The Carat Standard

IGI report LG712589336

5.53 ct Round Brilliant Laboratory-Grown Diamond

90/100 · Refined

A strong, composed candidate on paper.

What reads well

  • Crown 35° with pavilion 40.6° sits in the well-regarded pairing zone for brightness and fire.
  • Table 55% and depth 62.5% are within the classic round brilliant range.
  • The IGI Ideal cut grade corroborates the measured proportions.
  • Excellent polish and symmetry, the top finish grades.
  • F color is in the colorless range.

What deserves a closer look

  • Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.

What to check on the exact stone

  • Does this CVD diamond show any brown or gray undertone face-up in daylight?
  • 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?
  • Can you show me the inscribed report number under a loupe before it is set?
