Vintage / Antique Multistrand Choker Necklace

Vintage / Antique Multistrand Choker Necklace I am not even sure where to start describing this necklace. This is truly a piece of history--and art. Although this necklace is not perfect it is still absolutely stunning. The center pendant is a cluster of clear rhinestones--set in what I believe may be sterling (not tested...nor marked). The pendant is suspended by three strands of cream / opaque beads--I suspect the beads are either moonstone or recycled glass. Hook/loop closure. Approximately 12" with extension Flaws (all pictured) : 1. there is one stone missing from the pendant. 2. One bead is cracked 3. There is slight bending on pendant edge 4. Significant tarnish/corrosion around the hook area and ends of the pendant 5. The thread appears to be original and is fragile Note: Most of my jewelry is pre-loved. I only wipe down jewelry. I do not deep clean any jewelry before shipping. I am not a professional and do not want to risk damaging any vintage item. There may be a small amount of verdigris. I will note any flaws/defects. Lighting might affect the colors in the photos. I will try to describe as accurately as possible. Please see all photos and do not hesitate to ask questions.
