6.00 ct Round Brilliant Laboratory-Grown Diamond

What reads well

• The IGI Excellent cut grade corroborates the measured proportions.
• Excellent polish and symmetry, the top finish grades.
• E color is in the colorless range.
• VVS2 clarity: inclusions are not a practical visual factor.
• No fluorescence: no haze risk to weigh.

What deserves a closer look

• Crown 34.8° / pavilion 41.5° fall outside the pairing zone associated with strong light return.
• Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.

The reading, field by field

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

34.8° sits in the 32–36° zone where crown angles typically balance fire and brightness.

Pavilion angle · Closer look

41.5° 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): a durable girdle thickness that doesn't hide meaningful weight.

Culet · Ideal

Pointed: no visible culet facet when viewed face-up.

Color · Ideal

E is in the colorless range and faces up white in any metal.

Clarity · Ideal

VVS2: inclusions, if any, are only visible under magnification.

Fluorescence · Ideal

None: no meaningful effect on appearance.

Cut grade · Ideal

Excellent as issued by IGI, on IGI'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 this CVD diamond show any brown or gray undertone face-up in daylight?
• Can you show me the inscribed report number under a loupe before it is set?
