3.00 ct Marquise Laboratory-Grown Diamond

What reads well

• A 1.94:1 length-to-width ratio sits in the classic marquise range.
• Face-up spread (14.45 × 7.43 mm) is typical or better for a 3.00 ct marquise.
• D color is in the colorless range.
• VVS2 clarity: inclusions are not a practical visual factor.
• No fluorescence: no haze risk to weigh.

What deserves a closer look

• The table 66% sits outside the typical marquise range.
• 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 marquise 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

• Does the large table look bright but flat, with less colored fire than you expected?
• Will the ring setting use protective V-tip prongs or a bezel to safeguard the two delicate points?
• Is extra carat weight trapped in the thick girdle rim where it does not add finger presence?
• Does this CVD diamond show any brown or gray undertone face-up in daylight?
