1.50 ct Asscher Laboratory-Grown Diamond

What reads well

• A 1.04:1 length-to-width ratio sits in the classic Asscher / square emerald range.
• Face-up spread (6.64 × 6.39 mm) is typical or better for a 1.50 ct Asscher / square emerald.
• Excellent polish and symmetry, the top finish grades.
• E color is in the colorless range.
• VVS2 clarity: inclusions are not a practical visual factor.

What deserves a closer look

• A 71% table is very large for a step cut, which can flatten the hall-of-mirrors effect.
• Screening only: windowing, contrast and the step-cut "hall of mirrors" pattern in an Asscher / square emerald 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

• Can you see straight through the center (windowing), or does it reflect clean steps?
• 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?
