Those fascinated by geologic history, collectors of fossils or crystals, makers of jewelry, and lovers of all things sparkly will congregate this weekend at The Rochester Lapidary Society's 41st Annual Rochester Gem, Mineral, Jewelry, & Fossil Show and Sale, to be held at the Main Street Armory (900 E. Main St.).

The show will feature vendors, activities for kids, demonstrations, raffle prizes, beads, crystals, fossils, minerals, jewelry, carvings, spheres, a straw draw, hourly door prizes and more. This year's show theme is "Thinking Outside the Jewelry Box," which challenged entrants to create and submit non-jewelry pieces which incorporate gems, fossils, beads, minerals, and rocks in works of fiber, glass, or wood.

The show hours are Saturday, October 26, 10 a.m.-6 p.m., and Sunday, October 27, 10 a.m.-5 p.m. Admission is $6 (children under age 12 accompanied by an adult get in free), or $9 for a two-day pass. Students receive half price admission with valid school issued ID. For more information, visit rochesterlapidary.org or facebook.com/ROCGemShow.
