2.50 ct Asscher Laboratory-Grown Diamond

89/100 · Refined

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

What reads well

  • A 1.03:1 length-to-width ratio sits in the classic Asscher / square emerald range.
  • Face-up spread (7.46 × 7.24 mm) is typical or better for a 2.50 ct Asscher / square emerald.
  • Table 63% and depth 69.2% fall in the typical Asscher / square emerald range.
  • Excellent polish and symmetry, the top finish grades.
  • VVS2 clarity: inclusions are not a practical visual factor.

What deserves a closer look

  • G color in a 2.50 ct Asscher / square emerald may show some warmth, especially at the corners.
  • Screening only: for this Asscher / square emerald, check images or video of the exact stone for the concentric "hall of mirrors", the windmill pattern at the corners and any see-through window.
  • 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 open step facets, is the center completely eye-clean without any visible dark marks?
  • Does this CVD diamond show any brown or gray undertone face-up in daylight?
  • Can you show me the inscribed report number under a loupe before it is set?
