Nevada County Gem & Mineral Society

Main Street Center at the Nevada County Fairgrounds

Come by to see the fantastic displays of gem and mineral collections, visit the booths of the numerous vendors, bid on minerals and rocks at our silent auction, listen to see if your number is called for the twice-hourly raffle, watch local artisans at work, and see the demonstrations. The Earth’s Treasures is a great place to meet other enthusiasts, buy supplies to feed your passion, and experience everything the rock and mineral hobby has to offer.
