1.89 ct Princess Laboratory-Grown Diamond

What reads well

• A 1.01:1 length-to-width ratio sits in the classic princess range.
• Face-up spread (6.78 × 6.70 mm) is typical or better for a 1.89 ct princess.
• Table 73% and depth 73.9% fall in the typical princess range.
• Excellent polish and symmetry, the top finish grades.
• F color is in the colorless range.

What deserves a closer look

• Screening only: for this princess, check images or video of the exact stone for dark areas across the corners or a see-through centre.
• 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

• Will all four sharp corners be seated safely in V-prongs to prevent corner fractures?
• 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?
