3.00 ct Radiant Laboratory-Grown Diamond

What reads well

• A 1.45:1 length-to-width ratio sits in the classic radiant range.
• Excellent polish and symmetry, the top finish grades.
• E color is in the colorless range.
• VS1 clarity is typically eye-clean in a radiant.
• No fluorescence: no haze risk to weigh.

What deserves a closer look

• The table 58% sits outside the typical radiant range.
• Screening only: for this radiant, check images or video of the exact stone for the sparkle pattern (defined flashes or "crushed ice") and any dark or see-through corners.
• 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 · Favorable

A 58% table is smaller than typical for a radiant (60–70%). Smaller tables tend to favor fire over broad, flat brightness.

Total depth · Closer look

69% is deeper than typical for a radiant (61–68%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests.

Length-to-width · Ideal

A 1.45:1 outline is within the classic 1.2–1.5:1 range for a radiant.

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 to thick: 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 · Favorable

VS1 is typically eye-clean.

Fluorescence · Ideal

None: no meaningful effect on appearance.

What to check on the exact stone

• With 69% depth, does this stone face up smaller than a typical 3.00 ct radiant?
• 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?
