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 critter-rific necklace from Able Made, which donates part of its proceeds to charity. Want to offer something that’s truly one of a kind? Detroit’s Rebel Nell employs disadvantaged women to make pretty baubles from fallen graffiti.
