Altair packs a constellation into 3mm: three round CZs, each in its own polished bezel, clustered into one bright little triangle of solid 14k gold.
The bezels do the quiet work — every stone sits flush in a smooth rim of gold, so nothing catches on hair or sweaters and the cluster reads as one solid piece of light. Named for the third star of the Summer Triangle: the sky's brightest trio, now at earlobe scale.
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. Three's not a crowd.
