The Carat Standard

GIA report 1539727054

4.00 ct Pear Laboratory-Grown Diamond

87/100 · Refined

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

What reads well

  • A 1.61:1 length-to-width ratio sits in the classic pear range.
  • Excellent polish and symmetry, the top finish grades.
  • D color is in the colorless range.
  • VVS1 clarity: inclusions are not a practical visual factor.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • A 65.4% depth is on the deep side for a pear; deeper pavilions are associated with a stronger bow-tie and hidden weight.
  • Thick to very thick girdle: a thick girdle carries hidden weight and can reduce face-up size (thicker points are common in fancy shapes).
  • Screening only: bow-tie, windowing and contrast in a pear 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.

What to check on the exact stone

  • With 65.4% depth, does this stone face up smaller than a typical 4.00 ct pear?
  • Will the ring setting use a protective V-tip prong or bezel to safeguard the delicate point?
  • Is extra carat weight trapped in the thick girdle rim where it does not add finger presence?
  • Can you show me the inscribed report number under a loupe before it is set?
