Brass
Brass body jewelry has a golden yellow color.
Brass body jewelry should only be worn in completely healed piercings. Wearing brass jewelry through eyelets is a great alternative to wearing it directly in your piercings.
Brass is an alloy of copper and zinc. Alloys are mixtures of various elements and help change the color, melting temperature and strength of the elements. The yellower the brass, the less copper and more zinc.
