The global diamond market is undergoing a significant and exciting transformation. While the classic round brilliant cut has long been the undisputed king, a new era is dawning where fancy diamond shapes are not just gaining ground they are leading the charge in demand, liquidity, and price premiums.

This shift is most pronounced in diamonds of 2 carats and above, where buyers are increasingly seeking unique, personalized expressions of luxury and elegance. Driven by changing consumer tastes, celebrity influence, and a desire for stones that maximize visual size, elongated fancy cuts are redefining desirability. For industry insiders and consumers alike, understanding this trend is key to navigating the modern diamond landscape.

The Market Shift: Why Fancy Shapes Are Outperforming Rounds

For decades, the round brilliant cut was the default choice, prized for its unparalleled fire and brilliance. However, market analytics and dealer reports now consistently show that in the key size category of 2+ carats, elongated fancy shapes are moving faster and commanding stronger prices than rounds. This is a fundamental change in buyer psychology.

The primary driver is aesthetics. Elongated shapes, such as ovals and marquises, create an elegant, flattering effect on the finger, making the hand appear more slender and the diamond larger for its carat weight. This "size illusion" offers exceptional value. Furthermore, these shapes align with contemporary jewelry design trends that favor sleek, modern, and artistic lines over traditional symmetry.

According to the Gemological Institute of America (GIA), the cut of a diamond is the factor that most significantly affects its beauty and sparkle. The growing appreciation for fancy shapes underscores a more sophisticated consumer who understands that cut encompasses not just proportions but also personal style and silhouette.

Top-Performing Shapes -

1. The Marquise:

The marquise cut diamond, with its distinctive football-like shape and pointed ends, has surged to become the most expensive fancy shape on the market. This is due to a powerful combination of intense demand and critically limited supply.

High-quality marquises with excellent symmetry, clean bow-tie effect management, and superior length-to-width ratios (often between 1.85:1 and 2.1:1) are exceptionally scarce. Buyers captivated by its royal heritage and dramatic appearance are paying a premium, making it a highly liquid asset for sellers with access to quality stones.

2. The Oval:

The oval cut diamond continues to show remarkable strength, particularly in the United States market. The demand is highly specific: consumers are seeking well-proportioned, elongated ovals (ideal ratios between 1.35:1 and 1.5:1) in the D–I color range and VS–SI clarity grades.

A well-cut oval offers the brilliance of a round but with a more unique and elongated profile. Stones that meet these criteria remain incredibly easy to sell.

3. Long Cushions & Radiants:

Cushion cut diamonds have bifurcated in demand. While square cushions are steady, long cushion cuts (also called elongated or rectangular cushions) are experiencing feverish demand, selling at a 20-25% premium over their square counterparts.

Similarly, long radiant cuts, which blend the faceting of a round with the shape of an emerald are in short supply. These shapes offer a perfect blend of vintage charm and modern sparkle, appealing to a broad audience.

4. The Emerald Cut:

While not as frantic as marquise or oval, the emerald cut diamond maintains a strong, steady demand among buyers seeking "hall of mirror" clarity and a sophisticated, art-deco vibe. Its popularity in celebrity engagement rings has cemented its status. Performance is highly dependent on quality; due to its step-cut faceting, clarity and color are more visible, making premium grades essential.

Market Nuances & Weak Spots

The Indian Market Softening: Reports indicate a softening in prices for smaller (0.30–0.79 ct) ovals and pears in the Indian market. The notable exception is for rare, ideally proportioned long versions of these shapes, which continue to perform well. This highlights a global trend: quality and superior proportions are paramount.

The Princess Cut Struggle: In stark contrast to the elongated trend, the princess cut diamond remains one of the weakest-performing shapes. Movement is slow, and pricing is under pressure. This square shape, while brilliant, does not align with the current appetite for elongated silhouettes.

The Quality Divide: The market is creating a stark divide between premium and subpar stones. A well-cut fancy shape with excellent proportions, symmetry, and polish is a high-value, fast-moving asset.

Conversely, fancy shapes with poor proportions, bad symmetry, or awkward silhouettes are becoming nearly unsellable, often requiring deep discounts. As noted by industry analysts at Bain & Company in their annual diamond report, consumer discernment is at an all-time high, favoring quality over mere carat weight.

Frequently Asked Questions (FAQs)

Q1: Why are elongated fancy shapes more popular than rounds now? A: Elongated shapes like ovals and marquises offer a modern, elegant look that can make the finger appear longer and the diamond look larger per carat. They represent a move towards personalized, unique jewelry over traditional choices.

Q2: What does "long" or "elongated" mean for a cushion or radiant cut? A: It refers to the length-to-width ratio. A square cushion has a ratio close to 1.0:1. A "long cushion" typically has a ratio above 1.10:1, giving it a more rectangular appearance, which is currently in high demand.

Q3: Why are some fancy shapes hard to find? A: Cutting a high-quality fancy shape requires more skill from the cutter to optimize yield from the rough diamond crystal, which is often an irregular shape. For cuts like marquise, finding rough that can yield a stone with good proportions without significant weight loss is challenging, limiting supply.

Q4: Is the princess cut a bad investment? A: "Bad" is relative. Currently, market demand and liquidity for princess cuts are lower compared to elongated shapes. However, market trends are cyclical. A high-quality stone of any cut will always retain more value than a poorly cut one.

Q5: How important is cut quality for fancy shapes? A: It is the most critical factor. A poorly proportioned fancy shape can have fatal flaws like severe bow-ties (dark areas across the center) in ovals and marquises, or a dull, lifeless appearance. Premiums are paid exclusively for well-cut stones.
