Market Size Overview

The India diamond market size has established itself as one of the more closely watched segments within the country's broader gems and jewelry landscape, reflecting both strong domestic consumption and India's unmatched global role in diamond processing. The India diamond market size reached USD 3.49 billion in 2025 and is projected to reach USD 5.29 billion by 2034, growing at a CAGR of 4.72% during 2026-2034.

This growth is being shaped by a convergence of factors from targeted government policy and organized retail expansion to the rapid emergence of lab-grown diamonds as a distinct and fast-growing segment. The market is driven by supportive government policies, including the Diamond Imprest Authorization Scheme and safe harbour tax rates that strengthen India's position as a global diamond processing leader. Moreover, aggressive retail expansion by major jewelry chains across tier-2 and tier-3 cities, coupled with rising disposable incomes and changing consumer preferences among millennials and working women, is fueling demand.

Factors Driving India Diamond Market Size

• Government Policy and Trade Facilitation

A significant contributor to the expanding India diamond market size is the structured policy support provided by the central government. The newly introduced Diamond Imprest Authorization Scheme, effective April 2025, permits duty-free imports of small natural cut and polished diamonds for qualified exporters, directly addressing beneficiation policies in producing countries that threaten India's raw material access. This initiative safeguards domestic processing capacity, supports MSMEs, and preserves employment across major polishing hubs.

Additionally, safe harbour rates for foreign mining companies have simplified taxation, minimized disputes, and encouraged direct diamond trading with Indian processors, reducing dependence on intermediaries like Dubai. Complementary reforms including reduced customs duties on precious metals and Authorized Economic Operator (AEO) status have streamlined export-import operations through faster clearances and lower guarantee requirements. Together, these policy measures create a more predictable regulatory environment and sustain employment for over a million workers in the sector.

• Retail Expansion and Premiumization

The organized retail push is another key driver of India diamond market size growth. Corporations such as Titan Company have adopted multi-brand approaches Tanishq, Zoya, CaratLane, and Mia catering to distinct market segments ranging from traditional buyers to younger, aspirational consumers. Organized chains like Malabar Gold & Diamonds, Kalyan Jewellers, and Senco Gold are broadening their presence in tier-2 and tier-3 cities, capitalizing on the growing appetite for contemporary designs and diamond-studded collections.

Changing consumer behavior, especially among working women embracing jewelry as self-expression, has accelerated diamond jewelry adoption nationwide. Retailers are allocating more space to studded jewelry, investing in consumer education about diamond quality, and integrating digital channels for personalized shopping experiences.

• Lab-Grown Diamonds Expanding the Market

India is rapidly emerging as a global leader in lab-grown diamond (LGD) production, leveraging its established expertise in cutting and polishing to capture a growing share of this sustainable and affordable market. Supported by favorable government policies such as the elimination of the 5% customs duty on diamond seeds and the creation of distinct import codes for LGDs the sector benefits from reduced input costs and greater regulatory clarity.

Concentrated mainly in Gujarat and Maharashtra, LGD manufacturing employs advanced Chemical Vapor Deposition (CVD) technology to produce high-quality stones with fewer impurities. Domestically, rising awareness among millennials and Gen Z consumers about ethical sourcing and environmental responsibility has boosted LGD jewelry demand, prompting major retailers to introduce lab-grown options alongside natural diamonds.

Market Segmentation

According to IMARC Group, the India diamond market size is analyzed across product, application, and region.

• By Product Natural vs. Synthetic: The market is split between natural and synthetic (lab-grown) diamonds. While natural diamonds continue to hold the larger share of overall India diamond market size due to their deep cultural significance in weddings and festivals, the synthetic segment is growing at a notably faster pace, driven by affordability, ethical sourcing preferences, and government support for domestic LGD manufacturing.
• By Application Jewelry & Ornaments vs. Industrial: Jewelry and ornaments dominate the application segment, accounting for the vast majority of India diamond market size. India represents approximately 11% of global natural diamond jewelry demand, making it the world's second-largest natural diamond jewelry market. Industrial applications, while smaller in overall share, serve precision manufacturing sectors including electronics, cutting tools, and abrasives.
• By Region: The market spans North India, South India, East India, and West India. West India anchored by Gujarat's dominant diamond processing hubs in Surat holds a structurally significant share of India diamond market size, particularly in the manufacturing and export segment. South and North India contribute strongly through retail consumption, with metro cities driving premium and branded jewelry demand.

Key Challenges Affecting Market Size

Despite favorable long-term fundamentals, the India diamond market size faces near-term headwinds that are constraining growth. India's diamond export industry is facing its steepest decline in two decades, reflecting severe global demand contraction. The downturn stems from weakened consumer spending in key markets such as the United States and China, where inflation, economic uncertainty, and a growing preference for lab-grown diamonds have eroded demand for natural stones.

Trade policy uncertainty is adding another layer of pressure. Proposed tariff hikes on Indian diamond imports by the United States have triggered significant unease within India's diamond sector, exposing its heavy reliance on the American market. Although implementation was temporarily delayed, the potential 50% tariff threatens to disrupt supply chains, distort export patterns, and weaken India's competitive position relative to countries facing lower duties.

Additionally, falling global diamond prices, combined with an oversupply of rough stones and competition from cheaper lab-grown alternatives, have squeezed margins for manufacturers who purchased at higher input costs. Many processors are burdened with unsold inventories that tie up working capital and limit new production cycles.

Role of AI in Shaping Market Efficiency

An emerging factor influencing the structural competitiveness of India diamond market size is the adoption of artificial intelligence across the processing value chain. AI-powered systems analyze the unique characteristics of each rough diamond to determine optimal cutting strategies, maximizing yield and value while reducing material waste. Advanced AI-driven automated cutting, sorting, and grading systems enhance consistency, reduce human error, and accelerate processing timelines. As adoption scales, AI integration is expected to improve margins and reinforce India's position as the world's dominant diamond processing hub.

Recent Industry Developments

Several notable developments in 2024 have directly impacted India diamond market size and competitive dynamics. In August 2024, Tanishq announced a three-year strategic collaboration with De Beers Group to promote natural diamonds in India through consumer education, retail staff training, authenticity assurance, and comprehensive marketing campaigns.

In November 2024, the Maharashtra government launched the Gems and Jewellery Policy 2025, targeting investments of Rs. 1 lakh crore and creation of 5 lakh jobs, including provisions for the India Jewellery Park Mumbai project spread over 21 acres in Navi Mumbai, expected to generate over 1 lakh jobs with an estimated investment of Rs. 50,000 crore.

In July 2024, the Union Budget 2024 introduced safe harbour rates for foreign mining companies selling raw diamonds in India, with Finance Minister Nirmala Sitharaman announcing predetermined tax rates to simplify compliance and create a more attractive investment environment for international mining companies.
