What Driesassur does
Driesassur is a Belgian insurance brokerage firm founded in 1949 and headquartered in Antwerp, specializing exclusively in coverage for the diamond, jewelry, watch, and fine art sectors. The firm operates as a Lloyd's Coverholder through SIACI Underwriting, placing complex specialty risks with Lloyd's of London capacity. Its product portfolio comprises five core lines: Jewellers Block Insurance (for jewelers, watch traders, precious stone dealers, manufacturers, wholesalers, and private collectors), Processing Insurance (covering the stone lifecycle from rough to polished including re-polishing), Credit Insurance (covering receivables against customer insolvency and payment delays), Terrorism Insurance, and Fine Art & Collectibles Insurance (covering fine art, jewelry, bullion, wine, stamps, manuscripts, valuable papers, guns, coins, classic cars, galleries, and auction houses).
The firm operates a relationship-driven, specialized distribution model with 11 offices across Europe, North America, Asia, Middle East, and Africa — including a six-office Indian partnership network via Unilight Reinsurance Brokers (Mumbai, Surat, Kolkata, Bhubaneswar, Jaipur, Goa) and Hong Kong operations through Nova Insurance Consultants. Revenue is generated through brokerage commissions on policies placed with insurers and reinsurers, with quote-based pricing tailored to each client's risk profile. The firm is positioned as the preferred broker for 80% of De Beers customers and claims 2,873+ clients served globally.
Driesassur is a subsidiary of France-based Diot-Siaci Group, a multi-specialist insurance and reinsurance brokerage that generated nearly €800 million in 2022 with ~5,000 employees. The firm has consolidated its focus by divesting a substantial portion of its traditional Antwerp insurance portfolio (covering private clients, SMBs, and large companies outside its specialty) to Vanbreda Risk & Benefits, retaining concentration on diamond, jewelry, and fine art verticals. Go-to-market relies heavily on direct enterprise field sales supported by event-driven presence at major industry trade shows including JCK Las Vegas, GemGenève, VicenzaOro, Art Basel, and TEFAF.

Driesassur competitors and assessment
Company assessmentBroad incumbents
- Marsh: Marsh is a global insurance broker with a specialty private client and fine art practice serving the same high-net-worth and corporate collector segments. Comparable to Driesassur in product overlap, though Marsh is a broad incumbent with much wider portfolio than the diamond/jewelry specialist.
- Aon: Aon is a global insurance brokerage leader with dedicated fine art and jewelry specialty practices serving HNW and trade clients. Comparable to Driesassur in product offering and customer segments, but much broader in scale and geographic reach as a global incumbent.
- Arthur J. Gallagher & Co. Gallagher is a global insurance brokerage and risk management firm with specialty practices covering fine art, jewelry, and luxury asset risks. Comparable to Driesassur as both arrange insurance for high-value collectible assets, though Gallagher operates at broader scale across many lines.
- Willis Towers Watson: WTW is a global advisory and brokerage firm with specialty fine art and jewelry practices serving collectors, galleries, and corporate clients. Comparable to Driesassur in serving the same niche customer segments, but operates as a broad incumbent across many insurance lines rather than specializing solely in diamond/jewelry trade.
Direct peers
- Hiscox: Hiscox is a specialty insurer operating through Lloyd's and US/EU markets, with dedicated fine art and jewelry products for private collectors and trade. Directly comparable to Driesassur because both serve the same HNW and trade-art insurance market through specialty underwriting expertise.
- AIG Private Client Group: AIG's Private Client Group provides tailored insurance for HNW individuals including jewelry, fine art, and collectibles worldwide. Comparable to Driesassur in targeting the same HNW private client segment with specialty products, though AIG operates as a carrier across a much broader portfolio.
- Beazley: Beazley is a Lloyd's-based specialty insurer with art, jewelry, and specie coverage lines targeting trade and private clients. Comparable to Driesassur because both operate within the Lloyd's ecosystem to underwrite or place specialized high-value-asset risks across multiple jurisdictions.
- Vanbreda Risk & Benefits: Vanbreda is Belgium's largest insurance broker and acquired a substantial part of Driesassur's Antwerp insurance portfolio. Directly comparable as a Belgian-headquartered broker with overlap in corporate and private client segments, and a structural counterparty given the disclosed portfolio transaction.
- Chubb: Chubb's Masterpiece product line offers fine art, jewelry, and collectibles coverage for high-net-worth clients globally. Comparable to Driesassur as both target the HNW segment and specialty trade risks, though Chubb operates as a carrier at much greater scale.
