5.00 ct Round Brilliant Diamond

What reads well

• D color is in the colorless range.
• VVS1 clarity: inclusions are not a practical visual factor.
• No fluorescence: no haze risk to weigh.

What deserves a closer look

• The GIA cut grade is Good: the lab's own assessment points to less brightness and fire than its top tier.
• Crown 37.5° / pavilion 40.8° fall outside the pairing zone associated with strong light return.
• Depth 65.7% sits outside the preferred round range.
• Very thick girdle: a thick girdle carries hidden weight and can reduce face-up size.
• The diameter is small for 5.00 ct: weight is carried below the girdle rather than face-up.

The reading, field by field

Table · Ideal

At 59%, the table sits within the typical 53–59% range for a round brilliant, balancing brightness with fire.

Total depth · Closer look

65.7% is deeper than typical for a round brilliant (59.5–63%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests.

Crown angle · Closer look

A 37.5° crown is steeper than the typical 32–36° zone. Steep crowns can add fire, but only pair well with a slightly shallower pavilion.

Pavilion angle · Ideal

40.8° is inside the narrow 40.5–41.3° zone where the pavilion returns light most efficiently.

Polish · Ideal

Excellent polish is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.

Symmetry · Favorable

Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.

Girdle · Closer look

Very thick, faceted, 6.5%: 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 · Ideal

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

Clarity · Ideal

VVS1: inclusions, if any, are only visible under magnification.

Fluorescence · Ideal

None: no meaningful effect on appearance.

Cut grade · Closer look

Good 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 steep crown give lively fire without making the center look darker?
• With 65.7% depth, does this stone face up smaller than a typical 5.00 ct round?
• 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?
