4.50 ct Pear Laboratory-Grown Diamond
89/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 1.57:1 length-to-width ratio sits in the classic pear range.
- Face-up spread (14.70 × 9.34 mm) is typical or better for a 4.50 ct pear.
- Table 62% and depth 60.8% fall in the typical pear range.
- Excellent polish and symmetry, the top finish grades.
- E color is in the colorless range.
What deserves a closer look
- Screening only: for this pear, check images or video of the exact stone for the bow-tie, even shoulders and a point that lines up with the centre of the rounded end.
- Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.
The reading, field by field
- Table · Ideal
- At 62%, the table sits within the typical 53–63% range for a pear, balancing brightness with fire.
- Total depth · Ideal
- 60.8% is within the typical 58–64% range for a pear, keeping weight where it contributes to face-up size and light return.
- Length-to-width · Ideal
- A 1.57:1 outline is within the classic 1.45–1.75:1 range for a pear.

- Symmetry · Ideal
- Excellent symmetry is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.

What to check on the exact stone
- Is this VS2 diamond eye-clean face-up from about 10 inches away?
- In a face-up video, does the bow-tie flicker as the stone tilts, or stay a fixed dark band across the center?
- Will the ring setting use a protective V-tip prong or bezel to safeguard the delicate point?
- Can you show me the inscribed report number under a loupe before it is set?
