The Carat Standard

GIA report 6425203205

3.00 ct Round Brilliant Diamond

90/100 · Refined

A strong, composed candidate on paper.

What reads well

  • The GIA Excellent cut grade corroborates the measured proportions.
  • Excellent polish and symmetry, the top finish grades.
  • VS2 clarity is typically eye-clean in a round brilliant.
  • No fluorescence: no haze risk to weigh.
  • Medium to slightly thick girdle balances durability and weight retention.

What deserves a closer look

  • I color can show slight warmth in some settings, more so in white metal.

The reading, field by field

Table · Closer look
A 60% 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 · Ideal
60.3% 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
32° sits in the 32–36° zone where crown angles typically balance fire and brightness.
Pavilion angle · Closer look
41.4° 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, 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
I may show slight warmth, especially next to white metal. Yellow or rose gold tends to complement it.
Clarity · Favorable
VS2 is typically eye-clean.
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?
  • Does the large table look bright but flat, with less colored fire than you expected?
  • 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?
