Worthy

Worthy is an online consumer-to-business (C2B) auction marketplace for pre-owned luxury goods, including diamonds, diamond jewelry, loose stones, and branded watches. Sellers ship their items to Worthy headquarters in New York, where pieces undergo professional grading and appraisal — GIA or IGI for diamonds, CentralWatch authentication for watches — before being listed in timed online auctions open exclusively to a network of professional buyers. Worthy handles the full logistics pipeline: insured shipping, grading, auction management, and payment disbursement. The platform was founded by investment banker Ben De-Kalo in 2014 after a personal experience highlighted the lack of fair resale options for high-value jewelry. Approximately 85% of auctions close successfully above the seller's agreed reserve price.
