3.09 ct Emerald Laboratory-Grown Diamond

What reads well

• A 1.38:1 length-to-width ratio sits in the classic emerald cut range.
• Excellent polish and symmetry, the top finish grades.
• G color should face up white in most settings.
• No fluorescence: no haze risk to weigh.
• Medium girdle balances durability and weight retention.

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 11% below typical emerald cuts of this weight, suggesting hidden weight in depth.
• G color in a 3.09 ct emerald cut may show some warmth, especially at the corners.
• 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

• With 69.6% depth, does this stone face up smaller than a typical 3.09 ct emerald?
• 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?
• Does this CVD diamond show any brown or gray undertone face-up in daylight?
