To celebrate Earth Month, we enlisted a handful of green-loving designers to earmark an item exclusively for InStyle, and pledge to donate a portion of this month’s sales to charities that improve the environment. For today’s post, we’re highlighting Jennifer Fisher.

Jennifer Fisher has the golden touch. The New York-based jeweler, who’s created chic custom pieces for Rihanna and Miley Cyrus, is taking a cue from her sustainable designer counterparts and greening up her precious metals. How? By donating a portion of the proceeds from her 18-carat gold feather charm (above, left) to Waves for Water, a nonprofit that provides clean H₂O to communities around the globe.

Fisher’s delicate dangler is a fitting piece for the eco-charity. “I imagined the feather on the necklace floating on water when I designed it,” she says. Wear the chain on its own as a single-statement piece or layer it over others for a super-gilded effect. “We need to do whatever we can to save the planet,” says Fisher. So why not start with shopping? Snag Jennifer Fisher’s charm for $1,200 at jenniferfisherjewelry.com—remember, it’s for a good cause!
