Sy Kessler Sales

What Sy Kessler Sales does

Sy Kessler Sales, Inc. is a privately held Dallas, Texas–based B2B distributor and manufacturer of professional jewelry and precious-metals equipment, organized under the GEMORO brand and a set of sub-brands (Kessler Lab Grown Diamonds, Kessler Batteries/Kessler Settings). The company sells diamond and moissanite testers, gold and platinum testers, XRF gold and precious-metal analyzers (Made in USA), ultrasonic and steam cleaners, precision scales (carat and gram) including METTLER TOLEDO jewelry balances, microscopes and loupes, ring sizers, gemstone gauges, permanent jewelry welders, and a full line of cleaning solutions and accessories. It also holds the U.S. 'Official Importer and Distributor' relationship for Murata Batteries (formerly Sony watch batteries) and distributes YEHUDA AI-powered lab-grown diamond detectors (Watson AI, Sherlock AI, Big Sherlock).

The product portfolio is built on a set of proprietary patented technologies, including the UV-F1 Moissanite Identification system (capable of detecting super-low conductive Forever One moissanite), ColorLast permanent-color technology for CZ master diamond-color grading sets, the AuRACLE line of patented gold and platinum testers, and the KESSLER SETTINGS click-lock stone-holder patents covering square/princess hidden and round micro-half-bezel holders. The KESSLER SETTINGS technology enables gemstone setting in roughly 10 seconds per stone without traditional prongs, in materials ranging from precious metals to titanium, ceramic, and carbon fiber.

The firm operates primarily through direct B2B e-commerce (sykessler.com), a MAP-enforced authorized reseller network requiring resale permits, event-driven field sales at JCK Las Vegas (2026 Essentials & Tech Booth #52091) and NPA Pawn Expo (2026), and equipment financing through Sunbelt Lessors for higher-ticket items. Customers are segmented across jewelers and jewelry retailers (primary), pawn shops (primary), watch repair professionals (secondary), and luxury-product manufacturers (secondary) via the KESSLER SETTINGS line. Pricing is per-unit hardware sale with one-time/perpetual licenses, MAP enforcement for GemOro-branded products, and accessory/consumable-driven recurring revenue (replacement probes, calibration discs, cleaning solutions). Brand marketing is anchored by NASCAR O'Reilly Auto Parts Series car sponsorships (#39 RSS Racing/Ryan Sieg, #99 Viking Motorsports/Parker Retzlaff), multiple branded Instagram/Facebook properties, and dedicated YouTube training content, with export distribution governed by U.S. sanctions compliance (excluding Belarus, Cuba, Iran, North Korea, Russia, Syria, Sudan, and specific Ukraine regions).
