This is a decorative Ankh

The Ankh is an ancient Egyptian hieroglyphic symbol that represents "life". It is one of the most recognizable symbols of ancient Egypt and is often depicted in art and inscriptions. The Ankh was associated with the afterlife and was often carried by gods and pharaohs.
The loop of the Ankh may symbolize the eternal soul, while the cross represents the physical world.
Together, they represent the union of heaven and earth, and the promise of eternal life.
Ankhs were often made of various materials, including wood, stone, and metal. They were worn as amulets, carried in processions, and placed in tombs to ensure the deceased's safe passage to the afterlife. Modern interpretations of the Ankh are popular as jewelry and decorative items, often incorporating various designs and materials.
