800 Silver Rolo Choker Necklace

This necklace does not test as sterling silver, but less pure so I am calling it 800 silver.  Southwestern style rolo necklace features 7.5mm polished oval links and 6.5mm twisted oval links, and the links are not soldered.  The necklace measures 17 inches in length and it weighs 35.7 grams.  It is in great vintage condition.
