The Marysville Rock &Gem Club will bring some hot gem information to this cool time of year during its 36th annual “Rocktoberfest” Gem and Mineral Show.
The free show is set for 10 a.m. to 5 p.m. Saturday and Sunday in the Totem Middle School cafeteria at Seventh Street and State Avenue in Marysville.
Among the club’s usual display cases of rare stones, gems, knives and jewelry this year will be a case devoted to obsidian stones, which are created by molten lava flows, according to press materials. Another case will feature spheres, or rocks that formed into ball-like shapes.
Lava flow products will have an additional role in the show. Club members say all school-age children in attendance will receive a sample of petrified wood, the state’s official gem. Much of the state’s petrified wood grew next to ash-spewing volcanoes between 5 million and 12 million years ago.
In addition to all the sparkling rock sights, eventgoers may watch gem shaping, grinding, polishing and wire-wrapping demonstrations on both days.
