Up for sale is this Fine Old Antique Chinese Carved Hallowed Bovine Bone Flat Bead Necklace. It came from a local estate sale. I'm not an expert on these necklaces. This listing is based on the research I've done. In great condition for its age. The clasp is in excellent condition and holds tight. Measures 16 inches long. Not cleaned or polished -- left in its natural vintage state (which serious collectors prefer). You're gonna love it! Peace.
