Diamond Jewelry Market Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

Global Diamond Jewelry Market Trends and Insights

Growing Demand for Bridal and Wedding Jewelry

Bridal purchases continue to support the Diamond jewelry market because a ring is part of most proposal occasions. The Knot reported that nearly 9 in 10 proposers gave a ring during the proposal, while lab-grown center stones represented 61% of U.S. engagement-ring purchases by unit count in 2026. The same study reported average engagement-ring spending of USD 4,600 and an average center stone size of 1.9 carats. 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. In India, bridal and wedding occasions accounted for 86% of natural diamond consumption, while self-gifting and anniversary purchases broadened repeat demand. The Kimberley Process covers more than 99% of global rough diamond trade, making its certification a core trust requirement for retailers serving bridal buyers 

Increasing Jewelry Customization

Customization is becoming a standard part of the Diamond jewelry market, especially in mid-priced and premium engagement jewelry. The supplied research indicates that 88% of U.S. couples selected customized engagement rings in 2025, shifting demand from standard catalog products toward tailored designs. Natural Diamond Council research identified nostalgia, self-expression, and vintage styles as major consumer themes, supporting demand for Art Deco cuts, stacked rings, and heirloom-style settings^{[1]Source: Natural Diamond Council and Tenoris, “Natural Diamond Trends: A 2025 Overview,” Natural Diamond Council, naturaldiamondcouncil.org}. Lower per-carat lab-grown diamond prices give buyers more budget for metalwork, engraving, and fancy cuts. This makes customized jewelry more accessible across the USD 2,000 to USD 6,000 price range. Brands that combine design consultation with clear diamond information can improve conversion without relying only on promotional pricing.

Rising Influence of Social Media and Celebrity Culture

Social media shortens the time between a visible design moment and retail demand in the Diamond jewelry market. Natural Diamond Council and Tenoris data linked Selena Gomez’s engagement announcement, which featured a marquise ring, to higher sales of marquise-cut diamonds among U.S. specialty jewelers. De Beers reported that Gen Z represented 18% of U.S. natural diamond purchasers and 23% of demand by value in 2026. The group also reported 1.83 annual purchase occasions for Gen Z buyers, compared with an industry average of 1.7 occasions. Bridal purchases accounted for 45% of Gen Z natural diamond demand in this research. Faster trend cycles are encouraging brands to use smaller capsule collections and limited editions that reflect changing tastes without extending inventory risk.

Growing Demand for Sustainable and Ethically Sourced Diamonds

Ethical sourcing has become a commercial requirement in the Diamond jewelry market, rather than a limited brand claim. The Kimberley Process chair in 2026 called for stronger traceability standards, digital communication, and improved management of financial integrity risks. De Beers introduced its ORIGIN branded polished diamond program in North America in 2025 through 19 retail partners, using the Tracr platform to provide mine-to-market provenance. The program gives participating retailers a verifiable product history that can support customer discussions on origin. The Luanda Accord linked diamond-producing countries with category marketing investment in 2025, placing provenance messaging alongside demand-generation activity. Lab-grown diamonds can avoid mining-related land use, although their CVD and HPHT production methods still require substantial energy. Clear evidence on source and production method can therefore matter more than broad sustainability claims.

High Cost of Natural Diamond Jewelry

The cost of natural diamond jewelry remains a constraint because buyers can compare it directly with lower-priced lab-grown stones. The supplied research reported that an unbranded 1-carat round lab-grown diamond cost USD 845 in Q1 2025, compared with USD 3,895 for a comparable natural stone. De Beers identified the 0.3 to 1-carat natural diamond range as the area most affected by synthetic diamond demand. Record gold prices in 2025 increased the total cost of jewelry with gold settings, particularly for buyers with fixed budgets. The challenge is greater in developing retail markets, where resale options for natural diamond jewelry are less formalized. Premium products retain more pricing power, while the mid-priced natural diamond segment faces continuing pressure on purchase volume.

Competition from Alternative Gemstones

Alternative gemstones are competing for purchase occasions that traditionally favored diamonds in the Diamond jewelry market. Colored sapphires, emeralds, rubies, and moissanite provide more choices for buyers who prioritize design distinction over the traditional diamond status signal. Pandora expanded its material range in 2026 with platinum-plated designs while continuing its development of lab-grown diamond jewelry. Research from The Plumb Club found that 37% of U.S. consumers lacked enough information to distinguish natural and lab-grown diamonds. YouGov found that 29% of U.K. adults would consider a lab-grown diamond, rising to 49% among adults aged 18 to 24^{[2]Source: YouGov, "Who's Buying Lab-Grown Diamonds in the UK?", yougov.com}. Diamond certification remains an important differentiator in bridal jewelry, where buyers often place a high value on independently documented quality.

Segment Analysis

By Product Type: Necklaces and Non-Bridal Formats Gain Structural Momentum

Rings held 48.67% of 2025 product value and remained the largest product category in the Diamond jewelry market. Their position reflects the continuing importance of engagement rings across major consumer regions. Necklaces are forecast to grow at a 6.24% CAGR through 2031 as lower lab-grown diamond prices extend access to tennis necklaces, layered pendants, and statement chains. The supplied research showed that tennis bracelets rose from 3.5% of lab-grown diamond product sales in 2020 to 11.9% in 2025. This shift indicates that buyers are using diamonds in more everyday formats, rather than only for an engagement purchase.

Earrings remain an accessible entry format for first-time buyers, particularly in Asia-Pacific. Pendants and chains are increasingly promoted as unisex jewelry, including within the expanding male fine-jewelry category. De Beers introduced its Desert Diamonds Icons campaign in 2026 around the eternity band, tennis bracelet, and halo pendant. These 3 formats accounted for 70% of diamond jewelry acquisitions in the supplied research. De Beers also reported that gifting represented 44% of natural diamond jewelry sales in 2025 and self-purchases represented 31%. The expansion of these occasions supports more balanced product demand across the Diamond jewelry industry.

By Diamond Type: Natural Diamonds Rebuild Premium Value as Supply Contracts

Lab-grown diamonds held 65.43% of the 2025 diamond-type value in the Diamond jewelry market. Their position rests on lower prices and their broad acceptance in engagement-ring center stones. Natural diamonds are forecast to grow at a faster 6.35% CAGR through 2031, supported by lower supply and premium positioning. De Beers reported that natural diamonds represented 85% of independent jewelers’ diamond sales by value in 2025, compared with 15% for lab-grown diamonds. Value patterns therefore differ from purchase-unit patterns across this category.

Natural diamond production is expected to remain constrained as mines close, and producers reduce output. Antwerp World Diamond Centre reported 105 million carats of global production in 2025, down 13% from 2022^{[3]Source: Antwerp World Diamond Centre, “Antwerp Diamond Industry Trade Figures 2025,” Antwerp World Diamond Centre, awdc.be}. De Beers’ 2026 production guidance of 21 to 26 million carats reflects the same tighter supply environment. The supplied research also indicated slower sales of lab-grown stones weighing 3 carats or more. That result suggests that larger stones do not always create proportional demand once size is no longer the primary constraint. Natural diamonds can benefit when brands connect rarity and provenance with self-expression rather than relying only on bridal tradition.

By Color Type: Warm-Toned Diamonds Expand the Addressable Base

Colorless diamonds held 78.43% of the 2025 color-type value, making them the leading part of the Diamond jewelry market. Their position is supported by the established D to Z grading system and its role in bridal buying decisions. Colored diamonds are projected to grow at a 5.82% CAGR through 2031. De Beers reported 15% year-over-year sales growth for colored and low-colored natural diamonds at U.S. specialty retailers in Q4 2025. The same products recorded 19% year-over-year growth in Q1 2026 after the Desert Diamonds campaign.

Warm white, champagne, and K to Z natural diamonds offer a route to broaden the available range without competing only on the highest color grades. De Beers positioned these diamonds through a campaign centered on individuality and rarity. The supplied research noted a split in China between collectible colored stones and top-grade colorless diamonds, which retained premiums, and commercial-grade colorless diamonds, which faced lab-grown competition. Certified natural fancy colors remain important for high-value jewelry because rarity is easier to explain with independent grading. At the same time, colorless stones continue to play a central supporting role in multi-stone high-jewelry designs. A wider color offering can help retailers serve buyers seeking design variation without leaving the diamond category.

By Metal Type: Platinum’s Value Proposition Strengthens Against High Gold Prices

Gold held 42.83% of 2025 metal-type value in the Diamond jewelry market. Its leading position reflects cultural importance in Asian bridal jewelry and its association with stored value in South Asian and Middle Eastern markets. Platinum is forecast to grow at a 5.79% CAGR through 2031. The World Platinum Investment Council reported that global platinum jewelry demand grew 7% in 2025 to 2,157 thousand ounces, its highest level since 2018. The growing price gap between platinum and gold improved platinum’s appeal for retailers and buyers.

China’s platinum jewelry fabrication increased 56% to 589,000 ounces in 2025, according to the supplied research, as retailers shifted inventory from gold toward platinum. In Japan, platinum represented 28% of unit sales, reflecting the country’s long-established preference for the metal. North American platinum jewelry demand grew 6% in 2025, while more than 75% of surveyed fine-jewelry retailers planned to expand platinum inventory in 2026. Silver and other metals remain relevant at entry price points, but higher input costs are increasing material substitution. Pandora launched platinum-plated versions of key bracelets after silver costs more than doubled in 2025. This response shows how metal selection is becoming an active commercial decision across price tiers.

By Distribution Channel: Omnichannel Integration Separates Leaders from Laggards

Offline stores accounted for 69.72% of 2025 distribution value in the Diamond jewelry market. In-person service remains important for natural diamond purchases that require visual comparison, authentication, and detailed advice. Online stores are forecast to grow at a 6.21% CAGR through 2031. Remote sales work well for lab-grown diamonds because standardized grading certificates and transparent prices can reduce buyer uncertainty. Online growth is therefore likely to be strongest where purchase criteria can be explained clearly without a store visit.

Signet acquired The Clear Cut to support Blue Nile’s premium natural diamond positioning, combining digital education with broader inventory access. Brilliant Earth reported 43 U.S. showrooms and USD 437 million in FY2025 net sales, showing that an online-first model can scale with a focused physical presence. The company recorded 210,158 orders in FY2025, up 13% from the previous year. The supplied research reported an 81.4% jewelry e-commerce cart abandonment rate, reflecting continuing trust and product-evaluation challenges. Digital tools can improve discovery and convenience, but physical retail retains a strong role for higher-value purchases. The Diamond jewelry industry requires retailers to link online information, product availability, and store-level service into a consistent customer journey.

Geography Analysis

North America held 38.28% of global value in 2025, making it the largest regional part of the Diamond jewelry market. The United States represented 53% of global natural diamond jewelry demand in the supplied research. U.S. jewelry revenue grew 9% in H1 2026, with natural diamonds gaining through higher average selling prices and lab-grown diamonds gaining through higher unit sales. Signet reported FY2026 sales of USD 6.81 billion, same-store sales growth of 1.3%, and an average unit retail price increase of 7%. De Beers Group was available through 19 retail partners at 30 locations in the United States and Canada in 2025, providing retailers with a traceability-based product proposition.

Europe is forecast to grow at a 5.68% CAGR through 2031, the fastest regional rate in the Diamond jewelry market. Richemont’s Jewelry Maisons recorded 8% sales growth in FY2026 to EUR 16.5 billion, equivalent to USD 19.2 billion, and reported double-digit growth in Europe. European platinum jewelry fabrication grew 6% in 2025, marking its fifth consecutive year of growth. Germany, the United Kingdom, France, Italy, and Spain remain important demand centers. Antwerp’s 2025 diamond trade totaled USD 19.07 billion, with polished diamonds accounting for 65.6% of the total.

Asia-Pacific remains highly varied across the Diamond jewelry market. India captured 12% of global natural diamond demand in 2025, compared with 5% each for China and Japan. Kalyan Jewellers reported FY2026 revenue of INR 35,743 crore, equivalent to USD 4.2 billion, up 43% year over year. China is seeing stronger natural diamond demand among younger, higher-income buyers, while lab-grown products continue to pressure the natural diamond mid-market. South America has demand centered on branded luxury retail and urban e-commerce, while new trade routes may support more competitive supply. The Middle East and Africa benefit from Dubai’s role as a trading hub, and Richemont identified the region as a leading area for wholesale and online growth in FY2026.
