Vintage Art Deco carved rock crystal bead necklace, hand knotted, with Chinese character carvings, 112 grams

Fantastic carved rock crystal bead necklace. I believe it is rock crystal rather than glass due to its provenance and what I have been told about the piece. Each large, clear bead is carved Chinese characters.

The necklace is hand-knotted on thread and fastens with a silver tone spring ring clasp. The necklace has a length of about 18 inches and is in very good vintage condition.
