Product Type Insights
Polished diamonds dominate the global diamond market, accounting for approximately 68% of total revenue in 2024. This dominance is primarily driven by sustained demand from the bridal and luxury jewelry segments, where polished stones are essential for finished jewelry products. Among polished diamonds, round brilliant and princess cuts remain the most popular shapes globally, benefiting from their superior light performance, standardized grading, and strong consumer recognition. These cuts are particularly favored in engagement rings, which represent the highest-value jewelry category.
Rough diamonds form the upstream foundation of the value chain and are largely traded between mining companies, large diamantaires, and cutting and polishing centers before being converted into polished stones. While rough diamonds contribute a lower direct revenue share, their pricing dynamics significantly influence downstream margins. Meanwhile, lab-grown polished diamonds are gaining market share at a rapid pace due to their affordability, consistent quality, and ethical sourcing credentials. This segment is increasingly driving volume growth, particularly in fashion jewelry and entry-level bridal categories, making polished diamonds, both natural and lab-grown, the clear product type leader globally.
Application Insights
Jewelry applications account for approximately 85% of the global diamond market in 2024, making it the largest and most influential application segment. Demand is led by rings, necklaces, earrings, and bracelets, with engagement and wedding jewelry serving as the primary revenue drivers due to higher per-unit pricing and emotional purchasing behavior. Cultural traditions, rising disposable incomes, and increasing brand-driven premiumization continue to reinforce jewelry’s dominance across developed and emerging markets.
Industrial and technical applications, while smaller in value contribution, represent the fastest-growing application segment, supported by rising adoption in electronics, automotive manufacturing, construction, cutting tools, and precision optics. Diamonds’ exceptional hardness and thermal conductivity make them indispensable in advanced manufacturing. Emerging high-tech applications, such as thermal management in semiconductors, quantum computing substrates, laser optics, and precision medical instruments, are accelerating industrial diamond demand. This diversification is improving market resilience by reducing reliance on discretionary luxury spending.
Distribution Channel Insights
Specialty jewelry retailers hold the largest distribution share at approximately 42% in 2024, benefiting from strong consumer trust, in-store expertise, customization capabilities, and premium brand positioning. These retailers play a critical role in high-value purchases such as bridal jewelry, where consumers seek assurance on quality, certification, and after-sales services.
Direct-to-consumer (D2C) and online channels are the fastest-growing distribution segment, driven by the rising acceptance of lab-grown diamonds, transparent pricing models, and digital-first marketing strategies. Online platforms enable wider product comparison, certification access, and customization tools, appealing strongly to younger buyers. Wholesalers and diamond bourses remain essential for rough and polished diamond trading, particularly in major hubs such as Antwerp, Dubai, Mumbai, and Hong Kong. Meanwhile, long-term OEM supply contracts dominate industrial diamond distribution, ensuring stable demand from electronics and manufacturing companies.
Traveler Type Insights
From a consumer segmentation perspective, high-net-worth individuals (HNWIs) dominate demand for natural diamonds and luxury jewelry, driven by their preference for exclusivity, rarity, and long-term value retention. This segment supports premium pricing and sustains demand for high-carat, high-quality polished diamonds.
In contrast, millennials and Gen Z consumers are the primary growth drivers for lab-grown diamonds, favoring affordability, sustainability, and ethical sourcing. Their purchasing behavior is strongly influenced by digital platforms, social media, and transparency. Industrial buyers, including electronics manufacturers, automotive OEMs, and medical device companies, form a stable, long-term demand base, often operating under multi-year procurement contracts that provide predictable revenue streams for synthetic diamond producers.
