Leather has been everywhere these past couple of seasons, and thanks to By Boe's newest collection, we can now rock it on our fingers as well. The Stapla line (out this fall) features leather and 14-karat gold filled stackable rings either knotted or not. They're available in a variety of colors from forest green to plum, and even includes a spring-y mint green one. Starting at 15 dollars a pop, who can resist collecting (and stacking) them all?
