Welcome to the Roseville Rock Rollers Gem and Mineral Society's annual Gem, Jewelry, Fossil & Mineral Show! This highly anticipated event, held every year, is a celebration of the fascinating world of gems, minerals, fossils, and lapidary arts.

Silent Auction

Explore Bargin Treasures and Uncover Remarkable Finds

The Silent Auction is a highlight of our Annual Gem and Mineral Show, offering attendees the opportunity to bid on and win a variety of unique and valuable items. As many previous attendees can attest, the Silent Auction is the cheapest field trip you will ever make. With a chance to acquire rare and beautiful items at unbeatable prices, you don't want to miss out. And remember, if you walk out of the show with a straight back unbowed by the load you are carrying, you’ve missed the auction area and need to return to complete your successful field trip.
