The Carat Standard

GIA report 2458955896

1.01 ct Pear Diamond

79/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

  • Face-up spread (8.04 × 5.65 mm) is typical or better for a 1.01 ct pear.
  • Excellent polish and symmetry, the top finish grades.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • A 1.42:1 length-to-width ratio is outside the classic pear range; the outline will look more compact than typical.
  • Clouds are referenced on the report; confirm the stone looks transparent rather than hazy.
  • Confirm this SI1 pear is eye-clean from an image or video; the report plot shows where inclusions sit.
  • A 64.4% depth is on the deep side for a pear; deeper pavilions are associated with a stronger bow-tie and hidden weight.
  • 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 60%, the table sits within the typical 53–63% range for a pear, balancing brightness with fire.
Total depth · Closer look
64.4% is deeper than typical for a pear (58–64%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests and may show a stronger bow-tie.
Length-to-width · Favorable
A 1.42:1 outline is squarer than the classic 1.45–1.75:1 range for a pear — a matter of taste, but worth seeing in person.
Polish · Ideal
Excellent polish is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
Symmetry · Ideal
Excellent symmetry is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
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 · Closer look
K shows visible warmth. It suits buyers who like a softer, warmer look, and pairs best with yellow or rose gold.
Clarity · Favorable
SI1 is often eye-clean in a pear, but not always — check where the inclusions sit.
Fluorescence · Ideal
None: no meaningful effect on appearance.

What to check on the exact stone

  • With 64.4% depth, does this stone face up smaller than a typical 1.01 ct pear?
  • Does the diamond look crisp and transparent in natural light, or is there any milky haze?
  • Does the feather reach the outer edge where a setting prong could put pressure on it?
  • Can you show me the inscribed report number under a loupe before it is set?
