The Carat Standard

IGI report LG801660374

1.07 ct Princess Laboratory-Grown Diamond

92/100 · Signature

An unusually disciplined report profile.

What reads well

  • A 1.02:1 length-to-width ratio sits in the classic princess range.
  • Face-up spread (5.71 × 5.59 mm) is typical or better for a 1.07 ct princess.
  • Table 67% and depth 71.9% fall in the typical princess range.
  • Excellent polish and symmetry, the top finish grades.
  • D color is in the colorless range.

What deserves a closer look

  • Screening only: for this princess, check images or video of the exact stone for dark areas across the corners or a see-through centre.

What to check on the exact stone

  • Will all four sharp corners be seated safely in V-prongs to prevent corner fractures?
  • 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?
