3.05 ct Oval Laboratory-Grown Diamond

89/100 · Refined

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

What reads well

  • A 1.42:1 length-to-width ratio sits in the classic oval range.
  • Face-up spread (11.73 × 8.28 mm) is typical or better for a 3.05 ct oval.
  • Table 61% and depth 60.7% fall in the typical oval range.
  • Excellent polish and symmetry, the top finish grades.
  • IF clarity: inclusions are not a practical visual factor.

What deserves a closer look

  • I color in a 3.05 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.

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 HPHT-grown diamond look neutral white beside another stone in daylight, with no gray or blue cast?
  • Can you show me the inscribed report number under a loupe before it is set?
