The Zoe Halo Sterling Silver Threaders are stunning, made with White Zircon. Zircons are a natural stone, with a high brilliance, diamond-like lustre and beautiful shine. They are minimal yet they make a statement. The length is adjustable so can be worn day to night. You can team these with our Zoe Halo Studs for that double sparkle, or just mix and match for an edgier look..
