What G. N. Diamond, L.l.co. does

GN Diamond is a B2B wholesale supplier of natural and lab-created diamonds and finished diamond jewelry, headquartered in Philadelphia, Pennsylvania with a cutting and polishing facility inside the Tel Aviv Diamond Exchange (Bursa) in Ramat Gan, Israel. The firm is family-owned and has operated continuously for over 30 years (with corporate materials citing 40+ years of category experience), serving more than 4,500 independent retail jewelers across the United States, Canada, and the Caribbean under a strict policy of refusing consumer-direct or online-portal sales. Its catalog spans approximately 9,000+ certified natural loose diamonds (GIA / EGL USA) and 8,000+ certified lab-grown loose diamonds (GIA / IGI), in eight shapes, alongside finished jewelry programs covering diamond studs, tennis bracelets, solitaire pendants, huggies, and 5-stone/fancy wedding bands.

The technology stack is anchored by four proprietary components: the patented GemPrint optical fingerprinting system for positive diamond identification (in use by the FBI and Canadian Government since 1976); Light Performance analysis using a multi-angle red laser to grade light return on a Fair–Excellent scale, delivered free on every natural diamond; a 360-degree diamond imaging pipeline for online presentation; and the Diamond Hunt virtual-inventory platform that lets retailers surface GN's entire in-stock catalog on their own websites under their own markup logic. The GN Diamond App complements Diamond Hunt as an in-store mobile sales tool, while the GN Exchange Program lets jewelers monetize any over-the-counter natural diamond transaction by routing the stone back to GN for distribution and re-cutting.

The business model is wholesale take-rate pricing on loose stones (with diamonds priced up to 55% off Rap, including Light Performance and insurance-discount registration at no charge) plus trade-in-guaranteed finished-jewelry programs at fixed unit prices (e.g., 1.00 ctw B-quality studs at $1,915; 5.00 ctw B-quality 7" bracelets at $5,280). Go-to-market is direct B2B field sales supported by trade-show presence at JCK Las Vegas, IJO Louisville, and RJO Lexington; account self-registration via gndiamond.com; a recurring webinar series co-produced with Shane Decker's Ex-sell-ence Academy and Instore Magazine; and a free marketing-asset library distributed to retailer partners. All pricing is final and non-negotiable per company policy.
