San Francisco–based jewelry line Iacua is giving the green-minded locals something natural to wear on their sleeves. Founder Ruby Iacuaniello recently launched her spring collection of nature-inspired pieces molded from found objects—twigs she came across at her parents’ house, succulents from her own garden, and even picked blackberries. Each piece is made by hand and customizable. She makes them in all kinds of metal: a variety of golds (in both 14k and 18k) and oxidized and non-oxidized silvers. The silver-and-black-diamond Coral Medallion she wears around her neck is both girly and bold. It’s currently one of a kind, but don’t worry, she’ll make you one, too. etsy.com/shop/iacua
