IGI report LG825634313

1.50 ct Princess Laboratory-Grown Diamond

89/100 · Refined

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

What reads well

  • A 1.00:1 length-to-width ratio sits in the classic princess range.
  • Table 66% and depth 72.4% fall in the typical princess range.
  • Excellent polish and symmetry, the top finish grades.
  • D color is in the colorless range.
  • FL clarity: inclusions are not a practical visual factor.

What deserves a closer look

  • Screening only: bow-tie, windowing and contrast in a princess can only be judged from images or video of this exact stone.

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?
