INSTASALE: Measuring 7.5 in this bracelet features a Black Onyx Inlay sterling cross and a small miraculous medal. All beads and components are sterling silver. The beads in this one are one of my favorite stones. You are seeing Black Tourmaline beads, semi precious labradorite with black tourmaline inclusions. You have to see the stone in person it has this beautiful blue flash I could not get in a video.
