The diamond industry is witnessing one of the most significant transformations in modern history. For decades, theround brilliant cutreigned supreme as the undisputed king of diamonds. But 2026 has ushered in a dramatic shift fancy-shaped diamonds are stealing the spotlight, and the trend shows no signs of slowing down.
Buyers are increasingly gravitating toward longer, elegant shapes, particularly in 2-carat and larger sizes. This analysis explores the current state of the fancy-shaped diamond market, regional demand patterns, and what this means for buyers and sellers alike.
The Rise of Fancy Shapes:
The global diamond market is undergoing a fundamental realignment. According to theGemological Institute of America (GIA), the world's foremost authority on diamonds, GIA recognizes more than 40 distinct categories of fancy-shaped diamonds, each with unique characteristics and appearance qualities. This diversity gives consumers unprecedented choice and personalization options.
Market data from leading industry analysts confirms that long fancy shapes such as Ovals, Marquises, and Emeralds are consistently outperforming rounds, particularly in the 2-carat and larger categories. This represents a reversal of decades of round-centric pricing and consumer preference.
The shift is driven by several converging factors:
The "Illusion of Size" – Elongated shapes distribute carat weight along a larger table, creating a bigger visual footprint than a round diamond of the same weight.
Contemporary Aesthetics – Modern jewelry design has moved toward sleek, minimalist settings that complement elongated diamonds perfectly.
Celebrity Influence – High-profile engagements featuring fancy shapes have dramatically increased consumer awareness and demand.
Individuality – Today's consumers seek unique, personalized pieces that express their individual style rather than following tradition blindly.
Shape-by-Shape Analysis:
Oval Diamonds –
TheOval cuthas emerged as the strongest-performing fancy shape in the market. According to Whiteflash sales data,Oval diamondsrepresented 11.6% of sales, making them the most popular non-round option.
Search data reveals thatOvalsearches rose from 1,877,686 in 2024 to 2,669,103 in 2025, representing a staggering +42.1% increase. The US market shows a robust appetite for elongated Ovals of good shape and quality in the D-I color and VS-SI clarity categories.
Oval cutstypically command a 5% to 10% premium over comparablePear-shaped diamondsin the US market, reflecting their superior demand.
Marquise –
TheMarquise cuthas made a spectacular comeback. Its boat-like silhouette with pointed ends creates an exceptional finger-lengthening effect that has captivated royalty and celebrities for centuries.
However,high-quality Marquises are now the most expensive fancy shape on the market due to critically limited supply. Producing a well-proportionedMarquiseis notoriously difficult the rough-diamond yield is lower than for many other fancies, and achieving perfect symmetry without a distracting bow-tie effect requires exceptional craftsmanship.
According to the GIA's research on fancy-shaped diamonds, observers consistently dislike diamonds with prominent windowing, and the "bow tie" effect remains a key consideration in marquise quality assessment.
Sellers holding 2.00+ carat, D-F color Marquises with excellent symmetry are currently in the driver's seat for price negotiations.

Emerald Cut –
TheEmerald cut, with its clean, sophisticated lines and step-cut facets, continues to attract buyers seeking understated elegance. Unlike brilliant cuts that maximize sparkle, theEmeraldcut offers a hall-of-mirrors effect that emphasizes clarity and purity.
Like other elongated fancies,Emerald cuts in 2-carat and larger sizes are outperforming rounds. However, finding well-cut specimens with good proportions and minimal inclusions is increasingly difficult, supporting premium pricing for high-quality stones.

Long Cushion –
TheCushion cutis being reimagined for contemporary tastes.Long Cushions(rectangular cushions with elongated proportions) are currently one of the hottest segments in the fancy diamond market.
According to market data,Long Cushionsare easy to sell and currently trading at a 20% to 25% premium over square Cushion diamonds. This premium reflects the market's willingness to pay for the unique blend of vintage romance and modern, elongated proportions that this cut offers.
The demand for elongated proportions has turned specific cuts into premium assets, withLong Radiants and Long Cushions in critically short supply.

Princess Cut –
ThePrincess cuthas experienced a long period of weakness, with the market remaining relatively slow for this shape. However, there are signs of renewed demand emerging after this extended slump, although prices remain relatively low compared to other fancy shapes.
Industry observers note that the princess cut's square silhouette may be benefiting from the broader shift toward unique, individualized choices. While it hasn't recovered to the levels of elongated fancies, the renewed interest suggests potential opportunity for buyers seeking value.

Antique Cuts –
Antique and vintage-inspired diamond cuts are experiencing a remarkable resurgence. Demand for old-cut diamonds has risen sharply in the past five years, driven by their distinct broad facets, shallower proportions, and vintage appeal.
Interest surged after football star Travis Kelce proposed to Taylor Swift with an old-cut diamond engagement ring in August 2025. Searches for "old mine cut" reportedly rose almost 10,000% following the engagement news.
The antique cushion has become one of the most requested diamond shapes of 2026. As one designer notes, "People are over perfect" the irregular, characterful nature of antique cuts appeals to consumers seeking authenticity and individuality.
The trend represents a significant cultural shift, with vintage-inspired settings becoming one of the strongestengagement ringtrends of 2026, replacing the sleek, minimalist designs that dominated much of the last decade.
The Quality Imperative:
The current market has created a clear hierarchy of value for fancy diamonds, and quality has never been more important. According to multiple market reports, very well-cut fancy shapes are difficult to find and commanding premiums, while fancies with bad proportions have become highly illiquid.
The GIA emphasizes that cut is perhaps the most crucial of the 4Cs (Cut, Color, Clarity, and Carat Weight). A diamond's cut determines how well it reflects light, making it the most important factor in a stone's brilliance and fire.
For fancy shapes, the quality challenge is even more complex. As GIA research demonstrates, the cut grading methods applied to round brilliants cannot be simply transferred to fancy-shaped diamonds. Each fancy shape merits its own tailored approach to cut quality grading, taking into account its unique set of visual attributes.
For buyers and sellers, this means:
Well-cut fancy diamonds command significant premiums.
Poorly proportioned stones are increasingly difficult to sell.
Quality, not just carat weight, drives value.

Hong Kong –
Hong Kong buyers show a strong preference for 2-carat and larger diamonds, particularlyOvals,Marquises, andEmeraldcuts. High-quality fancy shapes are in short supply, supporting premium pricing.
The June Hong Kong Jewellery & Gem Asia show reflected a solid market for premium jewelry, gemstones, and 5-carat+ diamonds. Demand for 3-carat and above remains stable.
Belgium –
Trading in Belgium is picking up after the summer holiday, with a positive outlook for the upcoming season. Shortages are supporting prices, with solid interest in large diamonds, particularly 5-carat and larger stones, and fancy shapes in 2 to 4 carats, G-H color, VVS1-VS2 clarity.
Israel –
The Israeli market remains quiet as the summer vacation period comes to an end. Retailers are mainly selling memo goods and waiting to replenish inventory.
Supply Constraints:
Natural diamond supply is at multi-decade lows, creating a supportive environment for premium pricing. Global natural diamond supply was estimated at just over 100 million carats in 2025, marking the lowest annual output since 1992. In 2026, supply is forecast to only moderately rebound to around 105 million carats.
De Beers has cut 2026 production guidance to 21-26 million carats, down from a previous 26-29 million carats. The company is estimated to be producing at as much as 35% under capacity.
This supply discipline, combined with strong demand for high-quality fancy shapes, is supporting premium pricing for well-cut stones. De Beers forecasts global rough diamond production will fall from around 105 million carats in 2026 to 96 million carats by 2030.

Frequently Asked Questions -
1. Why are fancy-shaped diamonds becoming more popular?
Fancy shapes offer greater individuality, superior finger coverage (the "illusion of size"), and complement modern minimalist jewelry designs. Celebrity influence has also significantly boosted demand.
2. Which fancy shape is the most expensive?
The Marquise cut is currently the most expensive fancy shape due to critically limited supply of high-quality stones. Producing a well-proportioned Marquise requires exceptional craftsmanship and results in lower rough-diamond yield.
3. Why do Long Cushions command a premium over square Cushions?
Long Cushions are currently trading at a 20-25% premium over square Cushions because elongated proportions are in high demand while supply is limited.
4. Are antique-cut diamonds a good investment?
Antique cuts have seen sharply rising demand over the past five years. Genuine antique stones are finite and impossible to replicate exactly, making them both scarce and increasingly valuable.
5. How important is cut quality for fancy-shaped diamonds?
Extremely important. Well-cut fancy diamonds command significant premiums, while poorly proportioned stones are highly illiquid. The GIA notes that cut is perhaps the most crucial of the 4Cs.
6. Is the Princess cut making a comeback?
After a long period of weakness, the Princess cut is showing signs of renewed demand, although prices remain relatively low. This may represent a value opportunity for buyers.
