Some diamond shapes whisper. The marquise and the radiant shout.
Not in a way that is excessive or lacking refinement. But in the way that genuinely statement jewellery communicates: deliberately, confidently, and with the clear understanding that the piece is meant to be seen.
The marquise is the most dramatically elongated mainstream diamond shape available. The radiant is the hybrid shape that delivers brilliant sparkle in a rectangular form that the emerald cut does not. Both are genuinely underappreciated in India in 2026, which means buyers who choose them stand out from the round, oval, and cushion crowd in the best possible way.
The Marquise Cut: Maximum Presence Per Carat
The marquise cut is one of the oldest diamond shapes still in regular production, with origins attributed to the French court of Louis XV in the 18th century. Its characteristic outline, a long ellipse tapering to a pointed tip at each end, was reportedly inspired by the smile of the Marquise de Pompadour.
In practical modern terms, the marquise cut delivers the largest face-up surface area of any diamond shape per carat weight. A 1.00 carat marquise appears dramatically larger on the finger than a 1.00 carat round brilliant. For Indian buyers who want maximum visual diamond presence from a specific carat weight investment, the marquise is the most efficient choice available.
Marquise Cut Characteristics
Face-up size: the largest of any shape per carat, approximately 15 to 20 percent larger than a round brilliant of the same weight.
Length-to-width ratio: most marquise cuts fall between 1.75 and 2.25. The 1.85 to 2.10 range is the most elegant. Very elongated ratios above 2.25 look narrow on the finger. Very compact ratios below 1.75 look stubby.
Bowtie effect: marquise cuts can show a bowtie shadow across the centre. Assess the specific stone or view a video before purchasing. A moderate bowtie is acceptable; a severe bowtie significantly reduces beauty.
Pointed tips: both pointed ends require V-prong protection in any ring setting. This is non-negotiable for daily wear rings.
Best Settings for Marquise Cut
Five-prong or six-prong solitaire with V-prongs at both tips: the classic setting. Open sides allow maximum light entry. Both tips are protected.
East-west marquise setting: the marquise turned 90 degrees on the band so it sits across the finger horizontally. Increasingly popular in India in 2026 among buyers who want a recognisably unconventional engagement ring.
Halo setting: a ring of micro-pavé diamonds following the outline of the marquise creates a dramatic, elongated halo that amplifies the size illusion already inherent to the marquise shape.

The Radiant Cut: Brilliant Sparkle in a Rectangular Form
The radiant cut was developed in the 1970s as an attempt to bring the full light performance of the round brilliant to a rectangular shape. While the emerald cut deliberately sacrifices sparkle for the step-cut hall-of-mirrors effect, the radiant cut maximises brilliance through a complex modified brilliant faceting pattern applied to a rectangular outline.
The result is a diamond that looks like a brilliant from the inside but a rectangle from the outside. It sparkles like an oval but sits like a princess or emerald cut on the finger.
Radiant Cut Characteristics
Shape: available in rectangular (length-to-width ratio 1.15 to 1.35) and square (ratio 1.00 to 1.05) versions.
Faceting: the radiant uses between 62 and 70 facets in a pattern that blends elements of the round brilliant and emerald cut faceting, producing a crushed-ice appearance.
Brilliance: the radiant is among the most brilliant fancy shapes available. Its faceting efficiency is close to that of the round brilliant, making it the highest-performing rectangular shape in terms of light return.
Colour and clarity: the radiant is more forgiving than the emerald cut. VS2 clarity and G-H colour are entirely appropriate.
Radiant vs Princess: How to Choose
Both are brilliant-faceted square-to-rectangular shapes with similar face-up sizes and price points.
Princess cut has sharp 90-degree corner points that require V-prong protection. Radiant cut has cut corners (bevelled) that are structurally safer and do not require V-prongs.
Princess cut faceting produces a more structured sparkle pattern. Radiant cut faceting produces a more uniform crushed-ice sparkle.
If the sharp corner points and more structured geometry are the appeal, choose princess. If maximum sparkle in a rectangular shape without the corner vulnerability is the priority, choose radiant.
Radiant vs Emerald: The Fundamental Choice
Both are rectangular shapes with cut corners and similar silhouettes. The difference is everything inside the stone.
Emerald cut: step-cut faceting, hall-of-mirrors effect, restrained drama, requires higher clarity and colour grades.
Radiant cut: brilliant faceting, maximum sparkle, more forgiving of clarity and colour, best for buyers who want rectangular shape with round brilliant light performance.
Best Settings for Radiant Cut
Four-prong solitaire with standard prongs at the cut corners: the cut corners of a radiant are already structurally safer than princess cut corner points. A simple four-prong rectangular solitaire in white gold is the most elegant radiant cut setting.
Halo setting: a round brilliant halo surrounding a radiant cut creates interesting contrast of brilliant circular sparkle framing a rectangular centre stone.
Three-stone setting: a radiant centre flanked by two smaller trapezoidal or half-moon side stones creates a sophisticated three-stone configuration.

Marquise vs Radiant: Which Should You Choose?
Choose the marquise if: you want the maximum face-up size per carat of any shape, you want the most dramatic elongating effect on the finger, and you are comfortable with the V-prong tip requirement and the bowtie check.
Choose the radiant if: you want a rectangular brilliant-cut shape that sparkles like a round, you prefer cut corners without sharp tips, and you want the closest thing to round brilliant light performance in a non-round shape.
Frequently Asked Questions
Does the marquise cut always show a bowtie?
Yes, all marquise cuts have some degree of bowtie, as do all elongated brilliant cuts. The severity varies significantly between stones. A light or moderate bowtie is acceptable. A severe bowtie is clearly visible and should be avoided. Always view the specific stone before purchasing.
Is a radiant cut the same as a princess cut?
No. Both are rectangular or square brilliant-cut shapes but they are distinct cuts. The princess has sharp pointed corners and a specific faceting pattern. The radiant has cut corners and a modified brilliant faceting that produces a crushed-ice sparkle. They have different silhouettes, different setting requirements, and different visual textures.
Which finger shape does the marquise suit best?
The marquise is the most flattering shape for shorter or wider fingers because its extreme elongation creates the strongest finger-lengthening effect of any diamond cut.
Is the radiant cut good for daily wear?
Yes. The cut corners of the radiant make it structurally safer for daily wear than the sharp-corner princess cut. The radiant in a standard four-prong setting is entirely appropriate for continuous daily wear.
The Bottom Line
The marquise and radiant are two of the most underappreciated diamond shapes in India. Both deliver strong brilliance, both are priced below round brilliants of equivalent specification, and both create a distinctly personal jewellery choice.
