Vintage Baguette Knot Gold Tone Herringbone Chain Necklace 16"

This vintage gold tone necklace features a stunning knot pendant with baguette-shaped rhinestones. The herringbone chain measures 16 inches in length and has a snap closure. The necklace is not signed and has a yellow gold plated metal. Looks like a diamond necklace. Estate item and have no other info about it or age. I get stuff from demolition homes where the people leave their belongings. My brother has a demolition company where I go pick.
