Ear adornments featuring a planar reverse side, often constructed from a precious yellow metal, represent a specific design choice in jewelry. This configuration, particularly when rendered in gold, offers an alternative to traditional post and butterfly closures. An example would be a small, solid gold stud with a completely flat disc resting against the earlobe, secured by a threaded post and screw-on backing.
The significance of this design lies in its enhanced comfort and security. The flat backing distributes pressure more evenly across the ear, reducing irritation, especially during sleep. Furthermore, the screw-on closure minimizes the risk of loss compared to friction-based backings. Historically, gold has been favored for its hypoallergenic properties and enduring aesthetic appeal, making it a desirable material for jewelry intended for prolonged wear.
