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?
