Jewelry set with rough-cut stones is still flooding store shelves, but while most unpolished styles skew a bit bohemian, Oak has come up with a sleek (surprisingly affordable) take on the trend.This geode bangle pairs a modern marbled acrylic cuff with a chunky slice of agate. While the stone has that plucked-from-nature look, the silver plating around the edges means it won't snag your winter sweaters.

Black bangle with stone and crystal inset, $32 at Oak or online.
