Chinese Carved Stone Pendant Stone Crystal Multi-Colored Pearl Bead Necklace

Chinese Carved Stone Pendant Stone Crystal Multi-Colored Pearl Bead Necklace. Pre-owned, this necklace is in excellent almost vintage condition. The pendant has one slight chip in the stone as seen in the next to last photo and a small chip in one of the stones as seen in the last photo. This has a patent pending ball through donut clasp. Measures 18" long. I am not sure what the stone is but it registers in the jadeite range on my gem tester. Not a lightweight. N758
