Dealers

Space is allocated from a waiting list

The show fills every year. Returning dealers are contacted directly each spring, and remaining space is offered from the waiting list — so we do not publish booth sizes or rates, and we cannot hold a space against a payment.

To be considered, tell us what you sell. Contracts are handled by John Corbett and Lindsay Schneider, who will be in touch when space comes up.

Join the dealer waiting list

We need to know what you sell before anything else — the show is balanced across minerals, fossils, jewelry, beads and lapidary supplies, so the mix matters as much as the space.

Please do not send payment with an enquiry. Space is confirmed by contract only, and a check does not reserve a booth.

Work in progress

The online enquiry form isn't wired up yet.

Email John Corbett directly at corbett67@comcast.net and tell him what you sell — he handles the waiting list with Lindsay Schneider.

The show runs on volunteers

Set-up Thursday, Kid's Area shifts Friday through Sunday, tear-down Sunday afternoon. Shifts are a few hours. Bring gloves and sturdy shoes for set-up and tear-down; everything else is provided.
