The Carat Standard

GIA report 6217976856

5.00 ct Emerald Diamond

50/100 · Investigate

The report asks for a more careful visual review.

What reads well

  • A 1.33:1 length-to-width ratio sits in the classic emerald cut range.
  • Face-up spread (10.88 × 8.19 mm) is typical or better for a 5.00 ct emerald cut.
  • Medium blue fluorescence can make J color face up a touch whiter in daylight.

What deserves a closer look

  • SI2 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.
  • Feathers are listed: check the plot for any that reach the girdle or surface, which matters for durability.
  • J color in a 5.00 ct emerald cut may show some warmth, especially at the corners.
  • 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 · Favorable
A 59% table is smaller than typical for an emerald cut (60–69%). Smaller tables tend to favor fire over broad, flat brightness.
Total depth · Closer look
69.9% 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 1.33:1 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
Thick: a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal
None: no visible culet facet when viewed face-up.
Color · Favorable
J may show slight warmth at the corners of an emerald cut, 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 · Favorable
Medium Blue fluorescence is rarely visible in normal lighting.

What to check on the exact stone

  • With 69.9% depth, does this stone face up smaller than a typical 5.00 ct emerald?
  • 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?
