1.50 ct Radiant Diamond
79/100 · Considered
A balanced profile with a few questions to carry forward.
What reads well
- A 1.25:1 length-to-width ratio sits in the classic radiant range.
- VVS1 clarity: inclusions are not a practical visual factor.
- Very Strong blue fluorescence can make I color face up a touch whiter in daylight.
What deserves a closer look
- The depth 72.7% sits outside the typical radiant range.
- Face-up area is about 13% below typical radiants of this weight, suggesting hidden weight in depth.
- Very thick girdle: a thick girdle carries hidden weight and can reduce face-up size (thicker points are common in fancy shapes).
- I color in a 1.50 ct radiant may show some warmth, especially at the corners.
- 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.
The reading, field by field
- Table · Ideal
- At 65%, the table sits within the typical 60–70% range for a radiant, balancing brightness with fire.
- Total depth · Closer look
- 72.7% 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 1.25:1 outline is within the classic 1.2–1.5:1 range for a radiant.
- Polish · Favorable
- Very Good polish is a fine result; the difference from Excellent is rarely visible without magnification.
- Symmetry · Favorable
- Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.
- Girdle · Closer look
- Very thick: 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 corners of a radiant, especially next to white metal. Yellow or rose gold tends to complement it.
- Clarity · Ideal
- VVS1: inclusions, if any, are only visible under magnification.
- Fluorescence · Favorable
- Very Strong Blue fluorescence can make an I stone look whiter in daylight; it is rarely a problem at this color.
What to check on the exact stone
- With 72.7% depth, does this stone face up smaller than a typical 1.50 ct radiant?
- Does the feather reach the outer edge where a setting prong could put pressure on it?
- Can I view this stone in daylight to see if the blue fluorescence helps it look whiter?
- Can you show me the inscribed report number under a loupe before it is set?
