Avon necklace large links silver tone 18 inch chain

This is an Avon necklace. It is silver tone with large oval links connected with double chains made up of smaller links. The large links are about 7/8" long and 5/8" wide. The necklace has an overall length of 16 to 18 inches depending on where you place the securing hook. This is in very good condition and cleaned up with silver polish so I think it has a silverplate coating.
