The Carat Standard

IGI report LG678537780

1.19 ct Round Brilliant Laboratory-Grown Diamond

94/100 · Signature

An unusually disciplined report profile.

What reads well

  • Crown 33.4° with pavilion 40.9° sits in the well-regarded pairing zone for brightness and fire.
  • The IGI Ideal cut grade corroborates the measured proportions.
  • Excellent polish and symmetry, the top finish grades.
  • E color is in the colorless range.
  • VS1 clarity is typically eye-clean in a round brilliant.

What to check on the exact stone

  • With a shallow 59.2% depth, can you see a glassy, see-through patch in the center?
  • Does the large table look bright but flat, with less colored fire than you expected?
  • 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?
