Gems and Jewellery Insurance in India: Covering Surat, Mumbai, and SEEPZ

India is the world's largest processor of diamonds (accounting for roughly 55% of global rough-diamond cutting and polishing) and a top exporter of coloured gemstones, pearls, and finished jewellery. The sector generated approximately USD 40 billion in exports in FY2025 and employs over 2.3 million workers across clusters in Surat, Mumbai, Jaipur, Bangalore, and Pune.

The gems and jewellery industry carries insurance exposure fundamentally different from general retail. Inventories move constantly: from vault storage to in-hand workshop processing, to consignment placement in retail outlets, to international air/courier shipment. Individual pieces carry high unit value (a single gemstone or finished ornament can exceed INR 100 lakhs), making even small losses material. Burglary, armed robbery, and dishonesty represent the primary loss drivers, followed by transit breakage and loose-stone exchange fraud.

The Jewellers Block Policy (JBP) is the standard risk-transfer product for the gems and jewellery trade. Unlike standard burglary or transit policies, JBP integrates multiple peril covers into a unified policy designed for the unique loss patterns of jewellers, diamond dealers, and gemstone traders.

Typical JBP coverage includes: (1) all-risks stock-in-vault (usually subject to a specified deductible of INR 5 lakhs or more, and a sum-insured declared annually); (2) all-risks stock-in-transit, whether by courier, armoured vehicle, or hand-carry via angadia (traditional diamond courier) networks; (3) stock-on-consignment placed in retail outlets or exhibition halls; (4) loose gemstone exchange and valuation loss; (5) equipment and tools in-situ at the workshop; (6) jewellery receivable on assignment. Coverage for in-transit is typically the highest risk segment because jewellers move inventory constantly between locations, often via informal angadia networks where security is based on reputation and community accountability rather than formal insurance.

Burglary and armed robbery form the largest loss frequency and severity component for jewellers block underwriters. Surat's diamond-cutting cluster (primarily in areas like Mahidhpur and Kathlal) has experienced notable burglary activity despite industry vigilance. In Mumbai, the concentration of jewellery shops and wholesalers in Zaveri Bazaar, Bhuleshwar, and Fort creates high-value density that attracts organized theft rings. SEEPZ (Special Economic Zone) in Mumbai and the Bharat Diamond Bourse in Ramlal Ghat have enhanced security infrastructure but remain targets because of the value concentration.

Underwriters assess burglary risk using facility-specific metrics: (i) vault construction (RCC walls, reinforced door with time-lock, anchor-bolting specifications); (ii) alarm system grade (SSIC/UL-approved Grade A or B systems with 24/7 central monitoring); (iii) trained security personnel (full-time guarding, shift rotations, background checks); (iv) proximity to police stations; (v) crime history of the area; and (vi) jeweller's own loss history. Premiums for high-security facilities in established business addresses (like registered offices in BKC Mumbai or SEEPZ) may range from 0.5%-1.5% of sum-insured, while standalone, less-secure premises can incur loadings of 3%-5% or higher.

Movement of gemstones and jewellery in-transit is where many losses occur. Historically, gemstone traders in Surat and Mumbai relied on angadia networks (community-based courier systems with centuries of trust embedded in reputation). Angadias operate through personal relationships and community accountability rather than insurance and formal legal contracts. A jeweller consigns a packet of diamonds worth INR 1 crore to an angadia, who physically carries it via train or car to another jeweller in Bangalore or Jaipur, returning with payment or fresh inventory.

For insurance purposes, angadia transit carries higher premiums because the risk of loss in a remote location (between towns, overnight stops, or during informal transfers) is harder to verify. Courier alternatives (FedEx, Blue Dart, specialist jewellery couriers like SAVE or Guardian) offer formally insurable transit options but at higher cost. Underwriters require: (i) documented proof of courier service engagement; (ii) GPS tracking where available; (iii) declared value on courier labels; (iv) photography and weight certification at pickup and delivery; (v) courier company's own liability coverage. JBP in-transit premiums typically range from 0.75%-2% of declared value depending on routing, frequency, and security method.

Post-2020, India's financial-crime compliance requirements tightened significantly. Insurance companies underwriting jewellers block policies face escalated Know-Your-Customer (KYC) and Prevention of Money Laundering Act (PMLA) obligations. Jewellers have been flagged by financial-intelligence units as higher-risk customers because gemstones (especially loose diamonds and pearls) are portable, fungible, and difficult to trace. This creates regulatory pressure on underwriters to validate that policyholders are legitimate businesses with genuine operational need for insurance.

Before issuing or renewing JBP, insurers verify: (i) business registration (GST, PAN, shop-licensing); (ii) bank statements showing regular trade activity; (iii) source of funds (prior loss claims should not be the sole funding source); (iv) beneficial ownership disclosure; (v) customer sanction list checks; (vi) transaction patterns (legitimate jewellers show consistent buy-sell cycles, not erratic valuations). High-risk scenarios include undisclosed beneficiaries, cash-heavy transactions, vague or unregistered business structures, or losses followed by immediate policy cancellation and renewed applications elsewhere. These red flags can trigger policy cancellation or non-renewal.

Jewellers often place stock on consignment in retail outlets or exhibit pieces in trade fairs and exhibitions. This creates a distinct coverage challenge. Unlike vault or workshop stock where the jeweller controls the environment, consignment stock sits in a retail shop operated by someone else, or in a temporary exhibition space where security is shared.

JBP consignment coverage requires the jeweller (consignor) and retailer (consignee) to maintain documented inventory records. Each piece should be documented with photograph, weight, gemstone description, and agreed valuation. When a piece is sold, the consignee remits payment to the consignor. When a piece is damaged or lost, the jeweller must prove its existence at the consignee's location through contemporaneous records.

Exhibition coverage (for trade fairs, wedding expos, art galleries) presents similar issues but with added complexity because security is temporary and multiple jewellers' inventories may be co-located. Underwriters typically require: (i) exhibition insurer's own All-Risks policy covering venue; (ii) security arrangement details (guards, CCTV, alarm systems); (iii) daily reconciliation of inventory; (iv) casualty reporting within 48 hours. Deductibles for consignment and exhibition can be higher (INR 10 lakhs or more per event) because of difficulty in loss verification.

Loose gemstone trading (particularly in diamonds, rubies, sapphires, and pearls) introduces a specific fraud pattern that underwriters must guard against. A jeweller purchases loose stones from a supplier, pays by cheque or bank transfer, and then claims the stones were damaged, misplaced, or switched (swapped with lower-grade stones). Because gemstone grading involves subjective assessment (colour, clarity, cut, carat), and because loose stones are fungible and difficult to authenticate post-loss, this creates fertile ground for collusion between jeweller and supplier, or fabricated losses.

To mitigate this, JBP policies often exclude or heavily restrict loose-stone coverage, or place it under a separate sub-limit with high deductibles. When loose-stone coverage is offered, underwriters require: (i) gemologist-certified valuations at purchase (with independent laboratory certificates from bodies like GIA, IGI, or IMARC); (ii) photographic and video documentation of stones before and after any treatment; (iii) detailed transaction records with suppliers; (iv) third-party inspection of claimed damage (gemologist or independent surveyor, not the jeweller's nominee). Premiums for loose-stone exchange coverage can range from 2%-5% of sub-limit, reflecting the elevated fraud risk.

Underwriting strategy for gems and jewellery insurance varies significantly by location and cluster. Surat's diamond-cutting sector (home to approximately 500,000 artisans and 15,000 registered diamond-processing units) operates in a mature, well-organized ecosystem. Insurance penetration is high, underwriters have deep historical loss data, and the cluster has invested in shared security infrastructure (cluster police stations, industry security councils). Surat premiums are typically moderate because loss frequency is proportional to volume, and organized crime is lower relative to unregulated areas.

Mumbai's Zaveri Bazaar and Fort jewellery cluster combines traditional retail with wholesale operations and is characterized by older buildings, narrow lanes, and higher population density. Security infrastructure is fragmented, and organized theft rings have historically targeted this cluster. Premiums in these areas are typically 50%-100% higher than Surat.

SEEPZ Mumbai and the Bharat Diamond Bourse (BDB) operate under special-zone governance with enhanced customs and security oversight, making them lower-risk underwriting. The BDB, inaugurated in 2010, houses over 4,000 member dealers in a purpose-built facility with world-class security. Premiums for SEEPZ and BDB entities are typically 20%-30% lower than traditional bazaars because security infrastructure is standardized and regulatory oversight is stronger.
