Body jewelry featuring a specific alloy of gold and copper, often with a touch of silver, colored pink or reddish-gold and designed for navel piercing adornment is widely available. This type of ornamentation presents a distinct aesthetic. For example, a curved barbell made from the aforementioned metal alloy is commonly used.
The appeal of this jewelry stems from its warm hue and perceived association with luxury and sophistication. Historically, pink-toned gold has enjoyed periods of popularity in various forms of jewelry, offering a departure from traditional yellow gold. Its use in navel rings provides an alternative to surgical steel or other metals commonly used in body modification, catering to individual preferences in style and material sensitivities.
