EAR HALOS are fitted, small, 14k yellow solid gold hoop earrings aka "Ear Huggies". You can leave these in indefinitely and they won't tarnish or become irritating. Added benefits of gold include; it is naturally antimicrobial, energizes the solar plexus, supports circulation, is the metal of royalty.
These are classic, understated, minimalist earrings; everyday piercing jewelry you can sleep-in. The 10mm diameter Halo is an "endless hoop" style (no backs, fully closed) suitable for almost any piercing. I have them in my first and third ear piercings. This size hugs the ear and leaves a tiny bit of wiggle room space depending on the thickness of your skin. They fit perfectly in the ear lobe, conch, tragus, helix, cartilage and also nose rings and septum rings.
