Marenakos Rock Center in Preston is holding a stone auction and art sale, Saturday, Dec. 17, with proceeds going to charity.

Staff noticed long lines in front of a local food bank, and were moved to help others. They chose three causes to benefit, Seattle Children’s Hospital, Leukemia and Lymphoma Society, and Northwest Harvest.

Art, sculptures, paintings, drawings, jewelry and other items will be sold, as will be various sorts of stones.

“There will be something for everybody,” said Scott, one of the owners. “Whether you are a contractor or a homeowner or just a rock enthusiast, you get to nameyour price and, best of all, you are contributing to a good cause.”

The auction is 10 a.m. to 3 p.m. at the center, 30250 S.E. Highpoint Way, Preston.
