You can paw through sparkly stuff galore this weekend at the Cuyahoga County Fairgrounds, as nearly two dozen local artists and international dealers set up shop for the annual GemStreet USA show. Based in Lakewood, GemStreet USA brings together all sorts of minerally magic: Among the wares, you’ll find tabletop specimens of fossils, crystals, and geodes, DYI-ready beads, supplies, and faceted gemstones, and completed pieces of artisanal jewelry in an assortment of precious metals. (Custom work is also an option.) Show hours are 10 a.m. to 6 p.m. today and Saturday; on Sunday, hours are 11 a.m. to 5 p.m. General admission is $7 for adults, $5 for students and seniors, and free for kids under 12. Hang on to your ticket, because it’s good for all three days. More good news: parking is free. Find details at www.gemstreetusa.com.
