1.20 ct Princess Diamond
90/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 1.00:1 length-to-width ratio sits in the classic princess range.
- Face-up spread (5.74 × 5.72 mm) is typical or better for a 1.20 ct princess.
- Table 74% and depth 74.9% fall in the typical princess range.
- E color is in the colorless range.
- No fluorescence: no haze risk to weigh.
What deserves a closer look
- The report notes internal graining; these can soften transparency in some stones.
- Screening only: for this princess, check images or video of the exact stone for dark areas across the corners or a see-through centre.
The reading, field by field
- Table · Ideal
- At 74%, the table sits within the typical 63–74% range for a princess, balancing brightness with fire.
- Total depth · Ideal
- 74.9% is within the typical 64–75% range for a princess, keeping weight where it contributes to face-up size and light return.
- Length-to-width · Ideal
- A 1:1 outline is within the classic 1–1.05:1 range for a princess.
- Polish · Ideal
- Excellent polish is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
- Symmetry · Favorable
- Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.
- Girdle · Ideal
- Thick, polished: a durable girdle thickness that doesn't hide meaningful weight.
- Culet · Ideal
- None: no visible culet facet when viewed face-up.
- Color · Ideal
- E is in the colorless range and faces up white in any metal.
- Clarity · Ideal
- VVS2: inclusions, if any, are only visible under magnification.
- Fluorescence · Ideal
- None: no meaningful effect on appearance.
What to check on the exact stone
- Does the feather reach the outer edge where a setting prong could put pressure on it?
- With Very Good symmetry, are any facet junctions visibly misaligned?
- Can you show me the inscribed report number under a loupe before it is set?
