Cornicello

A cornicello is a twisted horn-shaped charm often made of gold, silver, plastic, bone, terracotta, or red coral.

[1] Cornicelli are thought to be modeled after an eland horn, to represent fertility, virility, and strength.

[3] The evil eye is believed to harm nursing mothers and their babies, bearing fruit trees, milking animals, and the sperm of men - the forces of generation.

In addition to being worn as jewelry, cornicelli are sometimes hung from the rearview mirrors of cars (based on the older custom of using them to protect draft horses), and in houses.

"[1] This gesture is performed with the hand levelled or pointing down, or at least slightly downward, usually with a swivelling or oscillating motion.
