This is a wonderful old Victorian Love Knot pin from the late 1800s. Two pieces of twisted rope are entwined to form the design. My jeweler has confirmed that the pin is gold filled. There is an old c clasp and tube hinge. It appears the pin stem was replaced many years ago. Measurements are 1 7/8 inches by a little less than 5/8 inch at the widest part. It is in good condition and is highly wearable.
