India Diamond Market Outlook 2026–2034: Size, Share, Trends, Demand and Report

India Diamond Market Outlook

The India diamond market is progressing through a period of structural rebalancing, as global demand weakness in natural diamonds is offset by supportive government policy, aggressive organized retail expansion, and the rapid rise of lab-grown diamonds as a distinct growth segment.

Government initiatives such as the Diamond Imprest Authorization Scheme and safe harbour tax rates for foreign mining companies are strengthening India's position as the world's dominant diamond processing hub, even as exporters navigate declining Western demand and looming US tariff uncertainty. At the same time, rising disposable incomes, changing consumer preferences among millennials and working women, and deep retail penetration into tier-2 and tier-3 cities are sustaining domestic consumption.

As lab-grown diamonds mature from a niche alternative into a mainstream, policy-backed manufacturing segment, and as organized jewelry chains extend branded, certified offerings deeper into India, the market is shifting from an export-dependent processing model toward a more balanced structure built on domestic demand, manufacturing diversification, and technology-led efficiency.

Executive Summary

India's diamond market is set to grow from USD 3.49 Billion in 2025 to USD 5.29 Billion by 2034, at a CAGR of 4.72% during 2026–2034 — a more measured growth trajectory than other consumer categories, reflecting the sector's ongoing exposure to global export demand cycles even as domestic consumption strengthens. Government policy is playing an outsized role in shaping market resilience: the Diamond Imprest Authorization Scheme, effective April 2025, permits duty-free imports of small natural cut and polished diamonds for qualified exporters, directly protecting India's processing base and MSME employment.

Meanwhile, organized retail chains — led by multi-brand players such as Titan's Tanishq, Zoya, CaratLane, and Mia, alongside Malabar Gold & Diamonds, Kalyan Jewellers, and Senco Gold — are expanding aggressively into tier-2 and tier-3 cities, capturing demand from a growing base of aspirational, self-purchasing consumers.

Lab-grown diamonds are emerging as a parallel growth engine, concentrated in Gujarat and Maharashtra and increasingly backed by favorable customs and import-code policies, even as the natural diamond export segment contends with its steepest decline in two decades.

India Diamond Market Key Drivers

• Government Policy Support and Trade Facilitation Measures

The Diamond Imprest Authorization Scheme directly addresses beneficiation policies in producing countries that threaten India's raw material access, safeguarding domestic processing capacity and preserving employment across major polishing hubs. Complementary reforms — safe harbour tax rates for foreign mining companies, reduced customs duties on precious metals, and Authorized Economic Operator status — are simplifying taxation, minimizing disputes, and streamlining export-import operations through faster clearances, collectively supporting employment for over a million workers across the diamond value chain.

• Aggressive Retail Expansion and Premiumization Strategy

Organized jewelry chains are rapidly extending branded, certified offerings into tier-2 and tier-3 cities, mirroring the retail evolution seen earlier in China. Corporations such as Titan Company have adopted multi-brand strategies spanning traditional and aspirational consumer segments, while retailers are allocating more shelf space to studded jewelry and integrating digital channels for personalized shopping — a shift accelerated by changing consumer behavior, particularly among working women embracing jewelry as self-expression.

• Emergence and Growth of Lab-Grown Diamonds

India is leveraging its established cutting and polishing expertise to become a global leader in lab-grown diamond production. The elimination of the 5% customs duty on diamond seeds and the creation of distinct import codes for LGDs have reduced input costs and improved regulatory clarity, drawing substantial private investment into Gujarat- and Maharashtra-based CVD manufacturing and fueling export growth to the US, UAE, and Hong Kong.

India Diamond Market Emerging Trends

• AI-Driven Precision Manufacturing

Artificial intelligence is transforming diamond processing by analyzing the unique characteristics of each rough stone to determine optimal cutting strategies, maximizing yield while reducing material waste. AI-driven automated cutting, sorting, and grading systems are improving consistency and accelerating processing timelines — efficiency gains that translate directly into cost advantages in India's competitive manufacturing sector.

• Rising Consumer Preference for Ethical and Sustainable Sourcing

Growing awareness among millennials and Gen Z consumers about ethical sourcing and environmental responsibility is boosting lab-grown diamond jewelry demand, prompting major retailers to introduce lab-grown options alongside natural stones as a distinct, values-driven product category.

• Deepening Brand Partnerships and Consumer Education

Established players are investing in category-wide consumer education and authenticity assurance to defend natural diamond demand. Tanishq's three-year strategic collaboration with De Beers Group, focused on consumer education, retail staff training, and marketing campaigns, reflects industry efforts to reinforce India's position as the world's second-largest natural diamond jewelry market, representing roughly 11% of global demand.

India Diamond Market Challenges

Despite policy support and domestic demand strength, the market faces significant structural headwinds:

• Export decline and weak global demand — India's diamond export industry is experiencing its steepest decline in two decades, driven by weakened consumer spending in the US and China and a growing shift toward lab-grown alternatives, forcing processing units in Surat and Mumbai to reduce operations or shut down
• US tariff uncertainties and trade policy volatility — a proposed 50% US tariff on Indian diamond imports, though temporarily delayed, has triggered shipment delays, cautious ordering, and tightening credit conditions, with exporters exploring risk-laden rerouting through intermediary markets
• Price volatility and inventory management challenges — falling global diamond prices, an oversupply of rough stones, and competition from cheaper lab-grown alternatives are squeezing manufacturer margins and tying up working capital in unsold inventory, compounded by tightening bank credit
