1.58 ct Radiant Laboratory-Grown Diamond

What reads well

• A 1.47:1 length-to-width ratio sits in the classic radiant range.
• Face-up spread (8.64 × 5.86 mm) is typical or better for a 1.58 ct radiant.
• Table 62% and depth 64.5% fall in the typical radiant range.
• Excellent polish and symmetry, the top finish grades.
• E color is in the colorless range.

What deserves a closer look

• 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 · Ideal

At 62%, the table sits within the typical 60–70% range for a radiant, balancing brightness with fire.

Total depth · Ideal

64.5% is within the typical 61–68% range for a radiant, keeping weight where it contributes to face-up size and light return.

Length-to-width · Ideal

A 1.47:1 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

Medium: 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

• 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?
