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. 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.

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.

Other drivers and restraints analyzed in the detailed report include:

• Rising Influence of Social Media and Celebrity Culture
• Growing Demand for Sustainable and Ethically Sourced Diamonds
• Competition from Alternative Gemstones

Segment Analysis

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.

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. 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.
