Stone: Kyanite Metal: Recycled Copper Sometimes you're mid-epiphany, scribbling notes for your next massive project or venture, and your hair gets all up in your face. We know the struggle. That's why we have these gorgeous gem-tipped hair pins to keep your glorious locks in place while you're getting down to business. Please allow for slight variation in stone size, shape and color as each stone is unique. Our hair pins are made out of copper, and as a natural metal, the color can patina. We embrace this beautiful process, but a simple polish with a jewelry cloth will bring your hair pin back to its full shine.
