What UNI Diamonds does

UNI Diamonds is a B2B digital marketplace and data platform for the global diamond trade, connecting jewelry retailers, wholesalers, and diamond manufacturers to a network of 450+ suppliers listing over 2 million diamonds with a combined inventory value of approximately $3.5 billion. Founded in 2018 and headquartered in Hong Kong, the company operates as the commercial arm of an Israeli technology developer (U.N.I Technologies Ltd), with related entities handling distribution in Hong Kong (UNI Luxury Group Limited) and the United States (UNI Luxury USA INC), plus active sales presence in India, Belgium, Italy, and the UK.

The platform combines a free-to-browse marketplace with a paid AI-powered analytics subscription (Smart+/UNI Data) that delivers real-time price-per-carat analysis, supply/demand trends, and the industry-first GIA Price Check tool, which links GIA diamond certificates to actual market transaction prices for benchmarking. Technical differentiators include API integration enabling enterprise customers to connect directly to UNI's inventory programmatically, an Augmented Reality try-on feature, a White Label Customer App for retailer-branded in-store browsing, and a Pair Diamonds matching service. Logistics are handled through a core partnership with Malca-Amit, providing access to 200 vault locations globally, insurance, secure delivery, and up to $100,000 in diamond-collateralized inventory financing. The company is a member of the Responsible Jewellery Council and operates under De Beers' Best Practice Principles, and holds a Category A Dealer in Precious Metals and Stones registration in Hong Kong.

Revenue is generated through three streams: (1) transaction fees (U.N.I Fee) on diamond sales completed through the marketplace, (2) subscription revenue from the Smart+ and UNI Data analytics platforms sold via a sales-led enterprise motion, and (3) financing services tied to Malca-Amit vault collateral. The go-to-market is sales-led with direct enterprise outreach, complemented by a freemium marketplace funnel, industry event presence, and digital marketing.

Others

• Leibish & Co. Leibish is an online diamond and fancy color diamond retailer. While predominantly B2C rather than B2B, Leibish represents an adjacent diamond commerce model using technology-driven sourcing and could overlap with UNI on the supply side as a sophisticated buyer/seller.
• Malca-Amit: Malca-Amit is UNI's core logistics and vaulting partner and a leading global secure logistics provider for precious goods. As a critical ecosystem enabler rather than competitor, Malca-Amit's services underpin UNI's integrated fulfillment, insurance, and financing offerings.
• GIA (Gemological Institute of America): GIA is the dominant diamond grading and certification authority and UNI's strategic data partner for the GIA Price Check product. While not a direct competitor, GIA's data assets and industry relationships are foundational to UNI's value proposition and could become competitive if monetized more directly.

Emerging players

• Ritani: Ritani is an online diamond and engagement ring retailer with a B2B platform connecting jewelers to a curated diamond inventory. It competes with UNI for retail jeweller mindshare and offers marketplace functionality combined with virtual try-on technology.
• Tracr (De Beers Group): Tracr is a blockchain-based diamond traceability platform from De Beers covering provenance and supply chain integrity. While more provenance-focused than UNI's trading focus, Tracr competes in the broader digitization of diamond commerce and shares UNI's enterprise B2B buyer audience.
• Sarine Technologies: Sarine provides diamond manufacturing and grading technologies including AI-based diamond analysis and traceability. It overlaps with UNI's analytics and grading-adjacent capabilities and represents a technology-led peer expanding into the same diamond data intelligence space.

Broad incumbents

• Stuller: Stuller is a large US-based jewelry manufacturer and wholesaler offering finished jewelry, findings, and loose diamonds to retail jewelers. While broader in scope than UNI, Stuller competes for the same retail jewelry procurement wallet and offers in-house B2B sourcing tools.

Direct peers

• IDEX Online: IDEX is an online B2B diamond and jewelry trading marketplace with price indexing and trading tools. It competes directly with UNI for diamond trading volume and offers comparable listing, search, and pricing transparency services.
• Polygon (Polygon.net / Diamex): Polygon is a long-established B2B online diamond trading platform competing for the same wholesale buyer and supplier base as UNI. Both platforms provide real-time inventory search, pricing data, and trading tools to jewelry professionals globally.
• Rapaport (RapNet): Rapaport operates RapNet, the largest global B2B diamond trading network and the dominant incumbent in the same product category UNI targets. Both platforms serve diamond wholesalers, retailers, and manufacturers with marketplace, pricing, and analytics tools, making RapNet UNI's most direct competitor.
