The Carat Standard

IGI report LG775613933

1.05 ct Oval Laboratory-Grown Diamond

78/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

  • Face-up spread (9.93 × 5.00 mm) is typical or better for a 1.05 ct oval.
  • D color is in the colorless range.
  • VVS2 clarity: inclusions are not a practical visual factor.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • A 1.99:1 length-to-width ratio is outside the classic oval range; the outline will look more elongated than typical.
  • A 67.4% depth is on the deep side for an oval; deeper pavilions are associated with a stronger bow-tie and hidden weight.
  • 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.
  • 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 · Ideal
At 62%, the table sits within the typical 53–63% range for an oval, balancing brightness with fire.
Total depth · Closer look
67.4% 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 1.99:1 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 · Favorable
Very Good polish is a fine result; the difference from Excellent is rarely visible without magnification.
Symmetry · Favorable
Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.
Girdle · Ideal
Medium 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
D is in the colorless range and faces up white in any metal.
Clarity · Ideal
VVS2: inclusions, if any, are only visible under magnification.
Fluorescence · Ideal
None: no meaningful effect on appearance.

What to check on the exact stone

  • With 67.4% depth, does this stone face up smaller than a typical 1.05 ct oval?
  • In a face-up video, does the bow-tie flicker as the stone tilts, or stay a fixed dark band across the center?
  • Does this CVD diamond show any brown or gray undertone face-up in daylight?
  • Can you show me the inscribed report number under a loupe before it is set?
