What’s happening this weekend at the Nevada County Fairgrounds? It’s the Earth’s Treasures Gem and Mineral Show! Held in Main Street Building on Saturday and Sunday (October 10 and 11) from 10 am to 5 pm, there is a huge selection of vendors. Stop 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, 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. Presented by the Nevada County Gem and Mineral Society, more information can be found here.
