Vintage Pendant - Pearl? Shell? - Repair Needed To Bail

Vintage Pendant - Pearl? Shell? - Repair Needed To Bail Measures about 1.75". Bail is made from wire and is broken and will need a repair or twisting onto a chain. Some marks. Not sure of material. Not sure if some staining or just the natural gradiant of whatever material it is. Possible some tarnish to the wire (not sure if it is tarnish or not). Preowned vintage, sold as shown - I am unsure of material type(s) because of this. Pictures show different angles for you to review - while I attempt to note any defects, some tarnish/signs of wear may be visible that are not otherwise stated. If you have any questions please feel free to drop me a message.
