The Carat Standard

GIA report 2235711831

4.00 ct Pear Diamond

64/100 · Character

Distinctive trade-offs that should be viewed deliberately.

What reads well

  • A 1.60:1 length-to-width ratio sits in the classic pear range.
  • Face-up spread (13.81 × 8.65 mm) is typical or better for a 4.00 ct pear.
  • Table 63% and depth 62.7% fall in the typical pear range.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • SI2 is often not eye-clean in a pear; view an image or video of this exact stone.
  • Clouds are referenced on the report; confirm the stone looks transparent rather than hazy.
  • Slightly thick to very thick girdle: a thick girdle carries hidden weight and can reduce face-up size (thicker points are common in fancy shapes).
  • Feathers are listed: check the plot for any that reach the girdle or surface, which matters for durability.
  • 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.

The reading, field by field

Table · Ideal
At 63%, the table sits within the typical 53–63% range for a pear, balancing brightness with fire.
Total depth · Ideal
62.7% 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 1.6:1 outline is within the classic 1.45–1.75:1 range for a pear.
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 · Closer look
Slightly thick to very thick, faceted: a thick girdle carries weight in the rim, so the stone can face up a little smaller for its carat weight. It is durable, though.
Culet · Ideal
None: no visible culet facet when viewed face-up.
Color · Favorable
J may show slight warmth at the point of a pear, especially next to white metal. Yellow or rose gold tends to complement it.
Clarity · Closer look
SI2: inclusions may be visible to the eye. Confirm with images or video before buying.
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?
  • Is this SI2 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?
  • Can you show me the inscribed report number under a loupe before it is set?
