Exposed brick walls and 120-year-old pressed-tin ceilings at downtown Moscow's Gem State Crystals house unique jewelry, fossils, rocks and artifacts representing more than a billion years of geology and life in Idaho and the world.

A step through the street-side showcase leads to the sounds of on-site jewelers hammering metal, the sights of Earth's dazzling crystals and even the feel of fossilized dinosaur dung.

For 35 years the family-owned business has provided rock hounding tips, customized jewelry and repair and stonecutting – with a specialization in star garnets.
