4.00 ct Emerald Laboratory-Grown Diamond

What reads well

• Excellent polish and symmetry, the top finish grades.
• E color is in the colorless range.
• IF clarity: inclusions are not a practical visual factor.
• No fluorescence: no haze risk to weigh.
• Slightly thick girdle balances durability and weight retention.

What deserves a closer look

• A 1.55:1 length-to-width ratio is outside the classic emerald cut range; the outline will look more elongated than typical.
• Face-up area is about 13% below typical emerald cuts of this weight, suggesting hidden weight in depth.
• A 72% 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 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.

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?
