The NJ Mineral, Fossil, Gem & Jewelry Show returns to the New Jersey Convention & Exposition Center (NJCEC), at 97 Sunfield Avenue, Edison, NJ 08837. Although it is often associated with the wider Plymouth-area event calendar, the show itself is held in Edison, Middlesex County. It is organised by InterGem, Inc. and uses more than 150,000 square feet of exhibition space, with around 300 vendor booths.

The autumn edition is scheduled for 30 September to 4 October 2026. The information available for the May edition lists opening hours of Wednesday to Friday, 12 noon to 8pm; Saturday, 10am to 7pm; and Sunday, 10am to 6pm. It is sensible to check the organiser’s current details before travelling, particularly for the autumn dates and ticket arrangements. Reviews mention admission prices of around £16, with one review referring to a £15 three-day re-entry pass; these figures may not be the current prices and are shown here only as a guide.
There is plenty to browse beyond finished jewellery. Stalls typically offer diamonds, beads, pearls, opals, precious and semi-precious gemstones, engagement rings, settings, watches, chains, findings and jewellery supplies. Visitors can also find custom jewellery, vintage and estate pieces, home décor, gifts, hair accessories, and cleaning or repair services. The show’s more unusual features include a 38-foot T-Rex skeleton, a minerals room lit with ultraviolet light, and children’s activities such as fossil digs. Reviews describe it as a family-friendly event, especially for children interested in fossils and geodes. At the same time, some recent comments say the show feels smaller and more expensive than it did before the pandemic, while others still appreciate the range of materials and sellers. Mentioned exhibitors include The Gneiss Guy, Nativa / oh my Druzy, and High Quality Fossils by Mark.
The NJCEC is close to I-95, I-287, the Garden State Parkway and US Routes 1, 9 and 35, making it practical by car. It is roughly 15 minutes south of Newark Liberty Airport and about 40 minutes south of Midtown Manhattan, depending on traffic. For questions, InterGem lists (301) 294-1640 and www.intergem.com.
