The diamond jewelry market, valued at USD 389.5 billion in 2025, is projected to reach USD 605.7 billion by 2035, growing at a CAGR of 4.8%. The market is witnessing a shift in consumer preferences, sustainability trends, and evolving retail strategies.
In 2024, the diamond jewelry industry faced both challenges and opportunities. Inflationary pressures impacted discretionary spending, leading to a temporary slowdown in luxury purchases in key markets like the USA and Europe. However, demand remained resilient in China and India, driven by weddings and cultural events.
The rise of lab-grown diamonds (LGDs) continued, capturing a larger market share as sustainability-conscious consumers sought ethical alternatives. Major brands such as De Beers and Signet Jewelers responded with diversified offerings, balancing mined and synthetic diamonds.
Retailers embraced omnichannel strategies, with leading companies enhancing digital experiences through AI-driven personalization, virtual try-ons, and direct-to-consumer (DTC) models. Meanwhile, geopolitical uncertainties, particularly in Russian diamond supply chains, prompted diversification efforts among global players.
Looking ahead, branding, innovation, and sustainability will shape the future. Companies investing in transparency, ethical sourcing, and digital transformation will gain an edge. While traditional luxury buyers remain key, younger generations, influenced by affordability and ethics, will redefine the industry’s growth trajectory.

Specialty stores and luxury boutiques continue to attract customers seeking exclusive, custom-made pieces, while departmental stores have seen a decline due to the shift toward direct-to-consumer and online platforms.
Other sales channels such as duty-free shops, private sales, and auction houses cater to a niche audience, with investment-grade diamonds and rare jewelry pieces gaining prominence in the secondary market.

A growing trend among working professionals is self-purchasing, with a preference for everyday wear that balances luxury with practicality.
Men’s diamond jewelry has seen a surge in popularity, with bracelets, rings, and earrings becoming more common in high-end fashion. Influencer and celebrity endorsements have played a key role in this transformation, making diamond jewelry a unisex fashion statement. The emergence of gender-neutral collections is reshaping the market, with leading brands introducing minimalist, geometric, and versatile designs that appeal to modern consumers.
The global diamond jewelry market is experiencing dynamic shifts, influenced by evolving consumer preferences, technological advancements, and economic factors. The rise of lab-grown diamonds has introduced a significant alternative to natural diamonds, appealing to consumers seeking ethical and affordable options.
