Orion's Belt, scaled for a second piercing. The Orion Flatback Stud lines up three round-cut CZ, prong-set edge to edge along a bar of solid 14k gold — 4mm long, 2mm wide. From across the room it's one flash of light; up close it's a row of three, which is the whole point.
The post sits at the center of the bar, so you choose the angle — horizontal, vertical, or tilted to follow the line of your ear — and at 4mm it fits the spots a round stud crowds: a high lobe, a helix, the gap between two hoops. Small enough to disappear into a stack, sharp enough to hold its own alone.
Finished with a comfortable threaded flatback — the flat post goes in from the back, the top screws on, and it sits smooth against the ear for all-day (and sleep-in) wear. Solid 14k gold, cubic zirconia, sold as a single. Line them up.
