3.00 ct Round Brilliant Diamond

What reads well

• The GIA Excellent cut grade corroborates the measured proportions.
• Excellent polish and symmetry, the top finish grades.
• VVS1 clarity: inclusions are not a practical visual factor.
• No fluorescence: no haze risk to weigh.
• Medium to slightly thick girdle balances durability and weight retention.

What deserves a closer look

• Crown 33° / pavilion 41.6° fall outside the pairing zone associated with strong light return.
• Table 62% sits outside the preferred round range.
• I color can show slight warmth in some settings, more so in white metal.

The reading, field by field

Table · Closer look

A 62% table is larger than typical for a round brilliant (53–59%). Large tables can read bright but flatter, with less fire and contrast.

Total depth · Closer look

59.3% is shallower than typical for a round brilliant (59.5–63%). That spreads the stone face-up but raises the risk of windowing — a glassy, see-through center.

Crown angle · Ideal

33° 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

Medium to slightly thick, faceted, 3.0%: a durable girdle thickness that doesn't hide meaningful weight.

Culet · Ideal

None: no visible culet facet when viewed face-up.

Color · Favorable

I may show slight warmth, especially next to white metal. Yellow or rose gold tends to complement it.

Clarity · Ideal

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

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.

What to check on the exact stone

• Does the center turn dark or lose sparkle when you tilt the diamond face-up?
• With a shallow 59.3% depth, can you see a glassy, see-through patch in the center?
• Does the large table look bright but flat, with less colored fire than you expected?
• Can you show me the inscribed report number under a loupe before it is set?
