International Gem & Jewelry Show, Inc.®

What International Gem & Jewelry Show, Inc.® does

International Gem & Jewelry Show, Inc.® (InterGem®) is a privately held, family-owned operator of a traveling direct-to-consumer jewelry show circuit in the United States. Founded in 1966/1967 by Herbert A. Duke, Sr. and Bettye Duke and currently run by their children Arnold, Danny, and Roxane Duke, the company produces 60+ shows annually across 35+ major U.S. cities, reaching an estimated 200,000+ attendees per year. Its core product is a physical marketplace event in which jewelry wholesalers, manufacturers, and designers sell directly to consumers at prices typically reserved for the trade, supplemented by free jewelry cleaning and specialty exhibits such as celebrity estate jewelry.

The underlying technology stack supporting this event-led business is modest and conventional: iOS and Android mobile applications for show notifications and schedules, an online ticketing storefront, the Ungerboeck exhibitor management system, and the Gems & Jewelry Magazine as the official on-site publication. Adjacent modules include a wholesale-buyer registration system with credential verification, a free school/teacher admission program, and InterGem Premier Auctions, an online auction offering operated via a partnership with LiveAuctioneers. No proprietary AI, data platform, or significant software IP is disclosed.

The revenue model rests on three streams: (1) consumer ticket sales at $6 online / $8 at the door (cash only), with free admission for active/veteran military, licensed wholesale buyers, and qualifying schools; (2) exhibitor booth rentals paid by wholesalers, manufacturers, and designers (pricing not disclosed); and (3) magazine and on-site advertising sold to exhibitors via the Gems & Jewelry Magazine. The company is headquartered in Rockville, Maryland, operates with approximately 23 employees, and has no disclosed external investors, parent company, or M&A activity.

Direct peers

• Beadfest: Touring bead, gem and jewelry show circuit serving hobbyists and jewelry-makers across multiple US cities. Closely comparable travel-show business model, audience overlap in the beading and jewelry-making segment.
• AGTA GemFair Tucson: American Gem Trade Association's annual Tucson show focused on colored gemstones and jewelry. Direct competitor for exhibitor and wholesale buyer attention within the gem/jewelry show category.
• Atlanta Jewelry Show: Long-running US jewelry trade show serving retail jewelers with wholesale buyers. Comparable B2B exhibition model in the jewelry trade fair category with similar mid-tier retail/wholesale positioning.
• Select Jewelry Shows: Independent regional jewelry exhibition circuit in the US Southwest with vendor booth rentals and wholesale buyer focus. Comparable to InterGem's regional traveling jewelry show model.
• Couture (Couture Trade Show): Invitation-only US luxury jewelry trade show held in Las Vegas. Comparable high-end jewelry exhibition model targeting both wholesale buyers and curated designer-vendor attendance.
• Tucson Gem, Mineral & Fossil Showcase: Multi-venue gem and mineral show circuit held annually in Tucson, AZ (45+ shows). Closely comparable traveling-event show model targeting gem/jewelry buyers, wholesale and retail, with overlapping vendor base.

Broad incumbents

• JCK (Reed Exhibitions): Largest US B2B jewelry trade event (JCK Las Vegas) plus JA New York, organized by Reed Exhibitions/RX. Operates a far larger scale and international buyer base, but focuses on B2B trade rather than InterGem's direct-to-consumer model.
• Hong Kong Jewellery & Gem World (JGW): Premier international B2B jewelry trade show organized by Informa Markets. Geographically distant but directly comparable as a multi-vendor jewelry exhibition serving both wholesale buyers and manufacturers.
• Vicenzaoro (Italian Exhibition Group): Major European jewelry trade fair held in Vicenza, Italy, twice yearly. Comparable as a large-scale international jewelry exhibition serving wholesale and retail buyers with a strong manufacturer/exhibitor base.

Others

• Premiere Show (Premiere Merchandise Mart): Multi-city trade event operator in jewelry and accessories with traveling showroom format. Indirectly comparable as a trade-show operator in adjacent consumer categories like apparel/accessories.
