The diamond industry has entered a period of remarkable transformation. While the overall market sentiment remains cautious due to macroeconomic pressures and geopolitical tensions, a fascinating polarization is occurring within the trade.Round brilliant diamondslong considered the gold standard of diamond cutting are no longer the sole protagonists of theluxury jewelrynarrative.
Instead, elongated fancy shapes are commanding attention, premiums, and increasingly, the purchasing power of discerning buyers across the globe.
According to the latest market intelligence, the diamond trade's trusted bulletin since 1980, long fancy shapes such asovals,marquises, andemeraldsare moving exceptionally well in the 2-carat-and-larger segment. This is not a fleeting trend, it represents a fundamental shift in how consumers, retailers, and diamantaires perceive value, beauty, and rarity in natural diamonds.
In this guide, we will explore the full spectrum of fancy-shaped diamond market dynamics in 2026, from shape-by-shape performance metrics to country-level demand shifts, and provide actionable insights for both B2B traders and B2C buyers.
Why Fancy Shapes Are Winning in 2026 -
The Supply-Demand Equation -
The fundamental driver behind the fancy shape premium is simple economics: scarcity of quality. Whileround brilliant diamondsbenefit from highly standardized cutting processes and abundant supply across most size ranges, well-cut fancy shapes particularly in the 2-carat-plus category are genuinely difficult to source.
Fancies with bad proportions illiquid". This indicates a two-tier market emerging within fancy shapes themselves: exceptional cuts command significant premiums, while poorly proportioned stones struggle to find buyers at any price point.
The Aesthetics of Elongation -
Beyond supply dynamics, there is a clear aesthetic preference driving demand. Elongated shapes create the illusion of greater size and finger coverage, a highly desirable attribute forengagement ringsand statement pieces. This optical advantage makes a 2-carat oval or marquise appear visually larger than a comparable round brilliant of the same weight.
The data supports this preference emphatically. According to industry sales data,ovalsaccounted for 11.6% of diamond sales in 2026, making them the leading fancy shape, followed bypearsat 5.9%,emeraldsat 5.7%,radiantsat 5.3%, andcushionsat 3.7%.
Shape-by-Shape Market Analysis -
Oval Diamonds:
Oval diamondshave cemented their position as the most commercially significant fancy shape. The United States market shows particular strength for elongated ovals of good shape and quality in D-I color and VS-SI clarity categories.
In Antwerp, oval and marquise shapes in larger sizes are also moving nicely, reflecting the global nature of this demand. For retailers looking to stock high-performing fancy shapes,explore our curated selection of oval diamonds on CaratXto find stones that meet these demanding specifications.
Key insight: The premium for well-proportioned ovals remains strong, but poorly cut stones are increasingly difficult to sell. Focus on length-to-width ratios between 1.35 and 1.50 for optimal marketability.
Marquise Diamonds:
Themarquise cutwith its distinctive boat-shaped silhouette and regal heritage has become the most expensive fancy shape on the market in 2026. This premium is driven entirely by supply constraints. High-quality marquises, particularly in larger sizes and with excellent symmetry, are in critically short supply.
"High-quality Marquises,long Radiantsandlong Cushionsin short supply. Marquise most expensive fancy shape". Sellers holding 2.00+ carat marquises in D-F color with excellent symmetry are currently in the driver's seat for price negotiations.
For buyers seeking toacquire investment-grade marquise diamonds, timing and access to inventory are critical. The scarcity is not expected to resolve in the near term, as manufacturers have cut production sharply, further reducing inventory of 2-carat and larger goods.
Emerald Cut Diamonds:
Theemerald cutprized for its hall-of-mirrors brilliance and architectural step facets presents a more nuanced market picture. While long emerald cuts are performing well in the 2-carat-plus segment, demand has cooled in the United States market specifically.
This does not mean emerald cuts are struggling rather, the market is segmenting. High-quality emerald cuts with excellent clarity (ideally VS1 or better, as the step cutting makes inclusions more visible) continue to attract discerning buyers. For retailers,sourcing certified emerald cut diamondswith GIA reports remains essential for maximizing sell-through.
Long Cushion Diamonds:
Cushion cutshave undergone an interesting evolution. The elongated, "long" cushion distinct from its square counterpart is trading at a 20% to 25% premium over square cushion diamonds. This premium reflects both aesthetic preference and relative scarcity.
However, market dynamics are shifting. Recent reports indicate that long cushions have become "softer than before due to oversupply," even as radiant and old-cut goods see sustained demand. This suggests that while the long cushion premium persists, buyers should exercise caution and focus on stones with exceptional cut quality and proportions.
Long Radiant Diamonds:
Radiant cutscombine the brilliance of round diamonds with the elegant silhouette of emerald cuts, featuring trimmed corners that create a distinctive octagonal shape. Long radiants of good quality are currently difficult to find, placing them in the same supply-constrained category as high-quality marquises.
For B2B buyers looking topurchase radiant cut diamonds in bulk, establishing direct relationships with manufacturers who specialize in fancy shapes is essential. The CaratX marketplace connects buyers with verified suppliers across 18+ countries, providing access to inventory that may not be available through traditional channels.
Princess Cut Diamonds:
After an extended period of weakness, there are signs of demand improvement forprincess cuts.Rapaport reports "demand for Princesses after long period of weakness; prices remain low". This is encouraging news for a shape that had fallen out of fashion in recent years.
Industry analysts remain cautious, however. JCK Online notes that while Rapaport has mentioned an uptick inprincessdemand multiple times in recent months, the evidence remains anecdotal. For retailers considering princess cut inventory, the current low prices may represent an opportunity but only for those who can effectively market the shape's unique combination of brilliance and value.
Antique Cuts:
The most intriguing development in the 2026 fancy shape market is the surge in demand for antique cuts old mine cuts, old European cuts, and other vintage-inspired styles. Rapaport's market commentary repeatedly describes antique cuts and styles as "hot".
This trend has been accelerated by high-profile celebrity engagements, with searches for antique diamond engagement rings surging significantly. A one-carat old mine cut diamond can command prices well above comparable modern cuts due to its scarcity and unique character.

Global Market Dynamics: A Country-by-Country Analysis
United States:
The United States remains the primary driver of fancy shape diamond demand globally. Bridal demand is steady for 1.50-carat and larger diamonds, with pears, radiants, marquises, and antique shapes performing particularly well.
According to De Beers' latest consumer research, natural diamond sales at U.S. independent jewelers increased 4% in Q4 2025 and 9% in Q1 2026, with demand concentrated in stones of 1 carat or more. While bridal purchases account for 45% of Gen Z acquisitions, non-bridal occasions including self-purchase and gifting now represent three-quarters of overall US demand.
This diversification of purchase occasions is significant for retailers. It means that fancy shape diamonds are no longer confined to engagement ring showcases, they are becoming everyday luxury items.
Belgium:
Antwerp, historically the world's diamond capital, is showing strong recovery momentum. The Antwerp World Diamond Centre reported that combined diamond imports and exports rose 9% in value to $10.6 billion and 14% in volume to 38.9 million carats in the first half of 2026.
Small goods (0.20 carats and below) are performing well, while larger ovals and marquises are also in demand. Rough diamond imports increased 14% by volume, with significant gains from Botswana (162%), Angola (56%), and the UAE (53%).
For B2B buyers,sourcing diamonds through Antwerp-connected suppliers on CaratXprovides access to this resurgent trading hub.
Israel:
The Israeli diamond industry is experiencing its most severe downturn in modern history. Polished diamond exports fell 22% year over year to $625.7 million in H1 2026, with total exports reaching just $2.4 billion, the lowest figure in the industry's history.
The challenges are multifaceted: Dubai's tax advantages have attracted Israeli dealers, lab-grown diamonds have eroded natural diamond demand, and a new 10% US tariff has made Israeli exports less competitive. About 60% of Israel's diamonds are sold in the United States, making the tariff particularly damaging.
Some Israeli dealers are adapting by buying diamonds in India and selling them in the US, effectively bypassing the traditional Israeli trading infrastructure.
India:
India's diamond market is showing encouraging signs of recovery driven by retailer restocking and strong domestic demand. The 0.30-carat category is especially strong because supply is tight, while rounds in 0.50-carat and 2-carat-plus ranges are in strong demand.
Diamond demand is strengthening, driven by luxury buyers and rising consumption in tier II and tier III cities. Stars andmelee diamondsare also seeing increased demand, with local brands actively purchasing.
For B2B sellers looking totap into India's growing diamond market, CaratX provides direct access to verified buyers across the subcontinent.
Hong Kong:
Hong Kong's diamond market is characterized by selective, high-value buying. High-end buyers are actively trading 2-carat-plus fancy shape diamonds, while lower-quality diamonds under 1 carat are struggling.
The Hong Kong International Jewellery Show 2026 reflected a more disciplined market, with Southeast Asian and Indian buyers dominating attendance. Larger stones particularly diamonds above 5 carats in D-G color and IF-VVS clarity drew strong attention as investment-grade assets.
High-quality pink and fancy-intense yellow diamonds continue to attract interest from collectors and investors.
The Premiumization Trend:
Across all markets and shapes, one consistent theme emerges: premiumization. Buyers are increasingly willing to pay premiums for exceptional quality, whether measured in cut precision, color saturation, clarity, or carat weight.
This has profound implications for inventory management. The "bread and butter" goods that once formed the backbone of diamond retail sub-carat, commercial-quality stones are facing unprecedented competition from lab-grown diamonds. Meanwhile, the premium segment continues to thrive.
For B2B sellers, this meanslisting high-quality fancy shape diamonds on CaratXto reach buyers specifically seeking premium inventory. For B2C buyers, it means working with suppliers who can provide certified, well-cut stones with verified provenance.
Frequently Asked Questions -
Q: Which fancy shape diamond is the best investment in 2026?
A: Marquise diamonds currently command the highest premiums due to extreme supply scarcity, particularly in 2-carat-plus sizes with D-F color and excellent symmetry. However, all well-cut fancy shapes in larger sizes are outperforming the broader market.

Q: Are lab-grown diamonds affecting fancy shape demand?
A: Lab-grown diamonds are primarily impacting the sub-carat and commercial-quality segments. The premium fancy shape market 2-carat-plus, well-cut, natural diamonds remains relatively insulated because lab-grown producers have not yet achieved widespread production of high-quality large fancy shapes at competitive price points.
Q: What should I look for when buying a fancy shape diamond?
A: Unlike round brilliants, fancy shapes do not receive a cut grade from GIA. Key factors include length-to-width ratio, symmetry, polish, and the overall visual appeal of the shape. For ovals and marquises, avoid "bow-tie" effects (dark areas across the center). Always insist on a GIA or AGS certificate.
