You wouldn’t call yourself a superhero. But damn if you don’t feel like one sometimes. At such moments, you may want to slip on a SuperKarin ring. Inspired by science fiction, mechanical toys, comic books, and Japanime, the collection of rings is categorized by themes such as “flower,” “matrix,” “cocktail,” and “rocket.” Each design balances chunky metal with clean lines in shapes that are bold and fantastical but also totally wearable. And because they’re made with sterling silver and lab-grown or less expensive gems, they’re pretty affordable. Which should leave you feeling even more super. If such a thing is possible. Available at All About Jane, 2839 Clarendon Blvd., Arlington (703-243-4424). To see styles, go to superkarin.com.
