The Carat Standard

IGI report LG788659241

2.07 ct Oval Laboratory-Grown Diamond

84/100 · Refined

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

What reads well

  • A 1.48:1 length-to-width ratio sits in the classic oval range.
  • Face-up spread (10.76 × 7.25 mm) is typical or better for a 2.07 ct oval.
  • Table 60% and depth 58.9% fall in the typical oval range.
  • E color is in the colorless range.
  • VS1 clarity is typically eye-clean in an oval.

What deserves a closer look

  • Good polish / Very Good symmetry is below the Excellent/Very Good standard and can soften sparkle.
  • The culet is described as chipped or abraded; check whether it is visible face-up.
  • 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 60%, the table sits within the typical 53–63% range for an oval, balancing brightness with fire.
Total depth · Ideal
58.9% 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 1.48:1 outline is within the classic 1.3–1.5:1 range for an oval.
Polish · Closer look
Good polish is below the grades most buyers target and can slightly soften crispness. Worth seeing the stone in person or on video.
Symmetry · Favorable
Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.
Girdle · Ideal
Medium To Slightly Thick (Faceted): a durable girdle thickness that doesn't hide meaningful weight.
Culet · Favorable
A chipped culet is usually invisible to the eye.
Color · Ideal
E is in the colorless range and faces up white in any metal.
Clarity · Favorable
VS1 is typically eye-clean.
Fluorescence · Ideal
None: no meaningful effect on appearance.

What to check on the exact stone

  • 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?
  • With Good polish and Very Good symmetry, are there visible misaligned facets or wheel marks?
  • Can you show me the inscribed report number under a loupe before it is set?
