1.58 ct Round Brilliant Diamond

90/100 · Refined

A strong, composed candidate on paper.

What reads well

Crown 33.5° / pavilion 41.6° fall outside the pairing zone associated with strong light return.

Table · Ideal: At 59%, 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: 33.5° sits in the 32–36° zone where crown angles typically balance fire and brightness.
Pavilion angle · Closer look: 41.6° is steeper than the narrow 40.5–41.3° zone. Deep pavilions can leak light through the sides and darken the center.
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: Slightly thick, faceted, 4.5%: a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal: None: no visible culet facet when viewed face-up.
Color · Ideal: F is in the colorless range and faces up white in any metal.
Clarity · Ideal: VVS2: inclusions, if any, are only visible under magnification.
Fluorescence · Favorable: Medium Blue fluorescence is rarely visible in normal lighting.
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 center turn dark or lose sparkle when you tilt the diamond face-up?
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?
