For all the double piercing lovers, this new stud (sold as a single) has two cubic zirconia stones (2.5mm and 5mm) linked with a 4mm long box chain.  It's meant to be worn in two separate piercings and is crafted in 18K gold vermeil heavily plated over solid 925 sterling silver.  It's also nickel-free making it perfect for those with metal sensitivities.
