1.50 ct Heart Laboratory-Grown Diamond

What reads well

• A 0.92:1 length-to-width ratio sits in the classic heart range.
• Face-up spread (7.21 × 7.87 mm) is typical or better for a 1.50 ct heart.
• Excellent polish and symmetry, the top finish grades.
• E color is in the colorless range.
• VS1 clarity is typically eye-clean in a heart.

What deserves a closer look

• The stated 56.3% depth does not match the measurements (about 61.4%). Check the report data.
• The table 65% sits outside the typical heart range.
• A 56.3% depth is shallow for a heart; check images for a see-through window in the centre.
• Thick to very thick girdle: a thick girdle carries hidden weight and can reduce face-up size (thicker points are common in fancy shapes).
• Screening only: for this heart, check images or video of the exact stone for even lobes, a crisp cleft and a point that lines up below it.

The reading, field by field

Table · Closer look

A 65% table is larger than typical for a heart (53–63%). Large tables can read bright but flatter, with less fire and contrast.

Total depth · Ideal

56.3% is within the typical 56–63% range for a heart, keeping weight where it contributes to face-up size and light return.

Length-to-width · Ideal

A 1.09:1 outline is within the classic 0.9–1.1:1 range for a heart.

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

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 the large table look bright but flat, with less colored fire than you expected?
• Is extra carat weight trapped in the thick girdle rim where it does not add finger presence?
• 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?
