The Plumb Club

What The Plumb Club does

The Plumb Club is a private, membership-based trade association founded in 1983 and headquartered in Englewood, New Jersey, that operates as a coalition of jewelry, diamond, and watch industry suppliers. The organization represents well over 100 jewelry, watch and service brand members, connecting supply-side companies with jewelry retailers through educational resources, networking, and industry events. Its core offerings include a monthly podcast series, annual market and consumer research, webinars on topics such as diamond traceability and commodity pricing, a trends content hub, reference documents and charts, and an annual Symposium held in New York City in partnership with JCK and Jewelers Mutual.

The Plumb Club's underlying platform is a reengineered website (launched March 2026) that serves as a daily starting point for retailers, featuring an AI-powered search experience, live gold/silver/platinum metal pricing, a Jewelers Resource Hub, enriched member profile pages, and visual product search across the member network. The organization requires all members to maintain Responsible Jewellery Council (RJC) certification, a standard adopted in September 2019 that distinguishes The Plumb Club from competing trade bodies and supports responsible sourcing across the supply chain. Marketing and distribution are primarily digital (website, podcast, weekly newsletter, social), with event-driven engagement anchored by the annual Symposium.

Revenue is generated through membership dues paid by jewelry suppliers, manufacturers, diamond traders, and service providers, supplemented by event sponsorships. Operating geographies are concentrated in North America (United States), although membership now includes international suppliers such as Kama Jewelry (described as a top Asian manufacturer) and Shivani Gems. Staff size is small (1-10 employees), and the organization is governed by a Board of Directors and currently led by President Roger Forman, with Michael Lerche serving as Pavilion Chairman following a transition from the presidency.

Scale indicators3 records

Recent moves6 records

Expansion highlights6 records

Emerging players

• Jewelers Mutual Group: Insurance and risk services company that co-sponsors the Plumb Club Symposium and recently became a Plumb Club member. Comparable as a B2B service provider to jewelry retailers, increasingly overlapping with Plumb Club's education and member-services remit.

Direct peers

• Jewelers of America: National US trade association for retail jewelers offering education, benchmarking, and advocacy. Comparable in mission and member-services model to Plumb Club, but serves the retailer side rather than the supplier side of the supply chain.
• American Gem Society (AGS): US jewelry trade association focused on ethical business practices, gemological standards, and retailer certification. Comparable peer providing membership services, certification, and industry education in the same jewelry ecosystem.
• Responsible Jewellery Council (RJC): Global standards-setting organization for the jewelry and watch industry with 2,000+ member companies. Plumb Club requires its members to be RJC certified, making RJC both a deep partner and a comparable membership/standards body operating in the same industry.
• Manufacturing Jewelers & Suppliers of America (MJSA): Long-standing US jewelry trade association serving manufacturers and suppliers with education, events, and advocacy. The most direct functional peer to The Plumb Club — both organize suppliers, run conferences, and offer industry resources, though MJSA is more manufacturing-technical while Plumb Club leans marketing/retailer enablement.

Broad incumbents

• CIBJO (World Jewellery Confederation): International federation of national jewelry trade organizations covering gemological, ethical, and trade standards globally. A broader, more policy-focused incumbent in the same association space — referenced in Plumb Club's own industry news coverage.
• GIA (Gemological Institute of America): Leading gemological research, education, and grading organization offering membership, courses, and certification. A broader incumbent in jewelry industry standards and education that overlaps with Plumb Club's educational content offering.
• JCK (Jewelers Circular Keystone): Major jewelry industry media and events business that co-hosts the Plumb Club Symposium. Functions as both a partner and an overlapping industry resource platform with news, events, and B2B content serving similar audiences.

Regional players

• World Federation of Diamond Bourses (WFDB): International federation of diamond exchanges. Comparable trade-association model serving diamond industry participants, but globally federated rather than US-supplier-focused like Plumb Club.
• International Colored Gemstone Association (ICA): Global trade body for the colored gemstone industry. Comparable as an industry association connecting suppliers with the broader market, but with a colored-gemstone specialization that complements rather than competes with Plumb Club's broader jewelry focus.
