3.00 ct Oval Diamond

What reads well

• A 1.40:1 length-to-width ratio sits in the classic oval range.
• Face-up spread (11.35 × 8.08 mm) is typical or better for a 3.00 ct oval.
• Table 63% and depth 61.7% fall in the typical oval range.
• Excellent polish and symmetry, the top finish grades.
• No fluorescence: no haze risk to weigh.

What deserves a closer look

• SI2 is often not eye-clean in an oval; view an image or video of this exact stone.
• Thick to very thick girdle: a thick girdle carries hidden weight and can reduce face-up size (thicker points are common in fancy shapes).
• Feathers are listed: check the plot for any that reach the girdle or surface, which matters for durability.
• I color in a 3.00 ct oval may show some warmth, especially at the tips.
• Screening only: for this oval, check images or video of the exact stone for the bow-tie (a dark band across the centre) and whether both ends look even.

The reading, field by field

Table · Ideal

At 63%, the table sits within the typical 53–63% range for an oval, balancing brightness with fire.

Total depth · Ideal

61.7% is within the typical 58–63.5% range for an oval, keeping weight where it contributes to face-up size and light return.

Length-to-width · Ideal

A 1.4:1 outline is within the classic 1.3–1.5:1 range for an oval.

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 · Closer look

Thick to very thick, faceted: a thick girdle carries weight in the rim, so the stone can face up a little smaller for its carat weight. It is durable, though.

Culet · Ideal

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

Color · Favorable

I may show slight warmth at the tips of an oval, especially next to white metal. Yellow or rose gold tends to complement it.

Clarity · Closer look

SI2: inclusions may be visible to the eye. Confirm with images or video before buying.

Fluorescence · Ideal

None: no meaningful effect on appearance.

What to check on the exact stone

• Does the feather reach the outer edge where a setting prong could put pressure on it?
• Is this SI2 diamond eye-clean face-up from about 10 inches away?
• In a face-up video, does the bow-tie flicker as the stone tilts, or stay a fixed dark band across the center?
• Can you show me the inscribed report number under a loupe before it is set?
