The Carat Standard

GIA report 6542718196

5.00 ct Oval Diamond

77/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • A 1.59:1 length-to-width ratio is outside the classic oval range; the outline will look more elongated than typical.
  • The table 66% sits outside the typical oval range.
  • Clouds are referenced on the report; confirm the stone looks transparent rather than hazy.
  • Confirm this SI1 oval is eye-clean from an image or video; the report plot shows where inclusions sit.
  • 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 · 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 · Closer look
63.6% is deeper than typical for an oval (58–63.5%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests and may show a stronger bow-tie.
Length-to-width · Favorable
A 1.59:1 outline is longer and slimmer than the classic 1.3–1.5:1 range for an oval — a matter of taste, but worth seeing in person.
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 · Closer look
Very thin to extremely thick, faceted: thin sections of girdle are more vulnerable to chipping. A setting that protects the edge is sensible.
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 · Favorable
SI1 is often eye-clean in an oval, but not always — check where the inclusions sit.
Fluorescence · Ideal
None: no meaningful effect on appearance.

What to check on the exact stone

  • With 63.6% depth, does this stone face up smaller than a typical 5.00 ct oval?
  • Does the large table look bright but flat, with less colored fire than you expected?
  • Does the diamond look crisp and transparent in natural light, or is there any milky haze?
  • Can you show me the inscribed report number under a loupe before it is set?
