Hexagon Eco-resin Posts These handmade Hexagon Eco-Resin post earrings are made from eco resin, jeweler's brass, and sterling silver posts. A signature mix of colored eco-resin and silver sparkles is hand-poured into each piece, creating a simple yet sophisticated look in the earrings. The posts are made in sterling silver. Every piece is handmade by me in my studio in North Carolina. Please note, as these earrings are handmade, slight variations may occur, making each pair truly unique.
