The Spike Tennis Necklace was born from the dream of Zanni one day having her own tennis bracelet, but she never quite connected with the options out there. True to the ZANNI ethos, Zanni started by flipping the diamonds upside down, exposing the pointed culet instead of the brilliant face.Satin-finished sterling silver and intentionally imperfect black antiquing, buffed away in areas to reveal an almost brushed aluminum finish, the result feels worn in and industrial. Just the right amount of punk.
