Make spirits bright this holiday with gifts of jewelry that pander the planet as much as their recipients. Add some polish to a loved one’s attire with a pair of hand-hewn cuff links made from recycled brass. Or double your impact with a repurposed bracelet from The Giving Keys, which donates part of its proceeds to help homeless and low-income individuals find and retain jobs. Want to offer something that’s truly one of a kind? Rebel Nell employs disadvantaged women from Detroit to make pretty baubles from fallen graffiti.
