The Carat Standard

IGI report LG380912718

2.00 ct Emerald Laboratory-Grown Diamond

79/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

  • A 1.34:1 length-to-width ratio sits in the classic emerald cut range.
  • E color is in the colorless range.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • SI1 in an emerald cut: the open step-cut table makes inclusions easier to see. View an image or video of this exact stone.
  • Face-up area is about 17% below typical emerald cuts of this weight, suggesting hidden weight in depth.
  • Screening only: windowing, contrast and the step-cut "hall of mirrors" pattern in an emerald cut can only be judged from images or video of this exact stone.
  • Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.
  • Not stated on the report: depth. This is not assumed to be favorable, and confidence is lower.

What to check on the exact stone

  • Is this SI1 diamond eye-clean face-up from about 10 inches away?
  • With open step facets, is the center completely eye-clean without any visible dark marks?
  • With Very Good polish and Very Good symmetry, are there visible misaligned facets or wheel marks?
  • Can you show me the inscribed report number under a loupe before it is set?
