The diamond industry, a sector built on tradition and timelessness, is experiencing a profound and exciting transformation. The century-long reign of the round brilliant cut, while far from over, is now sharing the spotlight with a dynamic and increasingly popular category: fancy shaped diamonds. This shift is most pronounced in the luxury segment of 2 carats and larger, where elongated cuts are not just a trend but a powerful market force redefining consumer preferences and value propositions.

For decades, the round brilliant was the undisputed king, prized for its unparalleled brilliance and fire. However, contemporary buyers, armed with more information and a stronger desire for individual expression, are driving a decisive move towards unique silhouettes. While rounds continue to dominate in overall volume, their pricing particularly for stones under 1 carat faces significant pressure. In stark contrast, elongated fancy shapes like Ovals, Marquises, Radiants, and Cushions are demonstrating remarkable resilience and growth, with discerning buyers willing to pay substantial premiums for exceptional stones.

This analysis will explore the data driving this shift, the psychological factors behind it, the broader industry context, and the critical opportunities it presents for retailers and collectors alike. Understanding this movement is essential for anyone looking to succeed in the modern diamond market.

Decoding the Market Data –

The current market landscape is characterized by a clear divergence. Recent reports from major international diamond shows, including Hong Kong, highlight a telling pattern: sluggish movement for smaller round brilliants (up to 1 carat) but vibrant, sustained demand for larger stones (2 carats and above) and, most notably, for fancy shapes and fancy colors.

Let's break down the performance of key elongated shapes:

The Marquise Cut: Reigning Supreme in Price

The Marquise cut, with its distinctive navette (boat-like) shape, currently holds the title of the most expensive fancy shape. This isn't accidental. It results from a perfect storm of limited supply and intense demand. The cut requires a specific type of rough diamond crystal to yield a well-proportioned stone without excessive weight loss.

This inherent rarity, combined with its strong appeal to retailers designing statement pieces and collectors seeking unique assets, has propelled its value. As with many fancy shapes, the quality of the cut is paramount; a poorly executed marquise can appear unbalanced or contain undesirable bow-tie effects.

The Elongated Cushion:

The Cushion cut, a timeless shape known for its soft, romantic appeal, has evolved. While square cushions remain popular, the market is showing a distinct preference for their elongated counterparts. Long Cushions are enjoying a significant 20% to 25% premium over square versions. This premium is a direct reflection of their elegant, flattering proportions on the finger and their superior rarity.

The cutting process for a long cushion is more challenging, as it requires the cutter to prioritize shape and face-up size over maximum yield from the rough, making high-quality examples highly sought-after.

The Oval Cut:

The Oval cut has become a powerhouse in the market, particularly within the United States. It strikes a perfect balance between classic brilliance (sharing a similar faceting pattern to the round brilliant) and a modern, elongated silhouette. Demand is most robust in the D–I color and VS–SI clarity range, appealing to a broad audience.

Due to this sustained popularity, premium ovals now command prices 5% to 10% higher than comparable Pear-shaped diamonds. Their ability to appear larger than a round of the same carat weight makes them a perennial favorite for engagement rings.

The Long Radiant and Emerald Cut:

Long Radiant cuts, with their trimmed corners and brilliant faceting, and Emerald cuts, with their classic step-cuts and hall-of-mirrors effect, are exceptionally difficult to source in high quality. Their attractiveness lies in their clean, architectural lines and the skill required to cut them well. A poorly cut emerald cut, for instance, will reveal inclusions and lack luster, whereas a superior cut exhibits unparalleled clarity and elegance. This scarcity of well-executed stones makes them incredibly attractive to buyers seeking a blend of modernity and vintage inspiration.

The "Why" Behind the Trend –

The movement towards elongated cuts is not a random fluctuation; it is rooted in fundamental shifts in consumer behavior and aesthetic preferences.

The Perception of Size and Value -

The most immediate advantage of an elongated diamond is optical. Because their surface area is distributed lengthwise, shapes like ovals and marquises have a larger face-up appearance than a round brilliant of the same carat weight. This creates immense perceived value for the buyer, who feels they are getting a more substantial-looking centerstone for their investment.

The Gemological Institute of America (GIA) notes that a diamond's cut grade and proportions are the most critical factors influencing its face-up size and beauty, a principle where elongated shapes excel - GIA.edu on How Cut Affects a Diamond's Face-Up Size

The Drive for Individuality and Exclusivity -

Modern consumers, especially millennials and Gen Z, prioritize uniqueness and self-expression. A round brilliant diamond, while beautiful, is a common choice. An elongated fancy shape serves as a declaration of individual style. It signifies a conscious decision to move beyond the conventional. This desire for exclusivity is compounded by the genuine rarity of high-quality fancy shapes.

Modern Aesthetics and Design Flexibility -

Elongated cuts are perceived as fresh, contemporary, and artistic. They offer jewelers and designers unparalleled flexibility. These shapes can be set east-west for a ultra-modern look, placed vertically in a classic solitaire to elongate the finger, or surrounded by halos and intricate side stones for a vintage-inspired masterpiece. Their versatility makes them a favorite in both bridal and high-fashion jewelry collections.

The Broader Industry Context – Trade, Supply, and Seasonal Trends

To fully grasp the elongated diamond trend, one must view it within the wider global diamond pipeline, which is itself undergoing significant changes.

Global Trade Dynamics

Two key developments are poised to impact the flow of diamonds:

US-EU Tariff Removal: The United States has removed tariffs on polished diamonds imported from the European Union. This policy shift could facilitate greater access to diamonds cut by renowned European artisans, potentially increasing the supply of high-quality fancy shapes in the US market.

US-India Trade Talks: As the US and India two of the most critical players in the diamond manufacturing and retail sectors engage in trade discussions, the entire industry is watching closely. The outcomes could reshape sourcing strategies and supply chains for years to come.

Shifting Ownership and Supply Control -

At the source level, major changes are underway. Botswana, a leading diamond producer, has stated its intention to become the controlling shareholder of De Beers. Simultaneously, Angola is seeking a minority stake in the company. These moves signal a broader trend of producing nations asserting more significant control over their resources, which could influence the future availability and pricing of rough diamond categories ideally suited for elongated cuts.

Positive Holiday Season Forecast -

For retailers, the upcoming season brings optimistic projections. Mastercard SpendingPulse forecasts a +3.6% year-over-year growth in US holiday retail sales, with e-commerce leading the charge at +7.9%. Jewelry, being a traditional gift category, is expected to be a strong performer. This makes it imperative for retailers to align their inventory with high-demand categories like elongated fancy shapes. Buyers will be actively searching online for natural diamonds that reflect these trends.

The Sourcing Challenge and the CaratX Opportunity

The primary challenge for the industry is clear: sourcing well-proportioned, expertly cut elongated fancy diamonds is difficult. They command significant premiums precisely because they are rare. The cutting process is less standardized than for rounds, requiring immense skill to maximize beauty and minimize flaws like the "bow-tie effect" common in ovals and marquises.

This challenge, however, represents the greatest opportunity. The market is bifurcating: standard goods face price pressure, while exceptional fancy shapes, larger sizes, and fancy colors are gaining considerable ground.
