The NY / NJ Mineral, Fossil, Gem and Jewelry Show is organized and run by Eons Expos, and nearly fills the 150,000 sq. foot NJ Convention & Expo Center in Edison, NJ. The show features always-changing special exhibits to keep folks coming back every year for the 3-day annual event. Eons Expos is comprised of a team of three Jersey siblings and their family friend. The team also organizes similar shows in the Denver Coliseum, which is the largest gem show in the USA with 3 miles of tables, and in Tucson, which is the most-attended gem show in the USA with 50,0000 visitors.
