1.50 ct Round Brilliant Diamond

What reads well

• H color should face up white in most settings.
• VVS1 clarity: inclusions are not a practical visual factor.
• No fluorescence: no haze risk to weigh.

What deserves a closer look

• Crown 38.5° / pavilion 40.2° fall outside the pairing zone associated with strong light return.
• Depth 64.9% sits outside the preferred round range.

The reading, field by field

Table · Ideal

At 56%, the table sits within the typical 53–59% range for a round brilliant, balancing brightness with fire.

Total depth · Closer look

64.9% is deeper than typical for a round brilliant (59.5–63%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests.

Crown angle · Closer look

A 38.5° crown is steeper than the typical 32–36° zone. Steep crowns can add fire, but only pair well with a slightly shallower pavilion.

Pavilion angle · Closer look

40.2° is shallower than the narrow 40.5–41.3° zone. Shallow pavilions can let light pass straight through, looking glassy.

Polish · Favorable

Very Good polish is a fine result; the difference from Excellent is rarely visible without magnification.

Symmetry · Favorable

Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.

Girdle · Favorable

Slightly thick to thick, faceted, 5.0%: durable, on the thicker side for a round brilliant, so a little weight sits in the rim.

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 · Ideal

VVS1: inclusions, if any, are only visible under magnification.

Fluorescence · Ideal

None: no meaningful effect on appearance.

Cut grade · Favorable

Very Good as issued by GIA, on GIA's own scale. The measured proportions above tell you more than the label.

What to check on the exact stone

• Does a gray ring or glassy patch show around the center when you look straight down?
• With 64.9% depth, does this stone face up smaller than a typical 1.50 ct round?
• 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?
