The Carat Standard

IGI report LG816615566

1.50 ct Round Brilliant Laboratory-Grown Diamond

94/100 · Signature

An unusually disciplined report profile.

What reads well

  • Table 58% and depth 61% are within the classic round brilliant range.
  • The IGI Excellent cut grade corroborates the measured proportions.
  • Excellent polish and symmetry, the top finish grades.
  • E color is in the colorless range.
  • VVS2 clarity: inclusions are not a practical visual factor.

What to check on the exact stone

  • Can I see this stone in soft daylight away from store spotlights to verify its sparkle?
  • Does the sparkle look bright and even all the way out to the edges?
  • 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?
