Registration Is Open for the HardRock Summit
AGTA GemFair and the Denver Gem & Mineral Show also will have a presence on the show floor.

The third annual event will be held at the Colorado Convention Center from Sept. 15-18. About 250 gem, jewelry, and mineral companies are expected to exhibit.
Co-founders Christoph Keilmann and Wolter Mehring said they decided to return to the state’s capital after receiving positive feedback from exhibitors.
“With its European flair, HardRock Summit is exactly what the American market needs: a well-organized, upmarket, and sophisticated arena for the mineral and the gem world communities," said Ian Bruce of Crystal Classics.
The September timing also proved to be a success, organizers said, ideal for buying, sourcing, and trading.
The four-day show draws jewelry designers, manufacturers, bench jewelers, silversmiths, and mineral collectors.
The American Gem Trade Association’s GemFair and the Denver Gem & Mineral Show also will have spaces on the show floor.
“AGTA is thrilled to be participating for our third year with the HardRock Summit,” said AGTA CEO John Ford. “Denver provides an exciting venue for our exhibitors and buyers to network before the holiday selling season.”
Admission is free for qualified jewelry professionals and buyers who wish to attend.
The public is also welcome and will have access to the entire show floor, except the AGTA GemFair section.
“With an unparalleled array of offerings from raw and cut gemstones to entry-level and high-end minerals, HardRock Summit will once again be the must-attend event for the mineral and jewelry industries in the fall season,” organizers said.
