brightness with fire.
Total depth · Closer look
51.2% is shallower than typical for an oval (58–63.5%). That spreads the stone face-up but raises the risk of windowing — a glassy, see-through center.
Length-to-width · Ideal
A 1.4:1 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
Slightly thick 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
G is near-colorless and faces up white in most settings, though an oval can show a hint of warmth at the tips.
Clarity · Favorable
SI1 is often eye-clean in an oval, but not always — check where the inclusions sit.
Fluorescence · Favorable
Medium Blue fluorescence is rarely visible in normal lighting.

What to check on the exact stone

  • With a shallow 51.2% depth, can you see a glassy, see-through patch in the center?
  • Does the feather reach the outer edge where a setting prong could put pressure on it?
  • Is this SI1 diamond eye-clean face-up from about 10 inches away?
  • Can you show me the inscribed report number under a loupe before it is set?
