1.00 ct Oval Laboratory-Grown Diamond

What reads well

• A 1.40:1 length-to-width ratio sits in the classic oval range.
• Face-up spread (7.81 × 5.58 mm) is typical or better for a 1.00 ct oval.
• Excellent polish and symmetry, the top finish grades.
• D color is in the colorless range.
• VVS1 clarity: inclusions are not a practical visual factor.

What deserves a closer look

• The table 66% sits outside the typical oval range.
• Screening only: bow-tie, windowing and contrast in an oval 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?
• How dark is the bow-tie shadow across the center when viewed in normal daylight?
• 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?
