The Carat Standard

GIA report 6525543930

1.20 ct Emerald Diamond

77/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

  • A 1.40:1 length-to-width ratio sits in the classic emerald cut range.
  • G color should face up white in most settings.

What deserves a closer look

  • SI1 in an emerald cut: the open step-cut table makes inclusions easier to see. View an image or video of this exact stone.
  • Clouds are referenced on the report; confirm the stone looks transparent rather than hazy.
  • Medium yellow fluorescence can make the stone look warmer in daylight.
  • The report notes surface graining; these can soften transparency in some stones.
  • Screening only: for this emerald cut, check images or video of the exact stone for the "hall of mirrors" step pattern, any see-through window under the table and clean corners.

The reading, field by field

Table · Ideal
At 61%, the table sits within the typical 60–69% range for an emerald cut, balancing brightness with fire.
Total depth · Closer look
69.6% is deeper than typical for an emerald cut (60–69%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests.
Length-to-width · Ideal
A 1.4:1 outline is within the classic 1.3–1.5:1 range for an emerald cut.
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
Slightly thick to thick, polished: a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal
None: no visible culet facet when viewed face-up.
Color · Favorable
G is near-colorless and faces up white in most settings, though an emerald cut can show a hint of warmth at the corners.
Clarity · Closer look
SI1 in a step cut often shows inclusions through the open table. Confirm eye-cleanliness with images or video.
Fluorescence · Closer look
Medium Yellow fluorescence can make the stone look slightly warmer in daylight.

What to check on the exact stone

  • With 69.6% depth, does this stone face up smaller than a typical 1.20 ct emerald?
  • Does the diamond look crisp and transparent in natural light, or is there any milky haze?
  • With open step facets, is the center completely eye-clean without any visible dark marks?
  • Can you show me the inscribed report number under a loupe before it is set?
