Everyone loves receiving mail the old fashion way. There’s a certain romance to getting a physical letter or a postcard. And jewelry is always romantic. So it was obvious to London-based designer Nutre Arayavanish to put the two together as Postable Jewelry. Her hard postcards with pop out pieces can be constructed into creative rings or necklaces. While these jewels aren’t exactly 14 karat, they’re the perfect answer to “sorry, I was traveling and missed your birthday/anniversary/wedding.”
