Our "Ideation" earrings measure 1.3/4" by 2.0". Each circular piece has three hand-carved lines and it dangles from an angular earwire that is soldered shut. Materials: 14k gold-fill (14k gold over brass core/no nickel) or sterling silver (.925) with oxidized sterling silver. All materials are hypoallergenic. We hand carve and oxidize the lines on these earrings. The oxidation is protected within the carved lines and therefore better preserved over time. These earrings were designed for 's first capsule collection in Asbury Park and are handmade in our Upstate New York production studio.
