Jewelry featuring a smooth, planar rear surface crafted from a precious yellow metal allows for comfortable and secure placement. This design, often found in post-style body adornments, minimizes irritation by sitting flush against the skin. A typical example is a stud designed for earlobe or cartilage piercings, constructed entirely of 14k or 18k gold, where the posterior portion is uniformly level.
The appeal of this design lies in its enhanced comfort and reduced likelihood of catching on clothing or hair. This is especially significant for individuals with sensitive skin or those who wear earrings continuously. Historically, gold has been prized for its hypoallergenic properties and enduring value, making it a desirable material for body modification that has been considered and has withstood the test of time.
