Vintage Bond Boyd Sterling 21" 2mm Rope Chain with Onyx & Green Stone Pendant VG

This 50s chain with pendant is used but in very good condition. There is very light scuffing on the silver of the pendant from use. The chain measures approximately 21" end to end. The pendant measures approximately 1.5" x 1". The flower petals are looped silver wire. There is a tiny green stone. I am an unsure what it is exactly. It comes with a gift bag.
