The Carat Standard

GIA report 1557995066

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?
