What IDEX Online does

IDEX Online is a privately held B2B diamond trading platform founded in 2001 and headquartered in Ramat Gan, Israel, with additional operational offices in Antwerp (Belgium), New York (USA), and Mumbai (India). The platform serves professional diamond traders and jewelry retailers, providing a searchable live database of more than one million polished diamonds from global diamond centers, a proprietary transaction clearing function (Guaranteed Diamond Transactions, or GDT) that guarantees availability, authentication, consolidated international shipping, and secured payment, and the IDEX Diamond Index, which has been published continuously since 2004 and is updated hourly as an industry-standard pricing benchmark derived from $5+ billion in inventory.

The product surface extends beyond the core marketplace into data and distribution: IDEX Onsite offers embedded diamond search and APIs (natural and lab-grown diamonds, refreshed every two hours) that allow customers to integrate IDEX inventory into their own websites, while Real Time Prices, the weekly Price Report, and IDEX Research provide market intelligence reaching a readership of 65,000. Supporting products include iOS and Android mobile apps, BoxxStars (sealed certified natural melee diamonds), and Buy Now Pay Later and Asset Based Financing services for accredited members. The IDEX Online News platform functions as a content and research vertical that reinforces the company's position as an industry information source.

The business model combines a three-tier subscription (IDEX Basic free, IDEX Premium at $720/year, IDEX Pro at $1,080/year), GDT transaction fees, add-on API / Onsite fees, and financing spreads. With 7,000+ professional traders regularly using the platform and more than 75% of the supply chain inventory featured, IDEX operates as a horizontal two-sided marketplace whose monetization is split across subscriptions, transactions, data access, and trade finance, anchored by a multi-decade proprietary pricing dataset.

Broad incumbents

• Blue Nile (Signet Jewelers): Blue Nile, now owned by Signet Jewelers, is one of the largest online diamond and fine jewelry retailers globally. While primarily a consumer-facing B2C platform, its scale and online diamond configuration capabilities make it an adjacent comparable for IDEX's B2B marketplace model and benchmark for digital diamond retail infrastructure.
• Rosy Blue: Rosy Blue is one of the world's largest diamond manufacturers and wholesalers with operations spanning the entire supply chain from rough sourcing to polished distribution. As a broad incumbent in B2B polished diamond supply, it represents the type of large-scale traditional seller whose inventory feeds into platforms like IDEX.
• Stuller: Stuller is a large U.S.-based B2B manufacturer and wholesale distributor of jewelry, findings, and loose diamonds serving independent jewelers. As a broad incumbent in the jewelry supply ecosystem with diamond sourcing capabilities, it overlaps with IDEX in serving professional jewelry buyers seeking polished diamonds at wholesale, though via inventory ownership rather than an exchange model.

Direct peers

• RapNet / Rapaport: RapNet is the longest-established online B2B polished diamond trading platform operated by Rapaport, providing inventory listings, pricing benchmarks (RapNet Price List), and trade services. It is IDEX's most direct competitor for the same professional trader and jewelry retailer base across major diamond centers, with overlapping value propositions in search, pricing, and transaction facilitation.
• GemFind: GemFind operates a diamond and jewelry search platform with affiliate feeds and feeds/inventory integration for retail jewelers, similar to IDEX Onsite. It competes for the same white-label/embedded diamond search use case, providing retailers with diamond listings, supplier attribution, and API-based inventory integration.

Regional players

• Leibish & Co. Leibish & Co. is a specialist retailer and trader of fancy color diamonds (yellow, pink, blue) with online direct channels and a strong presence in the colored diamond niche. While operating more as a specialty retailer than a B2B exchange, it is comparable to IDEX as an online diamond marketplace and benefits from the same industry price-transparency trends that IDEX pioneered.

Emerging players

• Sarine Technologies: Sarine Technologies provides advanced diamond manufacturing, grading, and scanning technologies, including AI-based planning and evaluation. While its core focus is upstream diamond processing rather than trading, Sarine's data and grading services increasingly feed into B2B marketplaces, positioning it as a complementary (and potentially competing) infrastructure provider in the digital diamond value chain.
• Polygon (Tracr): Polygon, formerly Tracr, is the blockchain-based diamond traceability platform launched by De Beers and now an independent industry consortium. It overlaps with IDEX at the inventory-data infrastructure layer, providing provenance and grading data feeds that compete with IDEX Onsite's API distribution and could threaten IDEX's positioning as the primary data backbone for diamond trade.
