GEMFINITY
GEMFINITY is a B2B valuation and trading platform for diamonds and colored stones, designed for the gemstone industry. It provides dealers, manufacturers, and traders with accurate, market-anchored valuations using its proprietary MGL Valuer engine. This engine goes beyond traditional Rapaport list pricing by incorporating a six-layer pipeline: Rapaport baseline, quality adjustments, manufacturer premiums, market discounts, negotiation behavior, and export margins, resulting in dual ex-works and platform prices. The platform supports major gemological laboratory certificates (GIA, IGI, GCAL, AGL, GRS, Gübelin, SSEF) with certificate OCR for seamless input. Real-time market intelligence is a core feature, aggregating live pricing data from global bourses, RapNet, VDB, and verified manufacturer feeds, refreshed every three minutes. Users can access historical price trends back to 2020 and built-in RAPI index tracking. The platform also provides inventory management and trade tools, including bulk import from RapNet/VDB, anonymous partner matching for negotiation, and integrated escrow and compliance services. Every stone listed is tied to a live valuation and a certificate of provenance, ensuring transparency. GEMFINITY is built for the way the trade actually works, claiming 98.2% valuation accuracy versus realized trade prices and an average valuation time of 42 seconds. Trusted by over 3,200 verified dealers across 42 countries and having valued $284 million in trade volume year-to-date, it offers a free tier with three valuations and then moves to a paid model. The platform aims to replace spreadsheet-based pricing and phone call negotiations with a centralized, data-driven trade desk.

Problem solved
Gemstone dealers and traders traditionally rely on Rapaport list prices, which are theoretical and do not reflect actual transaction prices, leading to lengthy negotiations, lack of confidence in valuations, and inefficient trade settlement. Gemstone market data is fragmented and opaque, making it difficult to assess fair market value in real time. GEMFINITY solves this by anchoring valuations to verified market ex-works data, providing live, aggregated pricing intelligence, and integrating trading tools. This allows users to obtain defensible, accurate valuations in seconds, compare multiple price layers, and conduct trades with verified counterparties directly on the platform, reducing time, cost, and uncertainty.
