1.50 ct Round Brilliant Diamond

87/100 · Refined

A strong, composed candidate on paper.

What reads well

Crown 36° with pavilion 40.8° sits in the well-regarded pairing zone for brightness and fire.
The GIA Excellent cut grade corroborates the measured proportions.
Excellent polish and symmetry, the top finish grades.
H color should face up white in most settings.
No fluorescence: no haze risk to weigh.

Clouds are referenced on the report; confirm the stone looks transparent rather than hazy.
Confirm this SI1 round brilliant is eye-clean from an image or video; the report plot shows where inclusions sit.
Surface-reaching characteristics are listed (cavity); check their position on the plot for durability.
Feathers are listed: check the plot for any that reach the girdle or surface, which matters for durability.
The report notes surface graining; these can soften transparency in some stones.

Table · Ideal: At 58%, the table sits within the typical 53–59% range for a round brilliant, balancing brightness with fire.
Total depth · Ideal: 62.8% is within the typical 59.5–63% range for a round brilliant, keeping weight where it contributes to face-up size and light return.
Crown angle · Ideal: 36° sits in the 32–36° zone where crown angles typically balance fire and brightness.
Pavilion angle · Ideal: 40.8° is inside the narrow 40.5–41.3° zone where the pavilion returns light most efficiently.
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 · Ideal: Medium to slightly thick, faceted, 4.0%: a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal: None: no visible culet facet when viewed face-up.
Color · Favorable: H is near-colorless and faces up white in most settings.
Clarity · Favorable: SI1 is often eye-clean in a round brilliant, but not always — check where the inclusions sit.
Fluorescence · Ideal: None: no meaningful effect on appearance.
Cut grade · Ideal: Excellent as issued by GIA, on GIA's own scale. The measured proportions above tell you more than the label.

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?
Is the surface opening protected by a prong, or could it catch lint and risk chipping?
Can you show me the inscribed report number under a loupe before it is set?
